These units are ideally suited for
telecommunications and applications
having a widely varying input voltage
such as automotive test equipment,
process control, minicomputers and
geosurvey equipment.
Applications
he 50-Watt FM series offer single
and triple outputs, high efficiency
and low cost. These converters
were designed for rugged environ-
ments. Internal filtering is provided to
reduce the magnitude of the reflected
ripple current. Single output models
can be used in parallel for higher power
applications. The FM series is pack-
aged in a 4.0” x 2.6” x 0.5” six-sided
shielded case.
