Series Description
The MGDI-124 wide input series is a full family of DC/DC power modules designed for use in distributed power architecture where variable input voltage and transient are prevalent making them ideal particularly for transportation, railways or high-end industrial applications. These modules use a high frequency fixed swiching topology at 330 KHz providing excellent reliability, low noise characteristics and high power density. Standard models are available with wide input voltage range of 9-36 volts. The serie includes single output voltage choices of 5, 12, 15 and 24 volts.
The MGDI-124 series include trim and sense functions.
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple.
The modules have totally independant security functions including input undervoltage lock-out, output overvoltage protection, output current limitation protection, and temperature protection. Additionnally a soft-start function allows current limitation and eliminates inrush current during start-up.
The design has been carried out with surface mount components, planar transformer and is manufactured in a fully automated process to guarantee high quality. 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.
