FOR UNITED KINGDOM ONLY
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with
the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live (Phase)
As the colours of the wires in main leads may not correspond with the
colours marking identified in your plug/appliance, proceed asfollows:
The wire which is coloured Green & Yellow must be connected to the
Earth terminal marked with the letter E or by the earth symbol
or coloured Green or Green & Yellow.
The wire which is coloured Blue must be connectedto the terminal
which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or
contact the supplier.

This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, cable of
0.75mm2should be protected by a 3A or 5A fuse. Larger conductors
would normally require 13A types, depending on the connection
method used.
Any moulded mains connector that requires removal /replacement
must be destroyed by removal of any fuse & fuse carrier and disposed
of immediately, as a plug with bared wires is hazardous if a engaged
in live socket. Any re-wiring must be carried out in accordance with
the information detailed on this label.

1. PRODUCT INTRODUCTION
1-1. Description
PSH-series Programmable Power Supply is controlled by Micro
Processor Unit (MPU) that can easily connect communication interface
RS-232 or GPIB to computer in order to satisfy user’s demands for
auto-testing and auto-control. The series of products have improved
greatly the shortage of the traditional big size, heavy weight products.
The voltage and current are completely controlled by 12 bits D/A
Converter with higher resolution and accuracy. Also, the digitalization of
system makes a speedy, precise and convenient input of information
controlled by the keyboard and rotation knobs.
The adjustment of voltage/current is made by software calibration
without manual error that will increase the preciseness of the instrument.
The function of Over Voltage Protection (OVP) and Over Current
Protection (OCP) is set with software and detected with hardware to
achieve protected function precisely and speedily in order to prevent
users from danger by using the instrument.
1-2. Features
1) Wide Input Voltage Range and High Power Factor (P.F).
2) High Efficient.
3) Constant Voltage and Constant Current Operation.
4) The protection for Over Voltage, Over Current and Over Heat.

1) Strip the outside insulation on the AC cable approximately 4"(10cm).
Trim the wires to make the ground wire is 0.5"(12mm) longer than
the other wires and join the toric terminals to each stripped wires
individually.
2) Unscrew the base of the strain relief from the helix-shaped body.
Insert the base through the outside opening in the AC input cover
and screw the locknut securely onto the base from the inside.
3) Insert the AC cable through the strain relief base until the outer cable
jacket is adjoined with the edge of the base. Tighten the body to the
base while holding the cable in place and the cable is fastened
securely inside the strain relief.
4) Connect the toric terminals to AC terminals of rear panel
individually.

5. OPERATION METHOD
The voltage and current unit applied for the instrument is Volt and
Ampere.
5-1. Constant Voltage/Constant Current Crossover Characteristic
The working characteristic of this series is called a constant
voltage/constant current automatic crossover type. This permits
continuous transition from constant current to constant voltage
modes in response to the load change. The intersection of constant
voltage and constant current modes is called the crossover point.
Fig.5-1 shows the relationship between this crossover point and the
load.
For example, if the load is such that the power supply is operating
in the constant voltage mode, a regulated output voltage is provided.
The output voltage remains constant as the load increases, up until
the point where the preset current limit is reached. At that point,
the output current becomes constant and the output voltage drop is
proportioned to further increases in load. The crossover point is
indicated by the front panel LCD display. The crossover point is
reached when the CV indicator transfer to CC indicator.
