The module uses the domestic high-quality LM2596 chip, which has high efficiency (92%), and at the same time, the heat generation is small, and it can easily reach a current of more than 3A. At the same time, it cooperates with the original TI op amp to control the output current, so that the overall output is very stable.2. This module uses the original Sanyo filter capacitor with low ESR, which can make the ripple voltage as low as 50mV 3. This module is an adjustable step-down module, and the output voltage can be changed by adjusting the blue adjustable resistor on the module. The input and output voltage difference is 2V, and the small output voltage can be 1.23V.4. 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 How to use:1. Determine the float voltage and charging current of the battery you need to charge, and the input voltage of the module;2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.3. Use the 10A current block of the multimeter 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 default current of the charging switch lamp is 0.1 times the charging current (constant current value), if you need to adjust it, please adjust the switch lamp current potentiometer; (generally do not need to be adjusted)5. Adjust the constant voltage potentiometer to make the output voltage reach the floating voltage;6. Connect the battery and try charging.(Steps 1, 2, 3, 4, and 5 are for the module input to connect to the power supply, and the output no-load to not connect to the battery.)LED constant current driver Usage:1. Determine the working current and working voltage you need to drive the LED;2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.3. Use the 10A current block of the multimeter to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED working current;4. Adjust the constant voltage potentiometer to make the output voltage reach the LED working voltage;5. Connect the LED and test the machine.(Steps 1, 2, 3, and 4 connect the power supply to the module input, and do not connect the LED light to the output without load.)Package Included1 Pcs 5V 600MA Boost Module
