Product Description
Safety Extra Low Voltage (SELV) 48.0 V Nominal Output
4242 Vdc isolation
The DCM Isolated, Regulated DC Converter is a DC-DC
ZVS high frequency switching
converter, operating from an unregulated, wide range input to
generate an isolated 48.0 Vdc output. With its high frequency
n Enables low-profile, high-density filtering
zero voltage switching (ZVS) topology, the DCM converter
Optimized for array operation
consistently delivers high eciency across the input line range.
Modular DCM converters and downstream DC-DC products
n Up to 8 units 4000 W
support ecient power distribution, providing superior power
n No power derating needed
system performance and connectivity from a variety of
n Sharing strategy permits dissimilar line voltages
unregulated power sources to the point-of-load.
