Tenma Model 72-7655
High Current Switch Mode Power Supply with Remote Sensing and Control
User Manual
1.
INTRODUCTION
This 900W switching mode DC regulated dual output power supply series provides high current with
constant current limiting protection
, and va
riable output
of
1
.0
~ 15V
DC.
It is designed with a high
ly
efficient
Active Power Factor Corrector. The remote sensing terminal is
used to compensate for long output line losses.
The output voltage level can be externally controlled via th
e
remote control terminal.
