Description
The FW250H1 and FW300H1 Power Modules are dc-dc converters that operate over an input voltage range of
36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the inputs,
allowing versatile polarity configurations and grounding connections. The modules have maximum power rat-
ings from 250 W to 300 W at a typical full-load efficiency of 89%.
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.
