Series Description
The MGDD-80 ultra wide input series designates a full family of DC/DC power modules with a permanent ultra wide input voltage range of 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-80 is ideal for applications where high power density up to 50 W/inch3 is required.
The MGDD-80 series is compliant with DO-160 and MIL-STD-704 transient voltage without additional voltage limiter.
The serie 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  2 x 24, and 5 and 12 volts all wih easy configuration in series,parallel, symmetry.
The total power is 80 W with one single channel able to provide up to 75 W in load unbalanced mode. 
All the modules are designed with LC network filters 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 thermally conductive compound to ensure optimum power dissipation under harsh environmental conditions.
