1 28 Wa AC-DC Converers Feaures RoHS lead-free-solder and lead-solder-exemped producs are available. Class I equipmen Power facor >.93, harmonics IEC/EN Immuniy according o IEC/EN 6-4-2, -3, -4, -, -6, -8, -9 Complian wih EN, EN 2-4, EN 44. High efficiency Inpu over- and undervolage lockou Adjusable oupu volage wih remoe on/off or 2 oupus: SELV, no load, overload, and shor-circui proof Recangular curren limiing characerisic PCBs proeced by lacquer Very high reliabiliy 4.4" 3 U Safey-approved according o IEC/EN 69-, UL/CSA 69-2 nd Ed " 6 TE " Descripion The LK4/ Series of AC-DC converers represens a flexible range of power supplies for use in advanced elecronic sysems; he LKP models are an exension wih increased oupu power, bu opimized o 23 VAC. Feaures include full power facor correcion, good hold-up ime, high efficiency and reliabiliy, low oupu noise, and excellen dynamic response o load/line changes. The converers are proeced agains surges and ransiens occurring a he source lines. Inpu over- and undervolage lockou circuiry disables he oupus, when he inpu volage is ouside of he specified range. Inpu inrush curren limiaion is included for prevening circui breakers and fuses from ripping a swich-on. All oupus are overload, open- and shor-circui proof, and proeced by a buil-in suppressor diode. The oupus can be inhibied by a logic signal applied o connecor pin 8. If he inhibi funcion is no used, pin 8 mus be conneced wih pin 4 o enable he oupus. LED indicaors display he saus of he converer and allow 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 and buil according o he inernaional safey sandards IEC/EN 69-2 nd Ed. They have been approved by safey agencies. 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 9 C under all condiions. However, higher oupu power up o 28 W is possible depending on environmenal condiions and converer model.

4 28 Wa AC-DC Converers Funcional Descripion The inpu volage is fed via an inpu fuse, an inpu filer, a recifier, and an inrush curren limier o he boos converer. This sep-up converer provides a sinusoidal inpu curren (IEC/EN 6-3-2, class D equipmen) and charges he bulk capacior C b o approx. 37 VDC. This capacior sources a single-ransisor forward converer and provides he power during he hold-up ime. The main ransformer exhibis a separae secondary winding for each oupu. Each generaed volage is recified and smoohed by he power choke and he oupu filer. The conrol logic senses he main oupu volage V o or 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. A separae auxiliary converer generaes he supply volages for all primary and secondary conrol circuis and opions.

11 28 Wa AC-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 (applied o -7 or -9) models allows T A o be higher han 7 C (e.g., 8 C), if T C max is no exceeded. Deails are specified in fig. 2, including - and -6 models. I o /I o nom convecion cooling - forced cooling T A C Fig. 2 Oupu curren deraing versus emperaure for -, -6, and -9 (or -7) models. 43b T C max Oupu Proecion Each oupu is proeced by a suppressor diode agains overvolage, which could occur due o a failure of he conrol circui. In such a case, he suppressor diode becomes a shor circui. The suppressor diodes may smooh shor overvolages resuling from dynamic load changes, bu hey are no designed o wihsand exernally applied overvolages. A shor circui a any of he wo oupus will cause a shudown of he oher oupu. A red LED indicaes any 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 or Series Connecion of Converers Single- or double-oupu models wih equal oupu volage can be conneced in parallel wihou any precauions 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. Series connecion of oupus oalizing more han 36 V nominal volage need addiional measures o limi he oupu o 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. Thermal Proecion A emperaure sensor generaes an inernal inhibi signal, which disables he oupus, when he case emperaure exceeds T C max. The oupus auomaically recover, when he emperaure drops below his limi. Coninuous operaion under simulaneous exreme worscase condiions of he following hree parameers should be avoided: Minimum inpu volage, maximum oupu power, and maximum emperaure.
