How to read this manual
Introduction
Thank you for purchasing the PWR regulated DC power supply
series.
This manual is intended for first-time users of the PWR. It gives an
overview of the regulated DC power supply and describes various
settings, operation, maintenance, safety precautions, etc.
Read this manual thoroughly to use the functions of the PWR
effectively. You can also review this manual when you are confused
about an operation or when a problem occurs.
How to read this manual
This manual is designed to be read from beginning to end. We
recommend that you read the manual thoroughly from the beginning
before using the PWR for the first time.
Related manuals(Remote Control)
For details on the Power Supply Controller, see the operation manual
of the respective product. For connection to a Power Supply Control-
ler and device messaages, refer to the “Connecting & Programming
Guide” [index.html] in the CD-ROM that came with the PIA4800
series.
Intended readers of this manual
This manual is intended for users of the PWR regulated DC power
supply series or persons teaching other users on how to operate them.
The manual assumes that the reader has knowledge about electrical
aspects of regulated DC power supplies.
Information on device messages is provided with the premise that the
reader has sufficient knowledge about controlling power supplies
using a personal computer.

General Description
1.2 Product Overview
The PWR Series are constant voltage/currentautomatic cross-
over power supplies that are capable of delivering voltages and
currents in a wide operating range within the rated output
power.
Communication functions come standard with the PWR which
enable remote control.
Features
●Power-factor improvement circuit
The power-factor improvement circuit reduces the effects of
harmonic currents on the power line.
●High efficiency
The high power conversion efficiency reduces the cost of
power and the cost of heat radiation design during system
configuration.
Communication functions
Equipped with a digital remote control function through TP-
BUS (Twist Pair-BUS) communication. (The total length of
TP-BUS is 200 m.)
By combining with Kikusui’s PIA4800 Series Power Supply
Controller, systemization for applications such as an auto-
matic tester is possible.
Master-slave operation
Output voltage or output current can be expanded by con-
necting multiple power supplies of the same model in series
(only on the L type) or in parallel. This feature allows slave
units to be controlled from a single master unit.
