too hot.
Warning：To avoid any fire or electric shock, please ensure the AC input voltage
fluctuation not exceed 10% of the working voltage range.
Note
：
In some situation, use the mis-configured main voltage for the instrument may
cause the main fuse blew.
Note：If the power supply is used to charge a battery, please pay attention to the
positive and negative polarity to avoid any damage.
After power up, the instrument will automatically perform a self test routine. If the power
supply doesn’t work, then refer to section 1.2.5.

2.2.4 Output verification
The following procedure verify that the power supply outputs the correct voltage and current
levels and properly
responds to entries from the front panel.
Voltage Output Check
The following steps verify basic voltage function without load.
1) Press Power key to turn on the power supply
2) Press On/Off key to enable the output
3) Set the voltage value
Adjust the voltage, then press
to lit the key (indicates it is in the METER mode),
make sure that the set value and output value are same, and if the current displayed on
the VFD is nearly 0A.
4
）Make sure the voltage can be adjusted from zero to the maximum rated value.
5
）
Check the other two channels by the same method.
USER MANUAL

Note: when
Meter key is gray, the power supply is in SET mode, then the VFD
displays the set voltage and current; when the key is lit, then the power supply is
in METER mode, the actual voltage and current display on the VFD. When the
output is OFF, the “OFF” indicater will display at the current display area.

Current output Check
The following steps check the basic current functionality by shorting the power supply’s
output.
1) Press Power key to turn on the power supply
2) Press On/Off
to disable the output, ensure the output is OFF.
3) Connect a short across (+) and (-) output terminals with an insulated test lead, use a
wire sufficient to handle the maximum current.
4) Adjust the voltage value to 1V
5) Press
On/Off to enable the output
6) Adjust t
he current
Set some different current values, in METER mode, check whether the voltage value on
VFD is near 0v, and the current on it is close to the value you set.
7) Make sure that the current can be adjusted from 0 to full rated value.
8) Disable the output and then remove the short wire
9) Check the other two channels by the same method.
2.2.5 If the power supply does not turn on
Use the following steps to help resolve the problems you might encounter when turn
on the instrument:
1) Verify that there is AC power applied to the power supply
First, verify that the power cord is firmly plugged into the power receptacle on the rear
panel of the power supply. You should also make sure that the power source you
plugged the power supply into is energized. Then, verify that the power supply is turned
on.
2) Verify the power-line voltage setting
Make sure the voltage selector switch is set according to the present line voltage
(110VAC or 220VAC) when the power supply is shipped from the factory. Change the
voltage setting if it’s not correct.
3) Verify the correct power
-line fuse is installed
If the fuse was damaged, please see the table below to replace the fuse for your power
supply.

2.2.6 How to exchange the fuse
Open the small plastic cover below the power supply input socket on the back panel with a
screwdriver, and you can see the fuse in it, please use the specifications in line fuse.
Remove the power cord and then use a screwdriver to remove the fuse box.
Use the same specification of fuse to replace the old one, install it to the fuse box and then
insert.
2.2.7 Adjust the carrying handle
To adjust the position, grasp the handle by the sides and pull outward. Then rotate the
handle to the desired position.

Chapter 4 Front-panel Operation
So far we have covered the quick start chapter which briefly introduced the front panel
operation and how to check basic voltage and current functionalit
y. This chapter describes
in detail how to operate the instrument manually via the front-panel keys.
4.1 Front-panel Operation Overview

The power supply is shipped from the factory ready for front-panel operation mode. At
power-on, the power supply will automatically enter the front-panel operation mode and
the instrument can be controlled via the front panel keys and knob.
 The VFD also displays operation states or error information. “
”means the power
button will be lit.
supply is in remote mode.When front-panel keys are locked,
“

 The power supply is in Set mode when it is powered on. In this mode, the VFD will
display the setting voltage and current.
 The output of power supply can be enabled/disabled from the front panel by
pressing the On/Off button.When turn on the output,the VFD will display the state
and voltage/current of each channel.”CC” represents constant current mode.”CV”
represents constant voltage mode.
When output is in OFF mode,VFD will have
no any indicators of CC or CV.
