Job description:
1. UPS function: When the power supply is powered, the power supply directly supplies power to the load through the boost circuit, while charging the lithium battery. Once the power supply is cut off, the battery path is automatically started supplying power to the load through the boost circuit.
2. Booster circuit: peak power up to 20W, power up to 15W, BOST boost circuit, built-in 12A high current MOS, efficiency up to 96%, module static power consumption 25mA, optional 5V/9V/12V output. (Under normal load condition, it is recommended to use <15W. Output 5V: current 3A output 9V: current 1.6A output 12V: current 1.2A)
3. Lithium battery protection: over-pulse, over-discharge, over-temperature, over-current protection (if the short circuit enters the protection state after misoperation and does not output, connect 5V charging automatically activate the recovery output).
Instructions:
1. USB port and standard 5V+ and 5V- are external power supply ports. You can choose one of them. The output interfaces are marked USP + and UPS -. The back welding battery box is connected with 18650 lithium battery. It can also be connected to other 3.7V lithium batteries.
2. When used as a UPS, it is necessary to install the battery so that the input 5V power supply has sufficient power, and the output is kept on in real time. When the power is cut off, the battery can be started at any time.
3. If UPS wants to save energy consumption, read the output indicator light after all tests are completed, which can reduce the power consumption of more than 10 mA without affecting the normal output of the circuit and save.
4. During operation, it is possible to trigger the board to the protection state without output for various reasons (wrong touch, wrong connection, etc.). You can charge a 5V port to the board after the problem is solved, and the board can be activated and output again after it is powered on again.
5. The 5V charging power supply used by individual users uses an output capacitor with a larger capacitance value. This capacitor can continue to discharge after the power is turned off, making the power supply voltage have a slow decline process, which will cause the board to not switch the battery power supply quickly after the power is turned off. If you have such a situation, you can use a discharge resistor of about 1K on the 5V input.
6. If you want to increase the battery capacity of the UPS module, you can use the method of multi-section parallel connection, and other functions are not affected.
