Method of operation

  1. Power on: Press the POWER button to tum on the power, and the screen will display the voltage and current values that were set when the machine was turned off last time.
  2. Voltage setting: Regardless of whether the power supply is in the output slate, you can Wm the “VOLTAGE” coding switch to set the voltage. When It enters the voltage setting state, The currently set “bit” is prompted by flashing; tum clockwise to increase the value, and tum counterclockwise to decrease the value. Presa the coding switch to shift to the left. 5 seconds after the voltage setting operation Is completed, the flashing stops, and the current setting value is stored.
  3. Currant setting: Regardless of whether the power supply Is In the output state, you can rum the “CURRENT” coding switch to set the current. When entering the current setting slate, the currently set “bit will flash in a flashing way, tum clockw1se to Increase the value, and tum counterclockwise to decrease the value . Press the coding switch to shift to the left 5 seconds after the current setting operation is completed, the flashing stops, and the cul1’8nt setting value is stored.
  4. Output switch: Short press the “Output” button on the panel, you can switch the power output and turn off’.
  5. OCP short circuit protection: WPS model: Presa the “Current coding switch for 3 seconds to tum on (or tum off) the OCP short-circuit protection alarm function. APS model: Press the “OCP” button to tum on (or tum off) the OCP short-circuit protection alarm function. After the OCP protection alarm function is turned on, when the machine detects a short circuit or over current in the external load, the machine will stop output and give an alarm to effectively protect the external load. In the OCP short-circuit alarm state, short press the Output key to release the alarm state and enter the closed output state.

Examples of use:Set the power supply 10 12V and the current to 3A The operation Is as follows:

  1. Turn on the power switch,
  2. Rotate the “VOLTAGE” coding switch to preset the voltage 1o “12.00”V.
  3. Rotate the “CURRENT” coding switch to preset the current to “3.000”A.
  4. Connect the output terminals on the panel of the machine to the load equipment correctly and firmly with appropriate wires.
  5. Short press the “Output’ output button, the Indicator light will light up, and the machine will output normally.
  6. If you need to enable the short-circuit protection (over-current protection} function, you can press the -OCP” button at any time (WPS model, long press the “CURRENT” coding switch) to enable this function.

Note:

  1. In the 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 continues to decrease, the current will remain at the current setting Value, the voltage drops proportionally {l=V/RJ. At this lime, increase the load resistance or increase the current setting value to restore the CV output state.
  2. The machine Judges whether there Is a short circuit In the output, based on whether the output current is greater than the current set by the user. Therefore, when the OCP short -circuit protection function is enabled, the machine cannot be used in constant current mode.

Connect load equipment

  1. Rotate counterclockwise to loosen the terminal knob
  2. Put the output wire terminals Into the terminal screw according to the positive and negative poles
  3. Tum clockwise to tighten the terminal knob
  4. Firmly connect !he other end of the wire with the positive and negative poles of the load device.

Note: Incorrect connection may cause damage to the power supply and the load connected to the power supply. When connecting a battery load, do not connect the “+” and “-” poles reversely, as this may damage the power supply.

Constant voltage/constant current characteristics:  

The working characteristic of this series of power supplies is constant voltage/constant current automatic conversion type, which can automatically change between constant voltage and constant current states with the change of load. The intersection point between constant voltage and constant current is called the conversion point. For example, If the load makes the power supply work in a constant voltage mode, it outputs a constant voltage. A:s the load increases, the output voltage will remain stable and the output current will increase. When the current value reaches the set current limit value, the pawer supply will automatically switch to constant current mode. The output current remains stable, and the output voltage decreases proportionally with the further increase of the load. The conversion between constant voltage and constant current is indicated by the LED on the front panel. The CV indicator light is on when the voltage is constant, and the CC Indicator light Is on when the current is constant.
