1 Wa AC-DC and DC-DC Converers 6." TE "." 3 U Feaures Inpu volage ranges from 8 o 385 VDC and 85 o 6 VAC, 7- Hz or isolaed oupus up o 8 VDC Class I equipmen RoHS lead solder exempion complian Exremely-wide inpu volage range Inpu over- and undervolage lockou Efficien inpu filer and buil-in surge and ransien suppression circuiry Oupus: SELV, no-load, and shor-circui proof No deraing over enire operaing emperaure range PCBs coaed wih proecive lacquer Very high reliabiliy Safey according o IEC/EN 695 Descripion The S Series AC-DC and DC-DC converers represens a broad and flexible range of power supplies for use in advanced elecronic sysems. Feaures include high efficiency, high reliabiliy, low oupu volage noise and excellen dynamic response o load/line changes. LS models can be powered by DC or AC wih a wide-inpu frequency range (wihou PFC). The converer inpus are proeced agains surges and ransiens. An inpu over- and undervolage lockou circuiry disables he oupus if he inpu volage is ouside of he specified range. Cerain ypes include an inrush curren limier prevening circui breakers and fuses from ripping a swich-on. All oupus are open- and shor-circui proof and are proeced agains overvolages by means of buil-in suppressor diodes. The oupus can be inhibied by a logic signal applied o pin 8 (i). If he inhibi funcion is no used, pin 8 mus be conneced wih pin o enable he oupus. LED indicaors display he saus of he converer and allow for visual monioring of he sysem a any ime. Full inpu-o-oupu, inpu-o-case, oupu-o-case and oupu-ooupu isolaion is provided. The converers are designed and buil according o he inernaional safey sandards IEC/EN 695 and EN555. They have been approved by he safey agencies TÜV and UL (for USA and Canada). The case design allows operaion a nominal load up o 7 C in a free-air ambien emperaure. If forced cooling is provided, he ambien emperaure may exceed 7 C, bu he case emperaure mus remain below 95 C under all condiions. A emperaure sensor generaes an inhibi signal, which disables he oupus if he case emperaure T c exceeds he limi. The oupus are auomaically re-enabled when he emperaure drops below he limi. Various opions are available o adap he converers o individual applicaions. The converers may eiher be plugged ino a 9" rack sysem according o IEC 697-3, or be chassis mouned. They are ideally suied for Railway applicaions. Imporan: For applicaions requiring compliance wih IEC/EN 6-3- (harmonic disorion), please use our LS and LS5 Series wih incorporaed power facor correcion (PFC). Table of Conens Page Descripion...

4 Wa AC-DC and DC-DC Converers Funcional Descripion The inpu volage is fed via an inpu fuse, an inpu filer, a bridge recifier (LS), and an inrush curren limier o he inpu capacior. This capacior sources a single ransisor forward converer. Each oupu is powered by a separae secondary winding of he main ransformer. The resulan volages are recified and heir ripple smoohed by a power choke and oupu filer. The conrol logic senses he main oupu volage V o and generaes, wih respec o he maximum admissible oupu currens, he conrol signal for he primary swiching ransisor. The second oupu of double-oupu models is conrolled by he main oupu bu has independen curren limiing. If he main oupu is driven ino curren limiaion, he second oupu volage will fall as well and vice versa.

10 Wa AC-DC and DC-DC Converers Thermal Consideraions If a converer is locaed in free, quasi-saionary air (convecion cooling) a he indicaed maximum ambien emperaure T A max (see able: Temperaure specificaions) and is operaed a is nominal inpu volage and oupu power, he emperaure measured a he Measuring poin of case emperaure T C (see: Mechanical Daa) will approach he indicaed value T C max afer he warm-up phase. However, he relaionship beween T A and T C depends heavily on he condiions of operaion and inegraion ino a sysem. The hermal condiions are influenced by inpu volage, oupu curren, airflow and emperaure of surrounding componens and surfaces. T A max is herefore, conrary o T C max, an indicaive value only. Cauion: The insaller mus ensure ha under all operaing condiions T C remains wihin he limis saed in he able Temperaure specificaions. Noes: Sufficien forced cooling or an addiional hea sink allows T A o be higher han 7 C (e.g., 85 C) if T C max is no exceeded. For -7 or -9 models a ambien emperaure T A = 85 C wih only convecion cooling, and he maximum permissible curren for each oupu is approx. % of is nominal value as per he figure below I o /I o nom.3.. T A min Convecion cooling Forced cooling _535 T C max Fig. 7 Oupu curren deraing versus emperaure for -7 and -9 models. T A [ C] Thermal Proecion A emperaure sensor generaes an inernal inhibi signal which disables he oupus if he case emperaure exceeds T C max. The oupus are auomaically re-enabled when he emperaure drops below his limi. Coninuous operaion under simulaneous wors-case condiions of he following hree parameers should be avoided: minimum inpu volage, maximum oupu power, and maximum emperaure. Oupu Proecion Each oupu is proeced agains overvolages which could occur due o a failure of he inernal conrol circui. Volage suppressor diodes (which under wors case condiion may become a shor circui) provide he required proecion. The suppressor diodes are no designed o wihsand exernally applied overvolages. Overload a any of he oupus will cause a shu-down of all oupus. A red LED indicaes he overload condiion. Parallel or Series Connecion Single or double-oupu models wih equal nominal oupu volage can be conneced in parallel wihou any precauions using Opion T (curren sharing). Single oupu models and/or main and second oupus of doubleoupu models can be conneced in series wih any oher (similar) oupu. Noes: Parallel connecion of double oupu models should include boh, main and second oupu o mainain good regulaion of boh oupus. No more han 5 models should be conneced in parallel. Series connecion of second oupus wihou involving heir main oupus should be avoided as regulaion may be poor. Raed oupu volages above 36 V need addiional measures in order o comply wih he safey requiremens for SELV (Safe Exra Low Volage) The maximum oupu curren is limied by he oupu wih he lowes curren limiaion if several oupus are conneced in series.

29 Wa AC-DC and DC-DC Converers Opion V: ACFAIL Signal (VME) Available only for models wih V o = 5. V. This opion defines an undervolage monioring circui for he inpu and main oupu volage. I generaes an ACFAIL signal (V signal) which conforms o he VME sandard. The low sae level of he ACFAIL signal is specified a a sink curren of I V 8 ma o V V.6 V (open-collecor oupu of an NPN ransisor). The pull-up resisor feeding he open-collecor oupu should be placed on he VME backplane. Afer he ACFAIL signal has gone low, he VME sandard requires a hold-up ime ( h) of a leas ms before he 5. V oupu drops o.875 V when he oupu is fully loaded. The hold-up ime is provided by he inernal inpu capaciance. Consequenly, he working inpu volage and he hreshold level (V i) should be adequaely above he minimum inpu volage (V i min) of he converer so ha enough energy is remaining in he inpu capaciance. If he inpu volage is below he required level, an exernal hold-up capacior (C i ex ) should be added. Formula for hreshold level for desired value of h : P o ( h +.3 ms) V i = + V i min C i min η Formula for he exernal inpu capacior: P o ( h +.3 ms) C i ex = C i min η (V i Vi min ) where as: C i min = inernal inpu capaciance [mf] C i ex = exernal inpu capaciance [mf] P o = oupu power [W] η = efficiency [%] h = hold-up ime [ms] V i min = minimum inpu volage [V] V i = hreshold level [V] Min. inpu volage according o Elecrical Inpu Daa. For oupu volages V o > V o nom, he minimum inpu volage increases proporionally o V o /V o nom. Remarks: Opion V and V3 can be adjused by poeniomeer o a hreshold level beween V i min and V i max. A decoupling diode should be conneced in series wih he inpu of AS - FS converers o avoid he inpu capaciance discharging hrough oher loads conneced o he same source volage.
