Series Description
The MGDI-26 series is a complete line of DC/DC power modules designed for use in distributed power architecture and are particularly suitable for mobile or ground fixed applications in transportation, industrial and telecommunication areas. These modules use a high frequency fixed swiching technic at 1 MHz providing excellent reliability, low noise characteristics and high power density. Standard models are available with wide input voltage range of 9-36 or 16-40 volts. The series include single output voltage choices of 3.3, 5, 12 and 15 volts.
The MGDI-26 series 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 undervoltazge lock-out and a permanent short
circuit 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. Every module is tested with a GAIA converter automated test equipment.
