Data Sheet

Models 1651A & 1652

Triple Output DC Power Supplies

Model 1651A & 1652

The models 1651A & 1652 are Triple Output DC Power Supplies have two 0 to 24VDC outputs capable of
supplying 0 to 500mA, and one fixed 5VDC output capable of supplying up to 4A. 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) & analog displays(model1651A). These
units are fully short circuit, overload, and reverse polarity protected.

Features

• Two 0 to 24VDC, 0 to 500mA outputs

• One fixed 5VDC, 4A output

• Independent or tracking operation

• Adjustable current limiting

• Designed to operate continuously at rated output

• Short circuit, over voltage, and reverse polarity protection.
