Series Description
The MGDDI-20 ultra wide input series designates a full family of DC/DC power modules designed for use in distributed power architecture where variable input voltage for multiple battery and transient are prevalent making them ideal particularly for transportation/mass transit, railways or high-end industrial applications. These modules use a high frequency fixed swiching topology at 270 KHz providing excellent reliability, low noise characteristics and very high efficiency over the entire input voltage range.
Standard models are available with a permanent ultra wide input voltage range of 12-160 volts fully compatible with 24 V / 36 V / 72 V / 110 V / 125 V battery applications. The serie includes dual output voltage choices individually isolated of 2 x 5 volts , 2 x 12 volts, 2 x 15 volts and 2 x 24 volts with easy configurability.
The MGDDI-20 serie is designed in conformity with safety standards EN60950.
All the modules are designed with LC network filters to minimize reflected input current ripple according to ease EN55022 standard.
The modules include a soft-start, an input undervoltage lock-out, a permanent short circuit protection and an output overvoltage limitation 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.
