Triple Output DC Power Supplies

Models 1651A & 1652

Model 1651A Model 1652

Specifications

The models 1651A & 1652 are Triple Output
DC Power Supplies with two variable 0 to
24 VDC outputs capable of supplying 0 to
500 mA, and one fixed 5 VDC output capable
of supplying up to 4 A. Connect outputs in
series for higher voltage or connect in parallel
for higher current output (switch selectable).
Voltage and current metering is provided by two,
three-digit LED displays (model 1652) or two
analog displays (model 1651A). These units are
fully protected against short circuit, overload,
and reverse polarity.
