The 1302B Power Supply is a high
performance triple output DC power supply
for industrial and laboratory use.

The two main outputs are continuously
variable from 0 to 32V and can supply 2A
maximum each. They can be operated in
constant voltage or constant current modes.
Automatic overload protection is achieved
by fast transition from CV to CC mode and
may be set at any point in the voltage or
current range. Separate front panel meters
are provided to monitor output voltage and
load current for the 32V sections. Switch
selection is provided to enable either
voltage or current monitoring for each
section. In addition, a separate 5V output is
provided with variation from 4.5VDC to

5.5VDC maximum & maximum current of
5A foldback current limit.

The output voltage and current limit
settings of the 0-32V outputs can be varied
manually using front panel controls.

All of the outputs are floating – neither the
output positive terminal nor the negative
terminal (nor any point within the regulator
circuitry) is connected to ground.

The power supply is designed to operate in
ambient temperature of up to 40 deg C and
full output may be drawn continuously
provided free air circulation is allowed. The
unit is available either in 110-120VAC @
60Hz or 220-240VAC @ 50Hz.

The Global Specialties Model 1302-B Power
Supply is a fully regulated triple output
power source designed to meet virtually DC
voltage requirements. It is an indispensable
tool for product development, testing,
quality control, servicing, and education.
This power supply is especially useful for
analog and digital circuit design, offering a
fixed/variable 5VDC output which is optimal
for TTL applications.
