NOTICE
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 weak 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 the anti-interference of this power supply.
3. Once use the power supply to charged 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 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.

OPERATION

1. POWER ON
   Press the POWER to switch on power supply and display shows both voltage and current values were set when the device powered off last time.

2. VOLTAGE SETTING
   To rotate the VOLTAGE knob to set the voltage, and the setting “bit” is popped up, turn the knob clockwise to increase values, and turn the knob anticlockwise to decrease values. Press the encoder to shift to the right position, in 3 seconds after voltage setting, the LED lighting exited and the setting is saved.

3. CURRENT SETTING
   To rotate the CURRENT knob to set the current, and the setting “bit” is popped up, turn the knob clockwise to increase values, and turn the knob anticlockwise to decrease values. Press the encoder to shift to the right position, in 3 seconds after current setting, the LED lighting exited and the setting is saved.

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.

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

Attention
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 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.

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.

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.
