MGDDI-06 Series 6 W Ultra-Wide Input DC/DC Converters

Gaia Converter's MGDDI-06 series ultra-wide input DC/DC power modules offer a permanent ultra-wide input voltage range of 12 V to 160 V. This series is designed for distributed power architectures where variable input voltage and transient are prevalent, making them ideal applications such as railway and transportation systems, avionics, and military. The MGDDI-06 series is compliant with railway 24 V_DC, 37 V_DC, 72 V_DC, and 110 V_DC voltage ranges or DO-160/MIL-STD-704 voltage ranges without an additional voltage limiter.

The series includes dual output voltage choices individually isolated of 2 V x 5 V, 2 V x 12 V, 2 V x 15 V, and 2 V x 24 V. These can be easily configured in parallel, series, symmetrical, or independent. The total power is 6 W and the two outputs can be used with unbalance up to 5 W on one channel and 1 W on the other.

The modules are designed with an LC network filter to minimize reflected input current ripple. The MGDDI-06 devices include a soft-start, an input under-voltage 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 converters against short-circuits of any duration by shut-down and restores to normal when the overload is removed. The modules are potted with a bicomponent thermal conductive compound to ensure optimum power dissipation under harsh environmental conditions.
