Description
The FC250R Power Module is a dc-dc converter that operates over an input voltage range of 18 Vdc to 36 Vdc
and provides a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile
polarity configurations and grounding connections. The module has a maximum power rating of 250 W at a typ-
ical full-load efficiency of 88%.
Two or more modules may be paralleled with forced load sharing for redundant or enhanced power applications.
The package, which mounts on a printed-circuit board, accommodates a heat sink for high-temperature
applications.
