1-General

nnThe MGDM-150 high input voltage series is acomplete line of high density wide input rangeDC/DC power modules designed for aerospace,military and high-end industrial applications.
These modules use a patented fixed switchingtopology at 210 KHz providing ultra wide inputrange, low noise characteristics and high power
density. Standard models are available with ul-tra wide input voltage range of 120-480 volts.The series include single output voltage choices
of 3,3, 5, 12, 15, 24, 28 volts.The MGDM-150 high input voltage series include,trim and sense functions synchronization andload sharing.The synchronization function allows to
synchronize more than one converter to onefrequency or an external source frequency. Theload sharing allows parallel operation to
increase power with a true N+1 redundancy.
All the modules are designed with LC networkfilters to minimize reflected input current rippleand output voltage ripple.
The modules have totally independant securityfunctions including input undervoltage andovervoltage lock-out, output overvoltage protec-
tion, output current limitation protection, andtemperature protection. Additionnally a soft-startfunction allows current limitation and eliminates
inrush current during start-up.The design has been carried out with surfacemount components, planar transformer and is
manufactured in a fully automated process toguarantee high quality. The modules are pottedwith a bi-component thermal conductive compound
and used an insulated metallic substrate to ensureoptimum power dissipation under harshenvironmental conditions. nn4 nn
