(Pending)

The SC60B Series operate over

an ultra wide input range of 9-36

Vdc or 18-76 Vdc. Efficiencies

greater than 89% over the entire input

range are typical. Additional features

include higher ambient operating

temperatures, reduced airflow require-

ments, excellent regulation and tran-

sient response characteristics. Single

board package with industry standard

footprint. Designed for through hole

mounting.

Applications

These units are ideally suited for

telecommunications mobile/optical

switches, network routers and systems

requiring distributed power architecture.
