How to Use:
- Use method as an ordinary buck module with over current protection capability:
B. Adjust the digital meter to the display output current interface, and directly short circuit the output terminal of the module (just find a thick wire to short circuit the output terminal), at this time adjust the "constant current potentiometer" to make the current value reaches the preset overcurrent protection value; (for example, the current value displayed by the on board ammeter is 4A, then the maximum current of the module is limited to 4A, and the red indicator light is on when the current reaches 4A)
C. Connect the load and work.
- Use as a battery charger:
C. Adjust the digital meter to the display output current interface, and directly short circuit the output terminal of the module (just find a thick wire to short circuit the output terminal), at this time adjust the "constant current potentiometer" to make the The current value reaches the preset charging current value;
e. Connect the battery and charge it.
(In step 1, 2, 3, 4, the input terminal is connected to the power supply, and the output terminal is not connected to the battery without load).
- Use as LED constant current drive module:
C. Adjust the digital meter to the display output current interface, and directly short circuit the output terminal of the module (just find a thick wire to short circuit the output terminal), at this time adjust the "constant current potentiometer" to make the The current value reaches the preset LED working current;
D. Connect the LED and test the machine.
(In step 1, 2, and 3, the input is connected to the power supply, and the output is no load without the LED light)
Features:
1Practical Use: Can also work as voltmeter, ammeter and power meter, an excellent replacement for multimeter with clear view and easy operation. 2USB Interface: The on board USB interface can easily charge your digital products. And the USB output voltage is the same as the module output voltage, not a fixed 5V output, please confirm before charging the USB device. 3Functionality: Can be used as an ordinary buck module with over current protection, a charger for various batteries, and a high power LED constant current drive module. 42 Work Modes: There are 2 modes, constant voltage and constant current, and an indicator light indicates which mode the module is currently in. 5Easy Setting: When used as a lithium battery charger, you can set the float voltage and charging current, and there is an indicator light to indicate whether it is charging or fully charged. 6Safe Working: With current limiting protection function, the module will not be burnt out even if the output is short circuited. 7High Accuracy: The on board voltmeter and ammeter can be self calibrated, and there will never be inaccurate problems.
