Features: 1. Equipped with UPS circuit, it can achieve seamless switching between power and battery dual power supply without delay 2. It can be powered by a single battery, and the battery can be unplugged and replaced at any time 3. Suitable for low-power DC equipment instruments and other uninterruptible power supply solutions, with self starting during power outages and self charging during incoming calls. 4. Not limited to UPS function, can be expanded for multiple purposes; Fully charged, it can be used as a low-power mobile power source and a temporary emergency charger for lithium batteries 5. Equipped with a universal TYPE-C charging interface, it can directly input DC5V to charge lithium batteries Parameters: Input: DC 5V Output: 5V/9V/12V optional When outputting 5V: maximum current of 1000mA When outputting 9V: maximum current 500mA When outputting 12V: maximum current of 350mA Attention: The current of the charging power supply should be greater than the output current. Load power: UPS output+- connected load, normal recommended<5W, transient<8W. Module size: 89 * 22 * 22.4mm (back mounted battery box) 89 * 22 * 38.5mm (back inserted into battery box) The diameter of the module installation hole is 3mm Main functions: 1) Lithium battery charging 2) Lithium battery protection (short circuit, overvoltage, undervoltage) 3) Boost output 5v/9v/12v optional 4) Equipped with a universal TYPE-C charging interface, it can directly input DC5V to charge lithium batteries 5) Two color LED indicator light, red light stays on during charging, green light stays on when fully charged, automatically stops charging 6) Principle of UPS uninterrupted power supply function during power outage: When the power is turned on, it directly supplies power to the load through the boost circuit Once the power is cut off, the automatic starting battery supplies power to the load through the boost circuit After the power supply is restored, it not only provides power to the load but also charges the battery 7) Interface description (refer to the above figure): TYPE-C port and standard input 5V+and 5V - are external power supply ports. Choose one of the two. UPS+and UPS - are labeled as output interfaces. Weld the battery box on the back and connect the 18650 lithium battery. You can also solder the wire out to connect other lithium batteries. Notes: Boost board description: The boost section is controlled by a switch to operate and shut down, It can also be directly short circuited through jumper pads. (The switch needs to be self equipped) When used as a UPS, the UPS output switch needs to be short circuited to ensure real-time continuity of the output. The battery can be started at any time when the power is cut off (special attention should be paid to this during use, as many customers forget to short circuit). 2. As a portable power bank, a switch can be added to the UPS output switch interface, which can be turned off when not in use without static losses. If you don't want to connect the switch, you can also short-circuit it. After the test is completed, removing the output indicator light can reduce the current consumption of tens or twenty mA. 3. During use, it is possible that the board may not output due to (accidental touch, wrong connection, short circuit, etc.) entering a protective state (lithium battery overcharge protection, overdischarge protection, current limiting protection, over temperature protection, output short circuit protection). After troubleshooting, connect 5V to the charging port to activate and output again. If the discharge can continue after the power is disconnected, a resistor of about 1K can be connected in parallel to the 5V input port to solve the problem. 5. During welding operations, ensure that the soldering iron is grounded (and the grounding wire is conductive), and it is best to wear anti-static gloves for operation.
