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 a 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 antielectromagnetic interference circuit inside the power supply, into the earth. Otherwise, false leakage might occur, and it can damage the loading devices or decrease the capacity of anti-interference of this power supply.
  3. Once use the power supply to charge a rechargeable battery (like lead-acid battery), ensure that the positive and negative poles of the power supply are connected to the positive and negative poles of the battery respectively. If not, it might damage the internal rectifying parts of the power supply or the load devices.
  4. Do not operate this power supply in environments such as flammable, explosive, or corrosive gas.
  5. Do not block the vent and keep the power supply to be operated in a ventilated environment.
  6. Based on the output current value, select the suitable output wire and keep the connection tightly to avoid damages on terminals, load devices, or fire in serious cases. Please keep the contact surface clean and rust-free.
  7. If a malfunction occurred, please consult with your local A/S for assistance, or return the defective unit for repairing. Since there is high voltage inside the device (even when power is off, the high voltage can still remain in the circuit for a certain period), please do not attempt to repair or modify it yourself.
  8. Make sure the rating voltage. There are two types of input voltage: AC220V ±5% or AC 110V ±5%.

NOTICE

Make sure to 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 the encoder, which is convenient to use.
  2. Press the OUTPUT push button to activate or exit output of the power supply. The preset voltage value and current value will be displayed once the output is exited.
  3. Once there is a short circuit in the load device, the OCP (short-circuit protection) will be activated, and the power supply will exit output, with the OCP indicator blinking. Once the load device is without a short circuit and the OUTPUT button is pressed, the output will be restored. This function can protect the load device.
  4. The setting voltage and current, and the actual voltage and current are displayed in 4-digit.
  5. Adopt a low-noise and thermal-controlled cooling fan to guarantee a suitable operating temperature.
  6. CV value and CA value can be stored automatically once the power supply is powered off (or shut down). After powering on again, the previously stored values will be used.

OPERATION

1. POWER ON

Press the POWER button to switch on the power supply. The display shows both voltage and current values as set when the device was last powered off.

2. VOLTAGE SETTING

Rotate the VOLTAGE knob to set the voltage. The setting "bit" pops 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. Within 3 seconds after voltage setting, the LED lighting exits, and the setting is saved.

3. CURRENT SETTING

Rotate the CURRENT knob to set the current. The setting "bit" pops 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. Within 3 seconds after current setting, the LED lighting exits, and the setting is saved.

4. OUTPUT PUSH BUTTON

Press the OUTPUT push button to activate or exit the output of the power supply.

5. OCP SHORT CIRCUIT PROTECTION

Press the "CURRENT" knob for 3 seconds to activate (or exit) OCP mode. Rotate "CURRENT" to the right, and the OCP indicator will be lighted up, and the display shows from 0 to 1. After this, press the "CURRENT" knob for 3 seconds, the setting is saved and returns to the original interface. The OCP mode is activated, and the indicator lights up. Under this situation, if the power supply detects a short circuit or overcurrent in the load device, the power supply will exit output, and the OCP indicator will blink to protect the load device. You can press OUTPUT to exit OCP mode and restore the output status.

Note: To exit OCP mode, once under the OCP mode interface, rotate the "CURRENT" knob to the left. The OCP indicator turns off, and the display shows from 1 to 0. Press the "CURRENT" knob for 3 seconds. The setting is saved and returns to the original interface. The OCP mode is exited, and the indicator lights off.

6. OPN SETTING

Press the "OUTPUT" button for 3 seconds to activate (or exit) OPN mode. Slightly press the "OUTPUT" button, and the display shows from 0 to 1. After that, press the "OUTPUT" button for 3 seconds, and the system returns to the original interface. The OPN mode is activated, and the indicator is lighted up.

NOTE: To exit OPN mode, once under the OPN mode interface, slightly press the "OUTPUT" button, and the display shows from 1 to 0, and the OPN indicator lights off. After that, press the "OUTPUT" button for 3 seconds, the system returns to the original interface, and the OPN mode is exited.

7. DISPLAY CONTRAST ADJUSTMENT

Once the display shows "OFF", rotate both "VOLTAGE" and "CURRENT" simultaneously to activate display contrast adjustment. Turning left decreases the brightness, and turning right increases 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 A.
  4. Connect the output terminals of the power supply with the loading device firmly.
  5. Slightly press "OUTPUT" push button, and the "ON" indicator lights up, and the power supply activates the output working.
  6. By pressing the "CURRENT" knob to activate OCP or OPN mode at the desired time.

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 the 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.

⚠ Attention

For effective safety protection, it is only necessary to replace 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.
