Safety according to IEC/EN , UL/CSA , IEC/EN 5078, IEC 600-, UL ".9" Description The Convert Select front end series represents a family of DIN-rail mountable DC-DC and AC-DC converters with power factor correction. The converters have been designed according to the latest industry requirements and standards. The converters are ideal for use in outdoor and other demanding applications to power building control systems, factory automation, industrial controls, instrumentation, electromagnetic drives, fans, and other DC loads. Different models are available with a single output or two independently regulated, electrically isolated outputs with,, 6, or 8 V. Special models for battery charging are available. The EW models are particularly suitable for 0 V railway applications; they have been designed in accordance with the railway standards EN 5055 and EN 50. Key features of the Convert Select line include power factor correction with low harmonic distortion, negligibly low inrush current, high immunity to transients and surges, and low electromagnetic emissions. Internal protection circuits such as input over- and undervoltage lockout, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system. The outputs deliver an electrically-isolated Safety Extra Low Voltage, SELV, (except models LWR/LWN70) and low output noise. They are no-load, overload, and short-circuit proof. The electronically controlled short-term peak power capability of up to 50% of the rated output power enables the front end converters to deliver additional power to start-up motors or to safely operate subsequent circuit breakers. Built-in large sized output capacitors absorb possible reverse energy, which may be caused by quick deceleration of electromagnetic drives connected directly to the output. A green LED at the front cover displays the status of the output(s). The Convert Select Series was designed according to all relevant international safety standards. The converters are approved by TÜV and UL, and are UL 508 listed. Adequate Table of Contents Page Page Description... Model Selection... Functional Description...

2 5, 50 Watt AC-DC and DC-DC DIN-Rail Converters clearances and creepage distances allow operation in pollution degree environment (with AC input). All board assemblies are coated with a protective lacquer. The thermal concept allows operation at full load up to an ambient temperature of 60 C (LW models) or 70 C (EW models) in free air without forced cooling. A rugged DIN snapfit device allows easy and reliable fixing onto the various 5 mm DIN rail models. The converters are fitted with cage clamp terminals easily accessible from the front. System connectors with screw terminals for use with pre-assembled harnesses, external adjustment of the output voltage as well as various auxiliary functions are available as options. The letter E stands for improved EMC performance of LW models. Model Selection Table : Standard models Output Output Output Power Operating Input Type Effic.

Specific type designation, input voltage range, nominal output voltages and currents, degree of protection, batch no., serial no., and data code including production site, version, and date of production. Functional Description The W Series converters are primary controlled AC-DC or DC- DC flyback converters with a constant switching frequency of 0 khz. The power-factor-corrected single-step conversion of the input voltage to a low output voltage results in extremely high efficiency. Depending upon the output power, the converters are fitted with one (5 W) or two (50 W) powertrains. Models with two powertrains have one or two outputs. Double-output models exhibit indiviually regulated powertrains. The input voltage is fed via fuse, filter, and rectifier to the main transformer, designed in planar technique. The input filter with very small input capacitance generates virtually no inrush current. An input transient suppressor protects the converter against high voltage peaks and surges. Input over- and undervoltage lockout as well as input current limitation protect the converter from operation outside of its specification. The input voltage waveform is sensed by the primary control logic to allow active power factor correction, forcing the input current to follow the input voltage waveform. The secondary side of the main transformer supplies via the rectifier diode a large electrolytic output storage capacitor providing for the hold-up time. Double-output models exhibit an individual control logic each. The output voltage and the output current are measured and fed back to the primary control logic via an optocoupler. A second control loop monitors the output voltage. It disables the output in the case of a failure in the control logic and limits the output voltage. Built-in temperature sensors monitor the internal temperature of each powertrain. If the temperature exceeds the limit, the converter reduces the output power continuously to keep the temperature below its limit. A green LED on the front cover confirms the presence of the output voltage(s). The R input (option R, M, or M) allows for external adjustment of the output voltage by means of a resistor or an external voltage source. An external sensor can be connected to the R input and allows for temperature-controlled battery charging (see Accessories). 00a L Vo+ N Vo Fuse nd fuse (option F) Input filter Rectifier C y C y Input filter Shunt C y Shunt + Output filter C Y Vo+ Vo 9 Control circuit including PFC and input OVP/UVP V o /I o control nd control loop (SELV) C Y 0 AUX Fig. LWR 5 W and LWN 50 W single-output converters.

7 5, 50 Watt AC-DC and DC-DC DIN-Rail Converters Output Power Derating The output power of LW models must be decreased at low input voltage and/or powertrain temperature above 5 C. The powertrain temperature depends on the output power, the input voltage, and the cooling method. At low input voltage the losses increase. At the maximum specified environment temperature T A free air convection cooling might be insufficient approaching maximum ambient conditions. As a result, the output power has to be reduced according to the tables below. Note: The measurements have been made by the approval boards with free air convection cooling according to UL specified ambient temperature T A and with the converter built in a cardboard box according to UL 508 and a specified temperature outside the box T out. The tables give a correlation between T A or T out and the case temperature T C (measuring point T C see Mechanical Data). For models not specified, please contact Power-One. EW models have no derating.

EW models have a smaller fuse (50 V, 9 mm, SOC NT 6.A V009, ULrecognized E-965). For DC input voltages above 50 V observe the Installation Instructions. Converters with option F have small fuses, one in each input line. Converters with option E and F have large fuses (T6.A, 5 0 mm). The DC input voltage for all converters with option F is limited to 50 V. A VDR and a symmetrical input filter form an effective protection against input transients. An under- and overvoltage lockout protects the converter, which is disabled below V i min and above V i max by an internally generated inhibit signal. The built-in bridge rectifier provides reverse polarity protection at the input if operated from DC. EW models are protected by the (blowing) input fuse in connection with the body diode of the main transistor. Option Q offers a serial diode, but this affects efficiency by approx. %.

11 5, 50 Watt AC-DC and DC-DC DIN-Rail Converters Parallel Operation Double-output models exhibit an independant control logic each. Both outputs can be connected in parallel, provided that the options S (included in M) and R are not used, since they influence only the nd output. The two power trains share the current due to their output voltage droop characteristic. Up to converters with the same output voltage may be operated in parallel. It is possible to parallel W Series with X Series converters. Reasonable current sharing is achieved by the droop characteristic. Correct mode of operation is highly dependent upon the wiring of the converters and the impedance of these wires. Use wires with equal length and equal cross sections of min..5 mm. The best results for parallel operation can be achieved with the wiring shown in fig. 6. Parallel operation of single-output models using option R (output voltage adjust) is possible, but not recommended. Refer to fig. 6; the connections between the pins 8 and 9 (both Vo ) should be as short as possible. Note: Parallel operation is not possible, if the temperature sensor is connected, as the sensor eliminates the output voltage droop. Series Connection Series connection of several outputs up to 50 V is possible. Exceeding an output voltage of 60 V, the output is not SELV. Output Characteristic and Protection The output characteristic, individual for each powertrain, is rectangular with a droop to ease parallel operation; see fig. 7. However, a 50% higher output current is possible for a short time, such allowing startup of loads or charging of capacitors; see fig. 8. Each output is independently protected against internal overvoltage by means of a second control loop. When the output voltage exceeds V o L, the respective output is disabled. Overtemperature Protection A built-in temperature sensor protects each powertrain is independently protected against overtemperature. When a certain temperature is reached, the concerned powertrain reduces its output power continuously.

Thermal Considerations The thermal conditions are influenced by input voltage, output current, airflow, and temperature of surrounding components. 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 stated in the table Temperature specifications. Note: Sufficient forced cooling allows T A to be higher than T A max provided that T C max is not exceeded. It is recommended that continuous operation under worst case conditions of the following parameters be avoided: Minimum input voltage, maximum output power, and maximum temperature. which provides temperature controlled adjust of the trickle charge voltage. This optimizes charging as well as battery life time. Depending upon the cell voltage and the temperature coefficient of the battery, different sensor types are available; see Accessories. Note: Parallel operation is not possible, if the temperature sensor is connected to the paralleled outputs Vo+, as the sensor eliminates the output voltage droop. However, it is possible to insert bleeding resistors in the Vo+ output lines of each converter in order to create a droop of approx. 0.6 I o nom for V outputs (. I o nom for 8V outputs), but this creates considerable power losses.

Pin designation Electrical determination Protective earth PE N Input neutral, DC negative L Input phase, DC positive Installation Instructions The converters of the W Series are components, intended exclusively for inclusion within other equipment by professional installers. Installation must strictly follow the national safety regulations in compliance with the enclosure, mounting, creepage, clearance, casualty, markings and segregation requirements of the end-use application. DIN-rail mounting is possible with the built-in snap-fit device on a DIN-rail. This fulfills the mechanical transport requirements as per ETSI , class (vertical). To fulfill the requirements of IEC 7--, class. (vertical), additional fixing brackets DMB-EWG [formerly HZZ006] (see Accessories) must be fitted on the bottom side of the DIN-rail. For heavy duty railway applications, we recommend installing all fixing brackets DMB-EWG. Wall mounting is possible with the wall-mounting brackets UMB-W [HZZ0068] (see Accessories). This complies with IEC 7--, class. (vertical and horizontal). Caution: Install the converters vertically, and make sure that there is sufficient airflow available for convection cooling. The minimum space to the next device should be: top/bottom: 0 mm, left/right: 0 mm.

This fuse is designed to break an overcurrent in case of a malfunction of the converter and is not customer-accessible. External fuses in the wiring to one or both input lines (L and/ or N ) may be necessary to ensure compliance with local requirements. A built-in second fuse in the neutral path is available as option F. A second fuse in the wiring to the neutral terminal N or option F is 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 (L to phase and N to neutral). Models with Option F: Caution! Double-pole/neutral fusing. If the converters operate at source voltages above 50 VDC, an external fuse or a circuit breaker at system level should be installed. Caution: Installation must strictly follow the national safety regulations. Do not open this apparatus! Standards and Approvals The converters of the LW Series with feature E were approved by TÜV according to IEC/EN :00 (IEC/EN for models without E), IEC 600-:C:00 (models without E: IEC 600-), and EN 5078:997 (with and without E). The converters were further approved by UL according to UL (models without E: UL950), CAN/CSA C. No as UL508-listed components. Safety approvals for EW models are in process. The converters have been designed in accordance with said standards for: Class I equipment Power-supply for building-in, vertical mounting on 5 mm DIN-rail or on a wall Overvoltage category II (III for 0 VAC supply) Basic insulation between input and case, based on 50 VAC Double or reinforced insulation between input and output, based on 50 VAC and 50 VDC. Functional insulation between outputs and case. Functional insulation between outputs. Pollution degree environment (AC-input) and degree (DC input). CB Scheme is available (SE-9). The converters are subject to manufacturing surveillance in accordance with the above mentioned UL standards and with ISO900:000. For details see the Declaration of Conformity (last pages). Railway Applications All W Series converters have been designed observing the railway standards EN 5055 and EN 50. All boards are coated with a protective lacquer. The EW Series is particularily suitable for connection to 0 V railway batteries. Protection Degree The protection degree of the converters is IP 0. Protective covers over input and output terminals are available on request; see Accessories. Cleaning Agents Any penetration of liquid or foreign solid objects is to be prevented, since the converters are not hermetically sealed. BCD000-G REV AA Page 9 of 8

Power-One will not honor any warranty claims resulting from electric strength field tests. Leakage Currents in AC-DC Operation Leakage currents flow due to internal leakage capacitance and RFI suppression Y-capacitors. The current values are proportional to the mains voltage and nearly proportional to the mains frequency. They are specified at maximum operating input voltage where phase, neutral, and protective earth are correctly connected as required for class I equipment. Leakage current may exceed.5 ma, if f i > 6 Hz. Safety of Operator-Accessible Output Circuits If the output circuit of a converter is operator accessible, it shall be a SELV circuit according to IEC/EN related safety standards. The converters have SELV output circuits up to an output voltage of 57.5 V. However, if the isolated outputs are connected to another voltage source or connected in series with a total of >57.5 V the outputs are hazardous. It is the sole responsibility of the installer to ensure the compliance with the relevant and applicable safety regulations. LED Indicator A green LED is activated, when the output voltage V o is within the normal operating tolerance band. Note: This LED is also activated, when the converter is not powered by the input, but a loaded battery is connected to the output. BCD000-G REV AA Page 0 of 8

22 5, 50 Watt AC-DC and DC-DC DIN-Rail Converters D: Output Voltage Monitor D is intended for monitoring the bus voltage of a batterybuffered system. It indicates that the system is powered from the battery and can for instance be used as warning signal or to switch off a part of the load. If the output voltage drops below V o low D, the D signal (open-collector) goes to high impedance. I D max <50 ma. The D output is protected by a Zener diode against transients up to 75 V (for models with V o max >50 V up to 90 V). In double-output models D monitors only output. In applications without battery-buffering the D signal may not be suitable, since smaller dynamic load changes may cause D to trigger. For such applications D5 with a trigger level of approx. 85% V o nom should be chosen (e.g., for bus voltage.7 V, trigger level at V). Table 7: Options D and D5 - trigger and switch-on levels Model Battery V o low D V o low D 5 V Bat trigger switch on trigger switch on [V] [V] [V] [V] [V] LWR/LWN LWR/LWN0... LWR/LWN LWR/LWN LWN D5: System Voltage Monitor (Battery Deep) D5 monitors the output voltage V o (V o in double-output models) or the lowest admissible voltage of a connected battery (battery deep discharge). The definition of D5 is similar to D, but the trigger level is lower. When V o drops below the value specified in the table below, the D5 signal (opencollector) goes to high impedance. I D max < 50 ma. The D5 output is protected by a Zener diode against transients up to 75 V (for models with V o max >50 V up to 90 V). In systems without battery support, D5 signals that V o (or V o ) is going to drop below a safe value. In battery-buffered systems, D5 indicates that the battery has reached its deepest discharge level prior to getting damaged. The D5 signal can be used for instance to disable loads, save data, or to start a controlled switch-off of running processes. Adjustment of Threshold Levels (D/D5) Pin 7 of the D-SUB connector allows for adjustment of the threshold levels of D and D5. Both levels are influenced by the voltage divider Rx / Ry. Resistor Rx to pin (VCC) lowers the levels, whereas Ry to pin (GND) increases them (see fig. ). Option S: Shutdown Reduces the output power to approx. W, i.e., the converter is not fully disabled. In a no-load condition V o drops below 6. V; see fig..

A built-in second fuse in the neutral line provides safe phaseto-phase connection at low mains voltages (e.g., USA 0 V/ 08 V /60 Hz systems). The built-in second fuse also enables safe connection to the mains, where phase and neutral are not defined or cannot be identified, as e.g., in the case of plug and socket connection to the mains via German Schuko-plugs; see also Safety and Installation Instructions. Option F limits the DC input voltage to 50 V. Option Q: Reverse Polarity Protection EW models have no bridge rectifier at the input. To provide reverse polarity protection, an additional diode can be fitted. However this lowers the efficiency by approximately %. Option K: System Connectors For installation in systems using pre-assembled harnesses the converters are available with system connectors. They are ULlisted, approved for currents up to 5 A at 0 to 05 C. The mating system connectors with screw terminals and retainers are delivered together with every converter with option K.

Note: If longer wires are used to connect the R input at the D-SUB connector, the wiring to pin (GND) should be done as star point connection. If wired differently, the output voltage setting may be adversely affected. In battery charging systems, an external battery temperature sensor (see Accessories) can be connected to optimize V o.
