Regulated DC Power Supply
Introduction of the products
The PAN series is an automatic constant voltage/constant
current shifting regulated DC Power supply
equipped with the
phase control pre-regulator. A series regulator system is
used to assure low-noise and stable output.
The PAN series are featured with the following points.
• The two distinctly visible LED display units on the front
panel display output voltage, output current and various
• The output control potentiometer (for voltage and current
presetting) is of a 10-turns wire-wound design, and allows
• Electronic switch for low chattering and noise is used to
turn on and off the power output.
• Using external voltage or external resistor, output
voltage and current can be remote-controlled. With the GPIB
available with our PIA3200, an automatic testing
system can be formed.
• The phase control pre-regulator is furnished with a choke
input smoothing circuit, which decreases apparent input
power and suppresses harmonic components in the input
current. Therefore, potential effects on the power line,
such as input voltage distortion, are decreased.
• High-speed transient response of 50 j± s allows it to
follow a sudden load change.
• Carefully selected parts, improved circuit, and forced air
cooling heat dissipation combine to produce an excellent low
temperature drift of 100 ppm/°C (constant voltage
• To protect a load from unexpectedly excessive voltage, the
unit includes a built-in OVP (over-voltage protection)
circuit capable of handling voltages 10-110% of the rated
With the above-mentioned features, PAN series units offers a
wide range of applications to laboratory experimental
equipment, test equipment for mass-production lines, power
supply for aging, etc.

outlines the features of each model.
Chapter 1 Setup
Describes the necessary procedure from unpacking to
preparation before use. Since details on installation
location and Power supply
are provided, be sure to read this
chapter before using the unit for the first time.
Chapter 2 Basic Operation
Describes the unit's start-up function, protection circuit,
and the basic operations managed from the front panel of the
Chapter 3 Applied Operation
Explains the remote control of the unit, and use of multiple
number of Power supply
in combination to increase output
Chapter 4 Names and Functions of Controls
Provides an outline of the switches and terminals on the
panels, including their names and functions.
