1-General
• Galvanic isolation 1.500 VDC
• Integrated LC EMI filter
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 and
overvoltage lock-out, output overvoltage protec-
tion, 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 used an insulated metallic
substrate to ensure optimum power dissipation
under harsh environmental conditions.
The MGDM-150 low input voltage series is a
complete line of high density wide input range
DC/ DC power modules designed for aerospace,
military and high-end industrial applications. These
modules use a patented fixed switching topology
at 420 KHz providing ultra wide input range, low
noise characteristics and high power density. Stan-
dard models are available with ultra wide input
voltage range of 9-45, 16-80 volts. The series
include single output voltage choices of 3,3, 5,
12, 15, 24, 28 volts.
• Synchronizable
•
Load sharing, N+1 redundancy
• No load to full load operation
• Fully protected by independant security
• Under & overvoltage lock-out
• Overvoltage protection
4
• Current limitation protection
• Over temperature protection
• No optocoupler for high reliability
The MGDM-150 low input voltage series include
synchronization load sharing, trim and sense
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.
