Description
The FW150F Power Module is a dc-dc converter that operates over an input voltage range of 36 Vdc to 72 Vdc
and provides a precisely regulated dc output. The output is fully isolated from the input, allowing versatile polar-
ity congurations and grounding connections. The module has a maximum power rating of 99 W at a typical
full-load efciency of 75%.
Built-in ltering, for both the input and output, eliminates the need for external lters. 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.
