BENCH TOP
Single Output DC Regulated Power Supply
(Linear mode)
This series of low ripple and noise, adjustable
voltage power supplies are designed for
telecommunication field, workshop, production
line and college. The special designed trifler
wound transformer with thermal fuse and the
extensive overload protection by dissipation
limiting circuitry for the pass transistors make
this series proven and well known for its
reliability and stability.
