Special Features

  • 【Switch Display Parameters】: in the normal interface, press SW to switch the display below the display screen, and switch the display content between current A power W capacity Ah time h. Long press SW button to switch the uplink display on the display screen and switch the display content between input voltage IN output voltage OUT.
  • 【Set Output Voltage】: press U/I button in the normal interface to enter the interface of setting voltage constant current. It can be seen that a certain digit of the output voltage value is flashing. Rotate the encoder left and right to adjust the major and minor. Short press the rotary encoder to choose which bit of output voltage to set. After setting, press U/I button 2 times to return to the normal interface. Or automatically return to the normal interface after stopping operation for 10s.
  • 【Set the Default On/Off State of Module Power】: long press U/I in the normal interface to enter the parameter setting interface.You can see that it shows "OPEN OFF" or "OPEN ON". "OPEN OFF" means the output is turned OFF by default when power is ON, and "OPEN ON" means the output is turned ON by default when power is ON.Long press rotate encoder to switch two states. After setting, long press U/I to return to the normal interface.
  • 【Safe Protection】: the module is with Anti-reverse connection protection of input end, so that it will not burn out when there is reverse connection. Anti-backflow protection at the output end. No need to add anti-backflow diode when charging. Multiple software protection mechanisms are available, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off.
  • 【Note】: in order to ensure the accuracy of calibration, calibration voltage -- above 12V can only be started; Calibration current - start calibration only when the current is above 1A.
