NOTE
This lead/appliance must only
be wired by competent persons
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.

EARTHED
IMPORTANT
The wires in this lead are
coloured in accordance with
the following code:

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.

Description of Circuit Theory
1) +10V Voltage reference circuit：
Start up the circuits of R306 and D302 to ensure the output voltage of OPA U301, PIN 1 is in positive status when power is on.
At this moment, the output voltage of PIN 1 will pass through R307 to maintain the voltage of both ends of ZENER DIODE
ZD301(6.2V) to 6.2V. As OPA has the character of false short circuit, so U301 PIN3=6.2V, refer to the following formula:
Therefore, the OPA’s output voltage can be changed by adjusting the VR301 as shown in the following formula:
Vref=10V→VR301=1.14kΩ
2) Voltage Adjusting Circuit
The R311, and R313 are voltage feedback attenuating resistors while R312 is to control the output of Reference voltage. Please
refer to the following formula:
If Vref=10V R311=52.3kΩR313=20kΩ
And the R316, R317, C313, C314, and C315 are compensated circuits for voltage frequency.
3) Current Adjusting Circuit:
The U302 is an ErrorAmplifier with the gain at:
For example: IPS-1820D, Io=20A，R341=10mΩ

6.OPERATION INSTRUCTIONS
6-1.Precaution
(1)AC input
AC input should be within the range of line voltage±15% 50/60Hz.
WARNING: To avoid electrical shock, the power cord protective grounding conductor must be
connected to ground.
(2)Installation
The machine itself is a heating source , please don't pile up the machine while operation. Keep the machine from other
heating source at least for 10cm to assure a sufficient space for radiation in order to extend the life of the machine. The heat
sink located at rear of the power supply must have sufficient space for radiation.
CAUTION: To avoid damaging the power supply, don’t use it in a place where ambient
temperature exceeds 40℃.
6-2.Setting Current Limit
(1) Determine the maximum safe current for the device to be powered.
(2) Temporarily short the (+) and (-) terminals of the power supply together with a test lead.
(3) Rotate the COARSE VOLTAGE control away from zero sufficiently to have the CC indicator lightened.
(4) Adjust the CURRENT control for the desired current limit. Read the current value on the Ammeter.
(5) The current limit (overload protection) has now been preset. Do not change the CURRENT control setting after this step.
(6) Remove the short between the (+) and (-) terminals and hook up for constant voltage operation.

E13
6-3.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 LED indicators. The crossover point is reached when
the CV indicator goes out and the CC indicator is on.
Fig. 5-1 Constant Voltage/Constant Current Characteristic.

E14
Similarly, crossover from the constant current to the constant voltage mode automatically occurs from a decrease in
load, a good example of this would be seen when charging a 12 volt battery. Initially, the open circuit voltage of the
power supply may be preset for 13.8 volts. A low battery will place a heavy load on the supply and it will operate in
the constant current mode, which may be adjusted for a 1 amp charging rate. As the battery becomes charged, and its
voltage approaches 13.8 volts, its load decreases to the point where it no longer demands the full 1 amp charging rate.
This is the crossover point where the power supply goes into the constant voltage mode.
6-4.Operation mode: Voltage Operation Mode:
A. Set Power switch to “OFF” position.
B. Make sure that line voltage is correct for the input power voltage.
C. Plug power cord into the power outlet.
D. Set Power switch to “ON” position.
E. Adjust “Voltage” and “Current” control to the desired output voltage and current.
F. Connect the external load to the output binding posts. Make sure both “+” and “-” terminals are connected correctly.

E15
7. MAINTENANCE
The following instructions are used by qualified personnel only. To avoid electrical shock, do not perform any
servicing other than the operating instructions of the manual unless you are qualified to do so.
7-1.Fuse Replacement
If the fuse blown, the CV or CC indicators will not light and the power supply will not operate. The fuse should not
normally blow unless a problem has developed in the unit. Try to determine and correct cause of the blown fuse, then
replace only with a fuse of the correct rating and type.
The fuse is located on the rear panel (see Fig. 4-2).
WARNING: For continued fire protection. Replace with 250V fuse of the specified type and rating,
and disconnect the power cord before replacing fuse.
7-2.Line Voltage conversion
The primary winding of the power transformer is tapped to permit operation from 115/230 VAC, 50/60 Hz line voltage.
Conversion from one line voltage to another is done by change AC selects switch as shown in Fig. 4-2.
To convert to different line voltage, perform the following procedure:
(1) Make sure the power cord is unplugged.
(2) Set the AC switch to the desired line voltage position.
(3) The change of line voltage may also require a corresponding change of fuse value. Install correct fuse value
according to the instruction shown on rear panel.
WARNING
