Series Description
The MGDM-26 series is a complete line of DC/DC power modules designed for aerospace, military and high-end industrial applications. 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 standard input voltage range of 9-36 or 16-40 volts. The series include single output voltage choices of 3.3, 5, 12, 15 volts.
The MGDM-26 series include synchronization and load sharing functions.
The synchronization function allows to synchronize more than one converter to one frequency or an external source frequency. The load sharing allows parallel operation to increase power with a true N+1 redundancy.
All the modules are designed with LC network filters to minimize reflected input current ripple and output voltage ripple.
The modules include a soft-start, an input undervoltage 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. The modules are potted with a bi-component thermal conductive compound and package in a metallic case to ensure the module's integrity under high environmental conditions.
