Six-sided shielding
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 18-Watt TA series operates
over an ultra wide input range of
9-36 Vdc or 20-72 Vdc. Efficien-
cies of 77% 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 operating tempera-
ture range of -25°C to +71°C 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 0.83”.
