REGULATED DC POWER SUPPLIES
80
The PR-A Series of series-regulated CV/CC power
supplied were designed to provide a compact power
supply package with high performance, and ensure
excellent reliability as well as excellent design. Seven
types are available for a variety of requirements, three
18 V types, two 36 V types, one 70 V type and one 250
V type. Whether used individually or connected in
series or parallel for greater capacity, the PR-A Series
ensures excellent performance. These power supplies
are housed in a compact rack-mount package and can
be used on the bench top as well.

Low Ripple, Low Noise
Series regulation achieves extremely low ripple and noise, as well
as a very low temperature coefficient and excellent electrical
characteristics.
Series Operation, Parallel Operation
Several power supplies can be connected in series to boost output
voltage capability, or in parallel to boost output current capability.
In addition, with the parallel connection method, master-slave
setup lets you control the output from just one of the connected
supplies.
OUTPUT ON/OFF Switching
The output can be switched on and off with a switch on the front
panel.
CV/CC LED indicators
The green LED lights during CV operation and the red LED lights
during CC operation.
Floating Output Method
Because the output terminals are floating, operation is possible as
either a positive or negative power supply.
PR-A Series Parallel-Connected Operation
It is possible to connect several of the same model of PR-A Series
power supplies in parallel to increase current capability. Output is
controlled from one master unit.
