Series Description
The MGDI-35 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 technic at 250 KHz providing excellent reliability, low noise characteristics and high power density. Standard models are available with wide input voltage range of 9-36, 18-75 and 36-140 volts. The serie includes single, bi and triple output voltage choices of 3.3, 5, 12, 15 volts.
No external heatsink is required for the MGDI-35 series to supply 35 W output power over the full temperature range.
The MGDI-35 serie is designed in conformity with safety standards EN60950 and UL1950. 
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple according to EN55022 and FCC Part 15J standard.
The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit protection and an output overvoltage protection 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 modules against short-circuits of any duration by a shut-down and restores to normal when the overload is removed.
The design has been carried out with surface mount components and is manufactured in a fully automated process to guarantee high quality. Each module is tested with a GAIA Converter automated test equipment.
