Series Description
The MGDM-160 high input series is a complete line of high density wide input range DC/DC power modules designed for aerospace, military and high-end industrial applications. These modules use a patented fixed switching topology at 500 KHz providing wide input range, low noise characteristics and high power density. Standard models are available with wide input voltage range of 180-480 volts. The series include single output voltage of 5, 12, 15, 26 volts.
The MGDM-160 high input series include synchronization, parallelable with load sharing, trim and sense functions.
The synchronization function allows to synchronize more than one converter to one frequency or an external source frequency.
The parallelable function allows increased power with a true N+1 redundancy.
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple.
The modules have totally independant security functions including input undervoltage lock-out, output overvoltage protection, output current limitation protection, and temperature protection.
Additionnally a soft-start function allows current limitation and eliminates inrush current during start-up.
The design has been carried out with surface mount components, and is manufactured in a fully automated process to guarantee high quality. The modules are potted with a bi-component thermal conductive compound to ensure optimum power dissipation under harsh environmental conditions.
