NOTICE
65
When operating the power supply, please ensure the power
cord is grounded well, if the power socket has no grounding,
you can connect the housing case of power supply with the
wire to ground. Good grounding can prevent power supply
leakage and reduce output ripple interference.
CAUTIONS
1- Please use the power cord which is compliant with the rated
power of this device.
2- Before operating, the device must be grounded in order to
conduct the week leakage current, which caused by the anti-
electromagnetic interference circuit inside the power supply,
into the earth. Otherwise the false leakage might be occurred,
and it can damage the loading deices or decrease the capacity
of anti-interference of this power supply.
3- Once use the power supply to charge the rechargeable battery
(like lead-acid battery), ensure that the positive and negative
poles of the power supply are connected to positive and negative
poles of battery respectively, if not, it might damage the internal
rectifying parts of power supply or the load devices.
4- Do not operate this power supply in the environments such as
flammable, explosive, corrosive gas.
5- Do not block the vent and keep the power supply to be operated
at ventilation environment.
6- Based on the output current value to select the suitable output
wire and keep the connection tightly, to avoid damages on terminals,
load devices, or fire in serious case, please keep contact surface is
clean and rust-free.
7- If malfunction occurred, please consult with your local A/S for
assistance, or return the defective unit for repairing. Since there is
high voltage inside of device (even power off, the high voltage is still
remains in circuit for a certain of period), please do not tempt to repair
or modify by yourself.
8- Make sure the rating voltage, there are two type of input voltage:
AC220V±5% or AC 110V±5%
NOTICE
Make sure input the correct AC voltage, the wrong AC voltage
will damage the device.
FEATURES
1- CV (constant voltage) and CC (constant current) shift mode
automatically, both CV value and CC value can be preset
through encoder, which is convenient to use.
2- Press the OUTPUT push button to activate or exit output of
power supply, and the preset voltage value and current value
will be displayed once exit output.
3- Once there is short circuit in load device, the OCP (short-
circuit protection) will be activated and power supply will exit
output and OCP alarmed twinkly. Once load device is without
short-circuit and press OUTPUT button to restore the output.
This function can protect the load device.
4- The setting voltage and current and actual voltage and
current are displayed in 4-digit.
5- Adopt low noise and thermal controlled cooling fan to
guarantee the suitable operating temperature.
6- CV value and CA value can be stored automatically once
power supply powered off (or shut down), after power on
again, the previous stored values will be used.

4-OUTPUT PUSH BUTTON
To press OUTPUT push button to activate or exit output of
power supply.
5-OCP SHORT CITCUIT PROTECTION
To press “CURRENT” knob for 3 seconds to activate (or exit)
OCP mode, rotate “CURRENT” to right and OCP indicator will
be lighted up and display showed from 0 to 1, after this to press
“CURRENT” knob for 3 seconds, the setting is saved and return
the original interface, the OCP mode is activated and indicator
lights up. Under this situation, if the power supply detect there
is short-circuit or over current occurred in load device, the power
supply will exit output and OCP indicator twinkled to protect the
load device. You can press OUTPUT to exit OCP mode and
restore output status.
Note: In order to exit OCP mode, once under OCP mode interface
and rotate “CURRENT” knob to left, the OCP indicator turns off
and display from 1 to 0, press “CURRENT” knob for 3 seconds,
the setting is saved and return the original interface, the OCP
mode is exited and indicator lights off.
6-OPN SETTING
Press “OUTPUT” button for 3 seconds to activate (or exit) OPN
mode, and slight press “OUTPUT” button and the display shows
from 0 to 1. After that, press “OUTPUT” button for 3 seconds and
system returns original interface, the OPN mode is activated and
indicator is lighted up.
NOTE: In order to exit OPN mode, once under OPN mode interface,
slightly press “OUTPUT” button and display shows from 1 to 0 and
OPN indicator lights off, after that, press “OUTPUT” button for 3
seconds, the system returns original interface and OPN model is
exited.
7-DISPLAY CONTRAST ADJUSTMENT
Once display shows “OFF”, rotate both “VOLTAGE” and “CURRENT”
simultaneously to activate display contrast adjustment, turning left
to decrease the brightness and turning right to increase brightness.
EXAMPLE
To set the power supply as voltage as 12V and current as 3A.
Operating is as follows:
1-Switch on the power supply
2-Rotate “VOLTAGE” knob to preset the voltage value as 12.00 V.
3-Rotate “CURRENT” knob to preset the current value as 3.000 V.
4-Connect the output terminals of power supply with the loading
device firmly.
5-Slightly press “OUTPUT” push button and “ON” indicator lights
up and power supply activate the output working
6-By press “CURRENT” knob to activate OCP or OPN mode at
desired time.

FUSE REPLACEMENT
If the fuse blows, the power supply will stop working.To find and
correct the cause of the blown fuse, then replace it with a fuse of
the same specification.
Fuse cabin is in the power socket
Replace the fuse of same
specification,then put the fuse
cabin back.
HIGH VOLTAGE!
DANGER!
For effective safety protection, it is only necessary to
4replace the fuse of a specific specification. Before
replacing the fuse,the power must be turned off and the
power cord must be unplugged from the power outlet.
automatically switch to constant current mode. The output
current remains stable and the output voltage decreases
proportionally as the load increases further.The conversion of
constant voltage and constant current is indicated by the LED on
the front panel.
CV indicator light is on during constant voltage, CC indicator is
on when constant current.
109
Remove the power plug first,then open
the fuse cabin according to the
illustration.
!
Attention
In actual CV operation, if the load resistance decreases and the
output current increases to the set current value, the power supply
will automatically switch to CC mode.When the load resistance
value continues to decrease, the current will remain at the current
set value.The voltage is proportionally reduced. At this time,
increase the load resistance or increase the current set value to
restore the CV output state.
CONNECT THE LOAD
1. Rotate the terminal knob by turning it counterclockwise
2. Insert the load terminal
3.Turn the terminal knob clockwise
4. Banana plug can be directly inserted into the terminal hole
Improper connection may result in damage to the power
supply and the load connected to the power supply.When
connecting the battery load, do not reverse the polarity of
the “+” and “-" as this may damage the power supply.
CONSTANT VOLTAGE/CONSTANT CURRENT
CHARACTERISTICS
The working characteristics of this series of power supplies are
constant voltage/constant current automatic conversion type,
which can automatically change between constant voltage and
constant current states with load changes. The intersection
between constant voltage and constant current mode is called
conversion point.For example, if the load causes the power
supply to operate in a constant voltage mode, a constant voltage
is output. As the load increases, the output voltage will remain
constant and the output current will increase.When the current
value reaches the set current limit value, the power supply will
