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 as follows:
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 connected to 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 0.75mm ²should 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. INTRODUCTION
This series of switched mode power supplies have removed the inconvenience of big volumes and heavyweight
associated with traditional power supplies.
The output voltage and current are controlled by two variable resistors with coarse and fine regulation for simple and
precise adjustment.
Features:
lWide input voltage range— 97V~133V (for 115V) and 195V~265V (for 230V).
lWith high frequency operation the size of power the transformer is reduced
lWith small size, light weight and high power density.
lEntire efficiency rate up to 70%.
lConstant current and constant voltage modes.
lZero adjustment for the voltage and current output.

3. PRECAUTIONS BEFORE OPERATION
3.1 Unpacking the Switched ModePower Supply
The instrument has been fully inspected and tested before shipping from the factory. Upon receiving the instrument,
please unpack and inspect it to check if there is any damages caused during transportation. If any sign of damage is
found, notify the bearer and/or the dealer immediately.
3.2 Checking the Line Voltage
The instrument can be connected to any of the line voltages shown in the table below. Before connecting the power
plug to an AC line outlet, make sure the voltage selector on the rear panel is set to the correct position corresponding to
the line voltage. The instrument might be damaged if connected to the wrong AC line voltage.
WARNING: To avoid electrical shock the power cord protective grounding conductor must be
connected to ground.
When line voltages are changed, replace the required fuses shown below.
Line voltage Range Fuse Line voltage Range Fuse
115V 97-133V T 10A 250V 230V 195-265V T 6.3A 250V
WARNING: To avoid personal injury, disconnect the power cord before removing the fuse
holder.

3.3 Environment
The normal ambient temperature range of this instrument is from 0°to 40°C (32°to 104°F). Operation of the
instrument above this temperature range may cause damage to the circuits.
Do not use the instrument in a place where strong magnetic or electric fields exist as they may disturb the
measurement.
3.4 Equipment Installation, and Operation
Ensure there is proper ventilation for the vents in the IPS power supplies case. If this equipment is used in a manner
not according to the specification, the protection provided by the equipment may be impaired.
WARNING: This is a Class A product. In a domestic environment this product may cause
radio interference in which case the user may be required to take adequate measures.
