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 TUC/TUM Series
operates over an ultra wide input
range of 9-36 Vdc or 20-72 Vdc.
Efficiencies of 77% are typical over
varying load conditions of 25% to
100%. Additional features include input
reverse polarity protection, short circuit
protection with auto restart, overvoltage
protection, and an operating tempera-
ture range of –25°C to +71°C with no
derating.
