Gaia Converter MGDSI-254-H-E

The MGDI-254 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 switching topology at 330KHz 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 choice of 12 volts or 15Volts. The MGDI-254 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 use an insulated metallic substrat to ensure optimum power dissipation under harsh environmental conditions.
