Description

The MGDD-40 ultra wide input series designates a full family of DC/DC power modules with a permanent ultra wide input voltage range of 9-60 or 4.5-33volts 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-40 is designed for applications where high power density as high as 60W per cubic inch.The MGDD-40 series is compliant with DO160 and MIL-STD-704 transient voltage without additional voltage limiter.

The series includes dual output voltage choices individually isolated of 2x3.3 volts, 2 x 5 volts , 2 x 12 volts, 2 x 15 volts and 2 x 24 volts with easy configurability.

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 protection and an output overvoltage limitation to ensure efficient module protections. The soft-start allows current limitation and eliminates inrush current during startup. 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.

Gaia's MGDD-40 Series of High-Reliability DC-DC Converters are designed for higher operating temperatures of -40 to +105°C (optional -55°C) with input ranges required for typical military & airborne applications.

All Hi-Rel models come standard with On/Off function (/M option only for Industrial models).

Available Options (see specs for details):
• T = -55°C Start-Up Temperature
• S = Screening & Serialization
