ITEM NAME:1 Pc 5A Constant Current Constant Voltage LED Driver Battery Charging Module New Descriptio n Description: ★ This module is an adjustable step-down module that can be used to change the output voltage by adjusting the blue adjustable resistor on the module. The input and output voltage difference is 1V, and the output voltage is 0.8V. ★ The IN- (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) indicated on the module must be connected correctly. Otherwise, the module may be damaged. ★ Battery charging: 1. Determine the float voltage and charge current of the rechargeable battery you need, the input voltage of the module; 2. Adjust the constant voltage positioner and adjust the output voltage to about 5V. 3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value; 4. The charge-to-light current defaults to 0.1 times the charge current (constant current value). 5. Adjust the constant voltage position device to make the output voltage reach the float voltage; 6. Connect the battery and try to charge. (1, 2, 3, 4, 5 steps are the module input power supply, the output is not connected to the battery.) ★ LED constant current drive: 1. Determine the operating current and high operating voltage that you need to drive the LEDs; 2. Adjust the constant voltage positioner and adjust the output voltage to about 5V. 3. Use the multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current; 4. Adjust the constant voltage position device to make the output voltage reach the high working voltage of the LED; 5. Connect the LED and test the machine. (1, 2, 3, 4 steps are connected to the power supply of the module, and the output is not connected to the LED light..★ The IN- (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) indicated on the module must be connected correctly. Output Current: Adjustable. 5A Maximum. ★ LED constant current drive.
