High Current Switch
Mode Power Supplies
High current supplies are fully adjustable to 15VDC,
making them suitable for communications racks, HAM
radio stations, autosound display and servicing. Efficient
switch mode design provides high current, with minimal
heat, in a compact lightweight package. Whisper quiet fan
cooling ensures reliable, long-term operation. Dual digital
display simultaneously shows output voltage and current.
Front panel binding posts accepts banana plugs or spade
terminals, providing convenient access. #72-7655 features
banana jacks on the front panel for loads up to 5A, and
heavy-duty stud posts on the rear panel handle loads to
60A. Features: •Bright LED display •Large

Isolated Variable
AC Power Supplies
Variable AC supplies combine the safety benefits of
an isolation transformer with the service advantages
of a variable autotransformer. •Provides isolation from the
AC line when servicing “hot” chassis equipment •Protects
AC powered test equipment •Variable 0~145VAC output
•Safely troubleshoot power supplies, regulators and output
circuits •Minimize damage to associated components
•Dual analog meters simultaneously display output
voltage and current •Independent line input and variable
output fuses provide protection to the variable supply and
the equipment under test •Output fuse may be changed to
a lower value, allowing service tech to set current limit
•Grounded 6' line cord and outlets

Switch Mode Laboratory DC Power Supplies
Precision adjustable supplies are ideal for test, measurement and service
applications where tight voltage and current regulation are critical. Highly
efficient switch mode design delivers outstanding performance from an
extremely compact footprint. Unique separate output ON/OFF control allows voltage and current setting, with the supply
output turned off. Features: •Backlit four digit LCD display •Simultaneous display of voltage and current •Auto selecting
constant voltage (CV) and constant current (CC) modes •Ultra quiet convection cooling •Short circuit, overload, over
voltage and thermal protection •84% efficiency at maximum output •RoHs compliant
