Description

MGDD-08The MGDD-08 ultra wide input series designates a full family of DC/DC power modules with a permanent ultra wide input voltage range of 4,5-33 volts and 9-60 volts. The family is designed for use in distributed power architecture where variable input voltage and transient are prevalent making them ideal particularly for avionics and military applications.

The MGDD-08 series is compliant with DO-160 and MIL-STD-704 transient voltage without additional voltage limiter.

The series includes dual output voltage choices individually isolated of 2 x 3,3 volts, 2 x 5 volts, 2 x 12 volts, 2 x 15 volts and 2 x 24 volts with easy combination. The total power is 8W with one single channel able to provide up to 6,8W.

All the modules are designed with LC network filter to minimize reflected input current ripple. The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit and overload protection and an output overvoltage limitation to ensure efficient module protections. The soft-start allows current limitation and eliminates inrush current during start-up. The short circuit protection completely protects the modules against short-circuits of any duration by a shut-down and restores to normal when the overload is removed.

The modules are potted with a bi-component thermal conductive compound to ensure optimum power dissipation under harsh environmental conditions.
