Product Introduction
The LX-2BUPS module is actually a charger and UPS that is suitable for using flat-top 18650 size lithium batteries.
This module can also be used as a UPS with a 12V, maximum 3A output.
The LX-2BUPS module has a 5V, 1A input that you can use in addition to the USB Type-C input from the existing soldering pads.
This product is suitable for the application of power failure equipment without power failure, use external power supply when there is power, and automatically and seamlessly switch Battery powered.
If you use the USB interface for power supply, you recommend use the Type-c interface.
Compared with the microUSB interface, you can use the power
Suitable for
routers, cameras, development boards and other equipment, power-off seamless switching battery power supply, power-off without network
External power supply and battery dual supply seamless switching (no delay).
Uninterruptible power supply, self-starting when power failure, self-charging when incoming calls.
Lithium battery charging, lithium battery protection, boost output, UPS switch four practical functions,
The two-color LED indicates the charging status, and the full green light is always on, and the charging will automatically stop.
Type-C interface, through the current is large.
Function Description
1. UPS function:
when the power supply has electricity, the power supply directly supplies power to the load through the boost circuit and charges the lithium battery at the same time.
Electricity but the power is lost, the auto-start battery path supplies power to the load via the boost circuit.
2. Boost circuit:
peak power up to 20W, rated power up to 15W.
5V: Current 3A
3. Lithium battery protection:
overshoot, overdischarge, overtemperature and overcurrent protection (if it enters the protection state after misoperation and short circuit, it will not lose
Out, access 5V charging automatically activates the recovery output).
1. USB port and standard 5V and 5V-are external power supply ports, and one of the two can be selected.
The output interfaces are marked with UPS.
The back welding battery box is connected to the 18650 lithium battery.
Can also be connected to other 3.7V lithium batteries.
2. When used as UPS, the battery shall be installed to ensure that the input 5V power supply has sufficient power, the output shall be turned on in real time, and the battery power supply can be started at any time when the power supply is cut off.
3. If UPS wants to save energy consumption, weld down the output indicator after all tests are completed, which can reduce the current consumption of more than 10 mA without affecting the normal output of the circuit and save electricity.
4. During the use and operation, it is possible to trigger the board to enter the protection state and not output due to various reasons (false touch, wrong connection, etc.). After eliminating the problem, the board charging port can be connected to 5V charging, and the board can be activated and re-output after re-energization.
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 supply is cut off, so that the power supply voltage has a slow drop process, which will cause the board to not switch battery power supply quickly after the power supply is turned off. If you encounter such a situation, you can connect a discharge resistor of about 1K in parallel with the 5V input port.
6. If you want to increase the battery capacity of UPS module, you can use multiple parallel connections, and other functions will not be affected.
