High current 5A constant current and constant voltage LED driver Li-ion battery charging power module 5A constant voltage constant current module When you use this product, please do not share the input ground and output ground of the module together. This will cause the high-power current sampling resistor of the board to be bypassed, so that the module cannot adjust the output current, and it is easy to burn when connected to a load. The power chip on the module. This module is easy to use and powerful! ! ! A module has 3 major functions, which can satisfy most of your occasions! ! ! Module highlights: 1. High power, high efficiency, 5A, low ripple; 2. Three in one: (1) Use as an ordinary step-down module with over-current protection capability; (2) Used as a charger for various voltage values ​​of lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery packs), used in solar panels, wind generators and other occasions; (3) Use as a high-power LED constant current drive module; 3. It has two modes of constant voltage and constant current, and there is an indicator light to indicate which mode the module is currently in; 4. When used as a lithium battery charger, you can set the float voltage and charging current, and there is an indicator light to indicate Shows whether it is charging or fully charged; 5. With current-limiting protection function, the module will not be burnt out even if the output is short-circuited. 1. Module parameters Input voltage: 4-38V Output voltage: 1.25-36V continuously adjustable Output current: adjustable, maximum 5A Output power: max 75W Working temperature: -40~+85 degrees Working frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes (limited current 8A) Over-temperature protection: Yes (automatically shut down the output after over-temperature) Input reverse connection protection: None, (if necessary, please insert a high-current diode in series in the input) Installation method: 4 3mm screws Wiring mode: wiring terminal or welding terminal, V-IN is input, V-OUT is output Module size: length 51.2mm width 26.2mm height 15mm Weight: 23g Second, the scope of application 1. Use as an ordinary step-down module with over-current protection capability Instructions: (1) Adjust the constant voltage potentiometer to make the output voltage reach the voltage value you want (2) Use a multimeter to measure the output short-circuit current with a 10A current file (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer to make the output current reach the predetermined overcurrent protection value. (For example, the current value displayed by the multimeter is 4A, then the maximum current when you use the module can only reach 4A, when the current reaches 4A, the red constant voltage constant current indicator will be on, otherwise the indicator will be off) Note: When used in this state
