1 Wa DC-DC and AC-DC Converers Feaures RoHS lead-free-solder and lead-solder-exemped producs are available. Complian wih EN, EN --, EN. Class I equipmen Exremly wide inpu volage ranges from 8 o 8 VDC, and 8 o 6 VAC, 7 o Hz Inpu over- and undervolage lockou Adjusable oupu volage wih remoe on/off or oupus: SELV, no load, overload, and shorcircui proof Recangular curren limiing characerisic PCBs proeced by lacquer Very high reliabiliy." U Safey-approved according o IEC/EN 69-, UL/CSA 69- nd Ed. 8." 6 TE " Descripion The K Series of DC-DC and AC-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. LK 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 swichon. All oupus are open- and shor-circui proof, and are proeced agains overvolages by means of buil-in suppressor diodes. The oupu can be inhibied by a logic signal applied o pin 8 (i). The 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 o oupu isolaion is provided. The converers are designed, buil, and safey-approved o he inernaional safey sandards IEC/EN 69-. They are pariculary suiable for railway applicaions and comply wih EN and EN --. The case design allows operaion a nominal load up o 7 C wih naural cooling. If forced cooling is provided, he ambien emperaure may exceed 7 C, bu he case emperaure mus remain below 9 C. A emperaure sensor generaes an inhibi signal, which disables he oupus when 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 " DIN-rack sysem according o IEC 697-, or be chassis mouned. Imporan: For applicaions requiring compliance wih IEC/EN 6-- (harmonic disorion), please use our LK or LK Series wih incorporaed power facor correcion (PFC). Table of Conens Page Page Descripion...

4 Wa DC-DC and AC-DC Converers Funcional Descripion The inpu volage is fed via an inpu fuse, an inpu filer, a bridge recifier (LK models only), and an inrush curren limier o he inpu capacior. This capacior sources a singleransisor forward converer wih a special clamping circui and provides also he power during he hold-up ime. 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 an 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 swiching ransisor of he forward converer. The second oupu of double-oupu models is racking he main oupu, bu has is own curren limiing circui. If he main oupu volage drops due o curren limiaion, he second oupu volage will fall as well and vice versa. Sandard models wih a single. V oupu have a synchronos recifier o provide good efficiency.

6 Wa DC-DC and AC-DC Converers Inpu Transien Proecion A suppressor diode or a VDR (depending upon he inpu volage range) ogeher wih he inpu fuse and a symmerical inpu filer form an effecive proecion agains high inpu ransien volages which, ypically occur in mos insallaions, bu especially in baery-driven mobile applicaions. Sandard nominal baery volages are:,, 6, 8, 6, 7,, and V. Railway baeries are specified wih a olerance of % o +%, wih shor excursions up o ±%. In cerain applicaions, addiional surges according o RIA are specified. The power supply mus no swich off during hese surges, and since heir energy can pracically no be absorbed, an exremely wide inpu range is required. The EK inpu range for V baeries has been designed and esed o mee his requiremen. Inrush Curren Limiaion The CK, DK, EK, and LK models incorporae an NTC resisor in he inpu circuiry, which a iniial urn-on reduces he peak inrush curren value by a facor of, such proecing connecors and swiching devices from damage. Subsequen swich-on cycles wihin shor periods will cause an increase of he peak inrush curren value due o he warming-up of he NTC resisor. See also Opion E. The inrush curren peak value (iniial swich-on cycle) can be deermined by following calculaion; see also fig. : V i source I inr p = (R s ex + R i + R NTC ) R s ex I inr p R i R NTC 9a Inpu Fuse A fuse mouned inside he converer proecs agains severe defecs. This fuse may no fully proec he converer, when he inpu volage exceeds VDC.

However, he relaionship beween T A and T C depends heavily upon 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., 8 C), as long as T C max is no exceeded. Deails are specified in fig. 8. I o /I o nom Convecion cooling Forced cooling 89a T C max applied overvolages. Overload a any of he oupus will cause a shu-down of all oupus. A red LED indicaes he overload condiion. Noe: V o BR is specified in Elecrical Oupu Daa. If his volage is exceeded, he suppressor diode generaes losses and may become a shor circui. Parallel and Series Connecion Single- or double-oupu models wih equal oupu volage can be conneced in parallel using opion T (curren sharing). If he T pins are inerconneced, all converers share he oupu curren equally. Single-oupu models and/or main and second oupus of double-oupu models can be conneced in series wih any oher (similar) oupu. Noes: Parallel connecion of double-oupu models should always include boh, main and second oupu o mainain good regulaion. No more han converers should be conneced in parallel. Series connecion of second oupus wihou involving heir main oupus should be avoided, as regulaion may be poor.

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 opencollecor oupu should be placed on he VME back plane. Afer he ACFAIL signal has gone low, he VME sandard requires a hold-up ime h of a leas ms, before he. V oupu drops o.87 V, when he oupu is fully loaded. This hold-up ime h is provided by he inernal inpu capaciance. Consequenly he working inpu volage and he hreshold level V i should be adequaely above V i min of he converer, so ha enough energy is remaining in he inpu capaciance.
