Description

The MGDM-250 wide input series is a complete family of DC/DC power modules designed for use in distributed power architecture where variable imput voltage and transient are prevalent. Designed for aerospace, military and high-end industrial applications.

Ideal with wide input voltage range of 9-36 Vdc and single output voltage of 5, 12, 15 or 24 volts, these modules use high frequency fixed switching topology at 330KHz providing excellent reliability, easing noise management, and high power density.

All the modules are designed with LC network filters to minimize reflected input current ripple and voltage ripple. The modules have independant security functions including input undervoltage lock-out, output overvoltage protection, output current limitation protection, and temperature protection. The soft-start function allows current limitation and eliminates inrush current during start-up. The modules are potted with a bi-component thermal conductive compound and used an insulated metallic substrat to ensure optimum power dissipation under harsh environmental conditions.
