Six-sided shielding
The 30 Watt SC30N series
operates over a wide input range
of 18-36 Vdc or 36-75 Vdc.
Efficiencies of 83% are typical over
varying load conditions of 25% to
100%. Additional features include input
reverse polarity protection, remote
on/off control, logic compatible with
CMOS or open collector TTL, short
circuit protection with auto restart,
overvoltage protection, and an operat-
ing range of -40°C to +100°C case
temperature with no derating. Units are
packaged in a six-sided continuous
shielded case for EMI/RFI protection
and measure 2.5” x 3.0” x 0.5”.
Applications
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.
