โมดูล 2 in 1 5 A DC-DC Adjustable Power Step-Down Buck CC / CV Charge Board https://shopee.co.th/Bel-%E0%B9%82%E0... 2 in 1 5A DC-DC Adjustable Power Supply Step-down Buck Charge Module CC/CV Lithium Charge Board LED Driver Voltmeter Ammeter Constant Current Constant Voltage Feature: 1. On-board voltage, current, power meter, no multimeter can also easily use this module, easier and more intuitive. 2. Built-in USB interface, can easily charge your digital products. (Note: USB and module output voltage are consistent, 5V output is not fixed, make sure it before charging USB device) 3. High power, high efficiency, 5A, low ripple; 4. Function: (1) As a general step-down module with overcurrent protection; (2) Various lithium voltage batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery pack) charger used for solar panels, wind turbines and other cases; (3) Used as a high-power LED constant-current driving module. 5. With a constant voltage and current 2 modes, there are indicators that the module is currently in what mode; 6. When used as a lithium charger, you can set the voltage of the float and the size of the charge current, an indicator light indicating whether it is charging or full. 7. With current limiting function, even if the output short circuit will not burn the module. 8. On-board voltage, ammeter can be self-calibrating, will never be inaccurate! 9. With heat sink, copper holders are presented! Specification: Input voltage: 5-36V Output voltage: 1.25-32V continuously adjustable Output current: adjustable, maximum 5A (recommended for use within 4.5A) Output power: 75W Maximum (50W recommended, please reduce power if there is large pressure difference) Operating temperature: -40 ~ + 85 ℃ Operating frequency: 180kHz Conversion efficiency: up to 96% Short circuit protection: Yes Overheat protection: Yes (if overheating, automatically turns off the output) Input reverse protection: no, (if required, enter a rope in a high current diode) Installation: 4pcs 3mm screws Wiring method: terminal or welding terminal, V-IN for input, V-OUT for output Module size: 68.2x38.8x15mm/2.69x1.53x0.59'' Weight: 39g Application: 1. Used as a normal step-down module with overcurrent protection Instructions (1) Right-click, adjust the digital counter to display the output voltage interface, adjust the "DC voltage potentiometer", so that the output voltage is at the desired voltage value; (2) Adjust the digital table to the (output current of the display) interface, directly the short output of the module (to find the thick short-circuit wire can be), then adjust the value of the "DC voltage potentiometer" current reaches the preset overcurrent protection value; (For example, the current value displayed on the on-board ammeter is 4A, then the maximum current of the module is limited to 4A, the current to 4A when the red indicator light) (3) Connected to the load, running. 2. Used as a charger The non-constant current function of the module cannot be used to charge the battery, due to the
