3.2 Operation Instruction
3.2.1 Front Panel Operation Instruction
Panel button that function:
M1 M2M3 M4: Preset storage parameters selection key;
CH1. CH2: Channel selection key
CH3: The third way output voltage select key,can choose 2.5V、 3.3V 、5V voltage output
TRACK: Series select key
PARA/INDEP: Parallel select key
SER/INDEP: Tracking select key
OUT PUT: Output shut off key, You can cut off output , and need not use the power switch;
LOCK key : Easy lock all keys to the panel and all the works will not be external influence;
VOLTAGE . CURRENT :Voltage/current adjust digital coding switch, effectively avoid the noise of the potentiometer, to make the output more
stable and reliable。
3.2.2 Operation Instruction
This series of power supplies with output parameter storage group 16 functions in use can be divided into normal use, pre-storage to
use both cases, normal use, Refer to the following steps:
CH1/CH2 Independent mode:
(1)Confirm the indicator lighton panel PARA SERIAL TRACK closed
(2) Connects the load to the front panel terminals,CH1+/-,CH2+/-。
(3) Set CH1 output voltage and current。Press CH1switch(CH1 indicator lamp light)Adjust voltage and current knob. Low speed rotating work
in fine tuning mode, the high speed rotating work in the thick mode. Press the knob corresponding digital tube twinkle at this time can be a
corresponding numerical adjustment。

(4)CH2 Repeat the above set。
(5) Start OUTPUT, press the OUTPUT key indicator light and displays CV/CC mode。
CH3Independent mode:
CH3 no series/parallel mode, CH3 output is not subject to the influence of CH1 and CH2 mode
(1) Connects the load to the front panel terminals ,CH3+/-。
(2) Choose the output voltage
Press the CH3 key panel voltage output corresponding indicator lamp light, this time the voltage to be automatic output。

CV→CC When the output current value more than 3 A, CH3 lights flashing, CH3 operation mode from the constant
(2) Connects the load to the front panel terminals,CH1+&CH2-(A group of power)。
(3) Choose CH1 channel adjust voltage current, CH2 channel voltage followed CH1 channel , this time working voltage
is the sum of two channels。
(4) Start OUTPUT, press the OUTPUT key. OUTPUT indicator light lights and shows CV/CC mode。

CH1/CH2 mode in series :
(1) Press TRACE key enter the mode in series,TRACE indicator light lights。
(2) Connects the load to the front panel terminals,CH1+&CH2-(A group of power)。
(3)Press CH1/CH2 to choose channel,Adjust voltage current,This time working voltage is the sum of two channels
(4) Start OUTPUT, press the OUTPUT key. OUTPUT indicator light lights and shows CV/CC mode。

CH1/CH2 mode in parallel :
(1)Press PARA/INDEP key enter mode in parallel,PARA indicator light lights。
(2) Connects the load to the front panel terminals,CH1+/-. CH2+/-(A group of power)。
(3)Choose CH1 channel adjust voltage current, CH2 channel voltage followed CH1 channel , this time working voltage
is the sum of two channels.
(4) Start OUTPUT, press the OUTPUT key. OUTPUT indicator light lights and shows CV/CC mode。

Save/exhaled Settings:
Preinstall storage maximum 16 groupe output data preinstall,with M1 output parameters as an example,
the operation procedure is as follows:
(1) Storage operation : Press CH1/CH2Choose storage channel,Press M1 for a long time ,you could store the
current channel data into M1,
Storage success。
When you hear the voice from the buzzer and see the M1 indicator light lights,
(2) The success of the other group storage preset storage method and the same M1;
Press OUTPUT key,According to predetermined status output。

Turn on or turn off the buzzer:
Press CH3 for a long time, I t will turn on or turn of the buzzer。
Panel button lock:
The use of panel keypad lock is on, press the keyboard key lock (LOCK) 2 second or more, digital display "-Loc", said keyboard panel has
been locked, the keyboard is locked, the Operation panel is displayed when "-Loc" prompt, all keys are not working, unlock long again by
the button, you can return to normal status。
4.ATTENTION
4.1 The power supply features over-current protection with sound, when the output short circuit, the circuit protection will be activated
only when a short circuit when troubleshooting to restore output.
4.2 Maintenance of power supply, the input power must be disconnected by repair professionals
4.3 Machine after use, please be ventilated dry place, not long-term, should unplug the power plug
4.4 Belong to high-power instrument of the power supply, at full capacity, therefore they should pay attention to the use of ventilation
and cooling power, and power radiator shell and a higher temperature, please note that hand-to-avoid
4.5 Three core power cord the protective earthing grounding terminal must be reliable to ensure that the use of safety
11
Page 13
4.6 When the power to place too much time re-use, pre-election power 15 - 20 minutes and be stable before equipment put into use
5.MAINTENANCE
The apparatus should be used under normal working conditions, are not allowed in the sunlight exposure, a strong vibration and
occasions with the use of corrosive gases。
5.1 Fuse replacement
If the fuse burned, the equipment will not be able to work. Fuse will not open normally, unless the failure of circuits. Please check before
replacing fuses may cause burning fuse circuit, and then replace the fuse. Fuse replacement, please use the original specifications in
line with the fuse
5.2 Clening
When cleaning the instrument, use neutral detergent Baptist has a soft cloth and water. Do not spray detergent on the surface of the
apparatus, there is probably because of detergent into the internal chassis damage. Do not use with gasoline, benzene, toluene, xylene,
acetone and other chemical substances or similar solvent. Do not use abrasive cleaning products such as the apparatus
