Sell XL4015 5A DC to DC CC CV Lithium Battery Step Down Charging Board Led Power Converter Lithium Charger Buck Module best price

5A constant current constant voltage LED driver Li-ion battery charging power module When using this product, please do not put the input ground and output ground of the module together, as this will cause the board high-power current sampling resistor to be bypassed, which will make the module unable to adjust the output current and easily burned when connected to the load. The power chip on the module. This module is easy to use and powerful! Highlights: 1. High power, high efficiency, 5A, low ripple; 2. Three in one: (1) Used as a common step-down module with overcurrent protection capability; (2) It is used as a charger for lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery packs) of various voltage values, and is used in solar panels, wind turbines, etc.; (3) Used as a high-power LED constant current drive module; 3. It has two modes of constant voltage and constant current, and the indicator light indicates which mode the module is currently in; 4. When used as a lithium battery charger, you can set the float charging voltage and charging current size, there is an indicator to indicate whether it is charging or has been fully charged; 5. With current limiting protection function, the module will not be burned even if the output is short circuited. Parameters Input voltage: 4-38V Output voltage: 1.25-36V continuously adjustable Output current: adjustable, 5A Output power: 75W Working temperature: -40~+85 degrees Working frequency: 180KHz Conversion efficiency: 96% Short circuit protection: yes (limit current 8A) Over-temperature protection: Yes (automatically turn off the output after over-temperature) Input reverse connection protection: none, (if necessary, please connect a high current diode to the input) Installation method: 4 pieces of 3mm screw Wiring method: terminal or welding terminal, V-IN is input, V-OUT is output Size: L 51.2mm W 26.2mm H 15mm Application: 1. Used as a common buck module with overcurrent protection capability Instructions: (1) Adjust the constant voltage potentiometer to make the output voltage reach the voltage value you want (2) Use the multimeter 10A current range to measure the output short-circuit current (just 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 current can only reach 4A when you use the module, and the red constant voltage and constant current indicator lights when the current reaches 4A, otherwise the indicator is off) note: When used in this state, since the output end has a current sampling resistance of 0.05 ohms, there will be a voltage drop of 0~0.3V after connecting the load, which is normal! This voltage drop is not pulled down by your load, but dropped to the sampling resistor. other details can feel free to contact us, Thanks ^^
