The 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.

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.

NOTES:

1. Ripple measured with a 3.3 mf tantalum capacitor

across each output.

2. Load regulation from full load to minimum load

with all other outputs at rated load.

3. Minimum current required on 5V out only.

4. Maximum total power from all outputs is 18 Watts

and no output is to exceed its maximum rated

current.
