Features:

This product is designed for uninterrupted power supply during outages. It utilizes external power when available and automatically switches to battery power seamlessly during power failures.

Type-C interface supports significantly higher current than microUSB, with a maximum capacity of 5A.

Ideal for routers, cameras, development boards, and similar devices, ensuring uninterrupted connectivity during power outages.

Seamless switching between external power and battery (zero delay). Uninterrupted power supply: auto-starts during outages and auto-charges when power returns.

Selectable output voltages: 5V/9V/12V.

Four practical functions: lithium battery charging, lithium battery protection, boost output, and UPS switching.

Dual-color LED indicates charging status: steady green light when fully charged, auto-stops charging.

Type-C port supports high current flow.

Product Specifications:

Output Voltage: 5V/9V/12V

Current: 5A (Max)

Port: Type-C port

Peak Power: Up to 20W

Rated Power: Up to 15W

Module Dimensions: 88*41*22mm (LxWxH) (with back panel mounting box)

Function Description:

1. UPS Function: When mains power is available, it directly supplies the load via the boost circuit while charging the lithium battery. Upon power failure, the battery path automatically activates to supply the load via the boost circuit.

2. Boost Circuit: Peak power up to 20W, rated power up to 15W. BOST boost circuit with built-in 12A high-current MOSFET. Efficiency up to 96%. Module static power consumption: 25mA. Selectable outputs: 5V/9V/12V. (Recommended load <15W under normal conditions. Outputs: 5V: 3A, 9V: 1.6A, 12V: 1.2A)

3. Lithium Battery Protection: Overcharge, over-discharge, over-temperature, and overcurrent protection. (If short-circuited due to misoperation, it enters protection mode without output. Connecting to 5V charging automatically reactivates output.)

Instructions:

1. The USB port and ports labeled 5V+ and 5V- serve as external power supply ports; either one can be used. Ports labeled USP+ and USP- are the output ports. Solder the battery box to the back and connect an 18650 lithium battery. Other 3.7V lithium batteries can also be used.

2. When used as a UPS, install the battery to ensure the 5V input power supply has sufficient capacity. The output remains continuously active, and the battery can immediately take over power supply upon input power failure.

3. To conserve energy in UPS mode, desolder the output indicator LED after testing completes. This reduces current consumption by over ten mA without affecting normal output, significantly saving power.

4. During operation, accidental touches or incorrect connections may trigger the board's protection mode, halting output. After troubleshooting, briefly apply 5V charging voltage to the board's charging port. This will reset the board and reactivate output.

5. Some 5V charging power supplies use high-capacitance output capacitors. These capacitors continue discharging after power loss, causing a gradual voltage drop. This may delay the board's switch to battery power after shutdown. If encountered, connect a 1KΩ discharge resistor in parallel with the 5V input port.

6. To increase the UPS module's battery capacity, multiple cells can be connected in parallel without affecting other functions.

Important Notes:

1. Components like MOSFETs on the board are susceptible to damage from soldering iron induction or static electricity. Ensure your soldering iron is grounded (with the power strip's ground wire connected) and wear anti-static gloves during operation.

2. When installing batteries, ensure they are not reversed, as this may burn the board.

3. Select a power supply with sufficient capacity to ensure normal board operation.

4. Do not supply the board with voltage exceeding 5V.

5. Unauthorized modifications to the board without technical verification will void technical support and after-sales service.

6. Heat generation during high-power operation is normal; adequate heat dissipation is required.
