Input Fuse and Reverse Polarity Protection A metal oxide varistor (voltage dependent resistor VDR) together with the input filter form an effective protection against high input voltage transients, which typically occur in most installations An incorporated fuse protects the converter against further damage in the case of a failure Note: The fuse is not customer-accessible Table : Fuse specification Model Fuse rating Reference CDP/5 5 V, 5 A T Schurter SPT 5x, 55 CPA/5 5 V, 5 A T Schurter SPT 5x, 5 CPD5 8 V, 5 A F Littlefuse FKS, 66755 CPA5/55 5 V, A T Schurter MXT5, 4695 To avoid unwanted power losses, the CPD/5 models are not protected against reverse polarity at the input by a serial diode, but only with an antiparallel diode In the case of reversed input voltage, the input fuse will blow; however no further damage will occur The CPD5 models are protected against reverse polarity by a special ry, which generates no losses The converter will simply not start-up, but no damage will occur The CPA Series converters are designed for AC input and have a rectifier bridge on the input Input Current Limitation All converters incorporate an active inrush current limiter in the input ry, which reduces the peak inrush current value by a factor of 5 to protect connectors and switching devices from damage Note: The inrush current limitation is achieved using electronic ry For effective limitation the converter should not be switched on and off more frequently than every 8 seconds Input Undervoltage Shutdown CPD/5 models start at approx V i = V, when the input voltage is applied; at decreasing V i, they switch off at approx V Note: The input current I i may exceed I i max, if V i V i min CPD5 models start at V i = 5 V and switch off at V i = V CPA models exhibit an undervoltage trigger ling start-up and shutdown The threshold is between 8 and 9 VAC See also Power Fail Signal Note: CPA/5 with version V6 should not be operated at V i V i min, as these models have no undervoltage shutdown and will therefore operate with a high input current at full load Efficiency The efficiency is specified in table Its dependence upon the input voltage V i is shown in fig a (CPA models) and fig b (CPD5 models) The efficiency of CPD/5 models depends only marginally upon V i η [%] 9 86 8 78 CPA5/55 CPA/5 5 5 5 VAC Fig a CPA Series: Efficiency versus input voltage JM8a η [%] 86 85 84 8 CPD5 5 6 7 V Fig b CPD5 Series: Efficiency versus input voltage JM4 Page 6 of

Hold-up Time of CPD Models For extended hold-up time of CPD models, use external output capacitors or decoupling diodes and input capacitors of adequate size Formula for additional external input capacitor: P o (t h total t h ) C i ext = η (V ti V i min ) whereas: C i ext = external input capacitance [mf] P o = output power [W] η = efficiency [%] t h total = total hold-up time [ms] t h = hold-up time [ms] V i min = minimum input voltage [V] = threshold level [V] V ti Note: After V i was removed, the outputs maintain their voltage for the time t h Even if V i comes back during t h, but after t h, the output voltage might be affected Redundant Operation and Hot Swap Due to the integrated FETs/diodes, the converters are designed to be operated in redundant systems Hot swap is also possible, but the output voltages of each bus may deviate dynamically by 5% during the plug-in / plug-out operation Note: We recommend connecting some capacitors parallel to the bus to limit voltage deviations during hot swapping and during switch-on / switch-off of the input voltage of one of the parallel-connected converters Output Characteristic and Protection All outputs are fully protected against continuous open- (no load) and continuous short- conditions All outputs of CPx/5 models have a constant current limitation with a rectangular characteristic; see figure In addition, the total power from outputs Vo, Vo, and Vo is limited to P o max, resulting in a free choice of load distribution between these outputs Output Vo4 is disabled in the case of overtemperature generated by overcurrent In CPA5/55 and CPD5 models, the total power of all four outputs is limited to P o max In all models, all outputs are monitored for an overvoltage condition If an overvoltage of % is detected, the converter is permanently disabled To reset, the input voltage must be removed for seconds Note: The models CPA5/55 with version number before V need approx 6 s to recover V o /V o nom 95 I o max I o L 586b 5 I o Fig Typical output characteristic V o versus I o Page 9 of

Thermal Considerations and Protection If a converter is mounted in the upright position with airflow as specified in the general conditions of the tables 4 and 5, allowing unrestricted forced-air cooling, and is operated at its nominal input voltage and power at maximum ambient temperature T A max (see Temperatures), the temperature at the measurement point of the case temperature T C (see Mechanical Data) will approach after an initial warm-up phase the indicated maximum value of T C max (5 C) However, the relationship between T A and T C depends heavily on the operating conditions and the system integration The thermal conditions are significantly influenced by the input voltage, the output current, the airflow, and the temperature of the adjacent elements and surfaces T A max is therefore, contrary to T C max, an indicative value only Caution: The installer must ensure that under all operating conditions T C remains within the limits shown in the diagrams fig 4 P o /P o nom P o /P o nom JMa 59c LFM = m/s 6 Convection cooling in upright position 5 LFM = 5 m/s Convection cooling in upright position LFM = m/s 5 5 T A min 5 6 7 8 9 C T A min 5 6 7 8 9 C Fig 4a Output power versus temperature T A at V i nom (CPD/CPA) Fig 4b Output power versus temperature T A at V i nom (CPD/CPA5) P o /P o nom JMb LFM = 5 m/s (CPA/CPD5) LFM = m/s (CPA55) Convection cooling in upright position 6 5 CPA/CPD5 CPA55 T A min 5 6 7 8 9 C Fig 4c Output power versus T A at V i nom (CPA5/55, CPD5 Note: Forced-air cooling (or an additional heat sink on customer -specific models) can improve the reliability or allow for higher T A, as shown in the diagrams fig 4, but T C max shall never be exceeded A temperature sensor fitted on the main PCB provides approx C below T C max a warning signal (DEG#), at which the logic begins to reduce the output power The output power returns to the normal value, when the temperature drops back below this limit; see Temperature Warning and Shutdown Page of

Output Filter The output ripple voltage can be reduced by an external filter to less then 5 mv pp Recommended values: C, C: Low ESR capacitor, eg, OS-CON 47 µf L, L: Choke 47 µh with appropriate rated current, eg, Coiltronics HCLP µh / A or µh /4 A 46 JMb 4 VoSENSE Vo Ω L 5 V Input 8 VoSENSE Vo Ω L V C C 47 5 RTN Gnd Fig 5 Output filter reducing the output ripple of Vo and Vo An alternative solution is shown in green Auxiliary Functions Inhibit and Enable The inhibit input INH# enables (logic high) or disables (logic low, pull down) all outputs, when a logic signal (TTL, CMOS) is applied In systems consisting of several converters this feature may be used to the activation sequence of the converters or to enable the source to start-up, before full load is applied When INH# is low, the converter cannot be activated by the EN# pin Note: If this function is not used, the inhibit pin 9 can be left open- (not connected) If pin 9 is connected to a return pin (eg pin ), the internal logic will disable all outputs The inhibit input is protected by a decoupling diode EN# (pin 7) is CMOS-compatible However, we recommend to connect it directly with a return pin (eg pin ) to enable the converter Pin 7 is shorter than the others, ensuring start-up only, after all other pins were connected to the system This provides true hot-swap capability Note: When a CPA or CPD5 converter is disabled by INH# and/or EN#, the PFC booster remains active, keeping the boost capacitor C b (fig ) charged As a result, there is no inrush current at restart Note: When a CPD 5/55 converter is disabled, on outputs and 4 may appear a little voltage under no-load condition This can be avoided by a small preload Table 6: Inhibit characteristics Characteristics Conditions min typ max Unit V inh Inhibit voltage V o = on - 8 V i min V o = off 4 5 t r Rise time t d Delay time depending on I o V ms 46 65d INH# 9 V o /V o nom 655a EN# 7 t V INH# t r t f 47 RTN () Inhibit t Fig 6 Inhibit and enable inputs Fig 7 Typical output response as function of inhibit voltage Page of

Temperature Warning and Shutdown A temperature warning ry monitors the case temperature T C Its output signal V DEG# changes from high to low impedance, when the T C exceeds the upper threshold level, and changes back to high impedance, when T C falls below the lower threshold level, which is 85 C ± 5 C Pin 8 (degrade signal DEG#) is internally connected via the collector-emitter path of an NPN transistor to the signal return pin The current I DEG# through pin 8 should not exceed ma, and V DEG# should not exceed V If T C exceeds 5 C, the converter will be disabled It resumes operation automatically, once T C falls below 5 C 46 56a Vo V DEG# [V] 589c P o /P o max R p 8 thermal shutdown 8 Input 8 DEG# I DEG# 6 4 signal DEG# 6 4 47 V DEG# RTN 6 7 8 9 C Fig 8 Degrade signal: NPN output V DEG# V, I DEG# ma Fig 9 Degrade signal V DEG# versus case temperature T C Power Fail Signal The power fail ry monitors the input voltage V i and all output voltages The signal V FAL# changes from high to low impedance (<5 V), when one of the monitored voltages falls below the threshold V FAL# changes back to high impedance, when all monitored voltages exceed their threshold level The threshold level for V o corresponds to approx 9% of V o nom The threshold levels for V i correspond to approx 4 V for CPD models and 8 9 VAC for CPA models Note: CPD/5 (and CPA/5 up to version V6) provide only the signal FAL#, but the converter is not inhibited Note: V i min of CPA models is considered as insufficient, when V i remains for typ ms below V i min Connector pin 4 (signal V FAL# ) is internally connected via the drain-source path of a JFET (self-conducting type) to the signal return pin The current I FAL# should not exceed ma V FAL# should not exceed V, as the JFET is not protected against overvoltage JM 46 Vo R p Input 4 FAL# I FAL# V FAL# 47 RTN Fig Power Fail: JFET output, I FAL# ma Page of

Sense Lines This feature is available only for the outputs Vo, Vo, Vo, and allows the compensation of voltage drops across the connector contacts and if necessary, across the load lines To ensure correct operation, all sense lines S (VoSENSE, VoSENSE, and VoSENSE) should be connected to the respective power outputs The common sense return S (SRTN) should be connected to RTN (pin 5 ) Note: Open sense lines are admissible, but the output voltage regulation will be poor The voltage difference between any sense line at its respective power output pin (as measured on the connector) should not exceed the following values Note: If the sense lines S and S compensate for a considerable voltage drop, the output loads shall be reduced in order to respect the maximum output power Table 7: Sense line data Output [V] Total voltage difference between sense lines and their respective outputs 8 V 5 V V Active Current Sharing for Vo, Vo, Vo The current share facility, consisting of a single-wire link, should be used, where several converters are operated in parallel connection, for example, high reliability n redundant systems or systems providing higher output power Note: Maximum six converters can be connected in parallel Using this feature reduces the stress of the individual converters and improves the reliablity of the system Interconnection of the current sharing terminals causes the converters to share the output current evenly In n redundant systems a failure of a single converter will not lead to a system failure, since the outputs are already decoupled by FETs and diodes internally Passive Current Sharing for Vo4 The output voltage changes slightly with the output current (droop characteristic) ensuring automatic current sharing without further precautions when several converters are connected in parallel An increase in output current decreases the output voltage according to fig V o 4% % CPx/5 588c V o4 set % 4% CPx5/55 5 I o / Fig Output voltage V o4 versus output current I o4 Page of

Safety and Installation Instructions Connector Pin Allocation The connector pin allocation table defines the electrical potentials and the physical pin positions on the Positronic connector Pin no 45 (protective earth) is a leading pin, ensuring that it makes contact with the female connector first Installation Instructions These converters are components, intended exclusively for installation within other equipment by an industrial assembly process or by a professionally, competent person Installation must strictly follow the national safety regulations in respect of the enclosure, mounting, creepage distances, clearance, casualty markings, and segregation requirements of the end-use application Connection to the system shall be made via the mating female connector (see fig 6) Other installation methods may not meet the safety requirements Check for hazardous voltage, before altering any connections Connector: Positronic PCIH47MA or similar Mating female connector: Positronic PCIH47FA or similar 5 7 9 5 7 9 4 6 8 4 6 8 Fig 9 Pinout of the front connector 4 7 6 9 4 5 8 4 7 4 6 9 5 8 4 44 Table : Pin allocation of the front connector 46 87a 45 47 Pin Length Signal name Description - 4 B Vo Output 5 - B RTN Return (Vo and Vo) - 8 B Vo Output 9 B RTN Return (Vo) B Vo Output C Vo4 Output 4 C RTN Return C Reserved Reserved 4 C RTN Return (Vo4) 5 C nc Do not connect 6 C Reserved Reserved 7 D EN# Enable 8 C nc Do not connect 9 C nc Do not connect C VoSENSE Vo remote sense C nc Do not connect Pin Length Signal name Description C nc Do not connect C VoSENSE Vo remote sense 4 C SRTN Sense return 5 C VoSHARE Vo current share 6 C VoSENSE Vo remote sense 7 C nc Do not connect 8 C DEG# Degrade signal 9 C INH# Inhibit C nc Do not connect 4 C VoSHARE Vo current share 4 C FAL# Fail signal 4 C nc Do not connect 44 C VoSHARE Vo current share 45 A CGDN Chassis ground 46 A DCIN 4 ACN 5 Pos DC input 4 Neutral line 5 47 A -DCIN 4 ACL 5 Neg DC input 4 Line input (phase) 5 Pin numbers shown are for the female backplane connector A = very long pins, B = long pins, C = short pins, D = very short pins Pin 45 of the female connector is leading, ensuring that chassis ground makes contact first 4 CPD models (DC input) 5 CPA models (AC input) The converters are provided with a leading pin no 45, which is reliably connected to the case For safety reasons it is essential to connect this pin to the protective earth of the supply system The input DCIN or ACL (pin no 47) is internally fused; see Input Fuse and Protection This fuse is de signed to break an overcurrent in case of a malfunction of the converter and is not customer-accessible Page 9 of

External fuses in the wiring to one or both input lines (pin 47 and/or pin 46) may be necessary to ensure compliance with local requirements A built-in second fuse in the neutral line (pin 47) is available as option F for CPA5 models A second fuse in the wiring to the neutral line or option F may be needed if: Local requirements demand an individual fuse in each source line Neutral and earth impedance is high or undefined Phase and neutral of the mains are not defined or cannot be assigned to the corresponding terminals Caution: Installation must strictly follow the national safety regulations Models with option F: Caution! Double-pole/neutral fusing Do not open the converters, or the warranty will be invalidated! Important: If the inhibit function is not used, pin 9 (i) should be left open- to enable the outputs Enable Pin 7 (EN#) should be connected to pin (RTN) to enable the outputs Make sure that there is sufficient airflow available for convection cooling This should be verified by measuring the case temperature, when the converter is installed and operated in the end-use application The maximum specified case temperature T C max should not be exceeded Make sure that a converter failure (eg by an internal short-) does not result in a hazardous condition Standards and Approvals The converters are safety-approved to the latetest edition of UL/CSA 695- and IEC/EN 695- The converters correspond to Class I equipment The following considerations have been made during design concerning safety: Build-in component Functional insulation between output(s) and case Use in a pollution degree environment A suitable fire enclosure shall be provided at end use CPD-models: Basic insulation between input and case/output, based upon 75 VDC The input is identified as TNV- CPA-models: Basic insulation between input and case, and double or reinforced insulation between input and output, based upon 5 VAC CPA-models up to 6 Hz The converters are subject to manufacturing surveillance in accordance with the above mentioned standards Isolation The electric strength test is performed in the factory as routine test in accordance with EN 554 and IEC/EN 695; see table Only the test between input and [caseoutputs], marked with footnotes and, may be repeated by the customer Notes: The DC test voltage shall be slowly increased (within several seconds) and maintained for max seconds Trigger level 5 µa The factory is executing these tests with a rea sonable margin, to guarantee its repetition Test with AC is not possible due to the incorporated Y caps However, the standards allow testing with a corresponding DC voltage The Company will not honor warranty claims resulting from incorrectly executed electric strength tests Table 4: Isolation Characteristics CPD models CPA models Unit Input to (Case Output) Output to Case Input to (Case Output) Output to Case Electric strength test Factory test s 5 7 7 VDC AC test voltage equivalent to factory test 5 5 5 VAC Insulation resistance at 5 VDC > > > > MΩ According to IEC/EN 695, subassemblies connecting input to output are pre-tested with kvdc According to IEC/EN 695, subassemblies connecting input to output are pre-tested with 4 kvdc or kvac Page of

Operation at >6 Hz and Leakage Currents Operation up to 4 Hz is possible, but the X and Y caps are not safety-approved to this frequency The efficiency decreases by approx %, and the leakage currents are proportional higher Protection Degree and Cleaning Liquids The converters correspond to protection degree IP, provided that the female connector is fitted The power supplies are not hermetically sealed In order to avoid possible damage, any penetration of cleaning and other fluids shall be avoided Safety of Operator-Accessible Output Circuits If the output of a converter is operator- accessible, it shall be an SELV according to the IEC/EN 695 related safety standards However, it is the sole responsibility of the installer to ensure the compliance with the relevant and applicable local safety regulations Options L: Output Current Latch All CPA/CPD models exhibit a latching shutdown, which is activated if only one output voltage is too high; see Output Characteristic and Protection If option L is fitted, this latch is as well activated, if the current limit of one output is exceeded for approx 5 s A: Face Plate without Logo No logo is not printed to the front plate F: Built-in Second Fuse Available for CPA5 models only A nd fuse in the neutral input line provides safe phase to phase connection at low mains voltages (eg, USA /8 V /6 Hz systems) The built-in second fuse enables safe connection to the mains, where phase and neutral line are not defined, as eg, in the case of plug and socket connection to the mains via German Schuko-plugs; see also Safety and Installation Instructions C: Protective Lacquer All boards are covered by a protective lacquer G: RoHS RoHS-compliant for all six substances This feature is standard NUCLEAR AND MEDICAL APPLICATIONS - These products are not designed or intended for use as critical components in life support systems, equipment used in hazardous environments, or nuclear systems TECHNICAL REVISIONS - The appearance of products, including safety agency certifications pictured on labels, may change depending on the date manufactured Specifications are subject to change without notice Page of
