Product Highlights
- 【instructions for use-1】 ✔1. when used as a ups, a battery must be installed to ensure that the 5v input power supply has sufficient power, the output remains active in real time, and the battery can be started at any time when turned off.
- 【instructions for use-3】 ✔3. during use and operation, the card may be triggered to enter the dead-end protection state due to various reasons (wrong touch, wrong connection, etc.). after solving the problem, connect the card's charging port to 5v to charge and the card will turn on again. retransmission can be activated.
- 【5v2b ups box】this ups-15w module can realize the perfect switching of external power supply and dual battery. power supply (no delay), suitable for uninterrupted power schemes such as low-power dc equipment and meters, and automatic start after power failure and automatic recharge when power is received.
- 【instructions for use-2】 ✔2. if the ups wants to save power consumption, please solder the output indicator after completing all tests, which can reduce the current consumption by more than ten ma without affecting the normal output of the circuit, thus saving more energy.
- 【instructions for use-4】 ✔4. the 5v charging power supply used by individual users uses a relatively large output capacitor. this capacitor may continue to discharge after turning off the power, so the supply voltage has a slow decay process, which will cause the board to turn off after the power is turned off.
