1 5 Wa DC-DC (AC-DC) Converers M Series Wide inpu volage from V DC, or 3 isolaed oupus up o 8 V DC kv AC I/O elecric srengh es volage Exremely wide inpu volage range suiable for baery (and AC) operaion Efficien inpu filer and buil-in surge and ransien suppression circuiry Oupus individually isolaed and conrolled Oupus fully proeced agains overload Safey according o IEC/EN 695 LGA Summary The M series of DC-DC (AC-DC) converers represens a broad and flexible range of power supplies for use in advanced indusrial elecronic sysems. Feaures include high efficiency, reliabiliy, low oupu volage noise and excellen dynamic response o load/line changes due o individual regulaion of each oupu. The converer inpus are proeced agains surges and ransiens occuring a he source lines. An inpu over- and undervolage lock-ou circuiry disables he oupus if he inpu volage is ouside he specified range. Cerain ypes include an inrush curren limiaion prevening circui breakers and fuses from being damaged 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 he connecor pin (i). If he inhibi funcion is no used pin should be conneced o pin 3 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 modules are designed and buil according o he inernaional safey sandard IEC/EN 695 and have been approved by he safey 39.5" 8TE ".37" 3U agencies LGA (Germany) and UL (USA). The UL Mark for Cana-da has been officially recognized be regulaory auhoriies in provinces across 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 should 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 modules may eiher be plugged ino 9 inch rack sysems according o DIN 9, or be chassis mouned.

4 Funcional Descripion The inpu volage is fed via an inpu fuse, an inpu filer, a recifier 3 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 ripples smoohed by a power choke and an oupu filer. The conrol logic senses he main oupu volage U o and generaes, wih respec o he maximum admissible oupu currens, he conrol signal for he primary swiching ransisor. This signal is fed back via a coupling ransformer. The auxiliary oupus U o and U o3 are individually regulaed by means of secondary swiching ransisors. Each auxiliary oupu's curren is sensed using a curren ransformer. If one of he oupus is driven ino curren limi, he oher oupus will reduce heir oupu volages as well because all oupu currens are conrolled by he same main conrol circui.

6 Inpu Fuse A fuse holder conaining a slow-blow ype fuse (Dimension: 5 mm) is mouned in he converer's back plae. The fuse proecs he module agains severe defecs.

In applicaions where he converers operae a DC source volages above V DC, an exernal fuse or a circui breaker a sysem level should be insalled. For applicaions where he fuse should be inaccessible: see Opion F. Inpu Under-/Overvolage Lock-ou If he inpu volage remains below.8 U i min or exceeds.u i max (approx. values), an inernally generaed inhibi signal disables he oupu(s). When checking his funcion he absolue maximum inpu volage raing U i abs mus be carefully considered (see able: Inpu daa).

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.

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 if he emperaure drops below his limi. 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 of he respecive oupu. Parallel and Series Connecion Main oupus of equal nominal volage can be conneced in parallel. I is imporan o assure ha he main oupu of a muliple oupu module is forced o supply a minimum curren of. A o enable correc operaion of is own auxiliary oupus. In parallel operaion, one or more of he main oupus may operae coninuously in curren limiaion which will cause an increase in case emperaure. Consequenly, a reducion of he max. ambien emperaure by K is recommended. Main or auxiliary oupus can be conneced in series wih any oher oupu of he same or anoher module. In series connecion, he maximum oupu curren is limied by he lowes curren limi. Oupu ripple and regulaion values are added. Connecion wiring should be kep as shor as possible. If oupu erminals are conneced ogeher in order o esablish muli-volage configuraions, e.g. +5. V, ± V ec. he common ground connecing poin should be as close as possible o he connecor of he converer o avoid excessive oupu ripple volages. Auxiliary oupus should never be conneced in parallel!

9 Oupu Curren Allocaion for Special Types Oupu currens differing from hose given for sandard ypes (as per: Type Survey and Key Daa) can be provided. A maximum oupu power of 5 W should be considered, if an ambien emperaure range of C is required. The maximum permissible oupu currens are indicaed in he able below. If (upon cusomer's reques) oupu volages are differen from sandard values, he relevan oupu currens have o be adaped accordingly.

23 V ACFAIL Signal (VME) Available for unis wih U o = 5. V. This opion defines an undervolage monioring circui for he inpu or he inpu and main oupu volage equivalen o opion D and generaes he 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 U V.6 V (open-collecor oupu of a 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 5. V 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 U i should be adequaely above he minimum inpu volage U imin 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 : Formula for addiional exernal inpu capacior P o ( h +.3 ms) C i ex = C i min η (U i U i min ) where as: C i min = minimum inernal inpu capaciance [mf], according o he able below C i ex = exernal inpu capaciance [mf] P o = oupu power [W] η = efficiency [%] h = hold-up ime [ms] U i min = minimum inpu volage [V] U i = hreshold level [V] Remarks: The hreshold level U i of opion V and V3 is adjused during manufacure o a value according o he able below. A decoupling diode should be conneced in series wih he inpu of AM, BM, CM, DM and FM converers o avoid he inpu capaciance discharging hrough oher loads conneced o he same source volage.

24 Threshold olerances and hyseresis: If U i is moniored, he inernal inpu volage is measured afer he inpu filer and recifier (EM, LM and LMZ ypes). Consequenly his volage differs from he volage a he connecor pins by he volage drop U i across inpu filer and recifier. The hreshold level of opion V is facory adjused a I o nom and T A = 5 C. The value of U i depends upon he inpu volage range (AM, BM,...), hreshold level U i, emperaure and inpu curren. The inpu curren is a funcion of inpu volage and oupu power.
