Usb Modulo Power Bank Ups Salida 12v 18650 Holder Booster Itytarg

 

6) Función de fuente de alimentación ininterrumpida de UPS

 

 

 

 

 

Input: DC5V

(Versión de 5V de salida) Output 5V: current maximum 1A (charging power supply should be greater than 1A current output capability).

(Versión de 12V de salida) Output 12V: Maximum current 350mA (same as above)

Load: Connect the output positive and negative poles to the load.

It is recommended that the normal load is <5W and the transient state is <8W.

VOUT=0.6*(1+R4/R5) VOUT=0.6*(1+R4/10K) R4=(VOUT/0.6-1*10K

Remarks: If it enters the protection state after misoperation and short-circuit, it will not output (overcharge protection, over-disch arge protection, current limit protection, over-temperature protection, output short-circuit protection of lithium battery), it will automatically activate and re-output when connected to 5V charging.

Note: There are Mos and other components on the board, whichare easily damaged by induction or static electricity of the soldering iron. Make sure that the soldering iron used is grounded (and the ground wire is connected). It is best to wear electrostatic gloves.

1. Lithium battery charging

2. Lithium battery protection (short circuit, overvoltage, undervoltage)

3. Boost output 5v / 12v optional

4. Equipped with universal Micro USB charging interface, direct DC5V input to charge the lithium battery

5. The two-color LED indicates the charging status, when the green light is on, the charging will stop  automatically

6. The module is equipped with two high-quality 18650 battery holders to choose from, in-line and patch

7.UPS uninterrupted power supply function When the power supply has power, the power supply is directly supplied by the power supply through the booster circuit. Once the power supply is powered off, the battery path is automatically started to supply power to the load via the booster circuit. The power supply from the power supply to the load is restored Also charge the battery

Description of the booster board: the booster part uses switches to control its operation and shut down, and it can also be shorted directly through the jumper pad. (The switch needs to be equipped separately)

1. When used as a UPS, the UPS output switch needs to be short-circuited, the output remains on in real time, and the battery can be started at any time when the power is turned off,

2. As a mobile power supply, you can add a switch to the UPS output switch interface, turn off when not in use, there is no static |oss, and it is very power-saving.

3. If the UPS output switch interface does not want to be connected to the switch, it can also be short-circuited, and after the test is completed, the output indicator is soldered down, which can reduce the current consumption of more than ten or twenty mA and does not affect the normal output of the circuit. .

4. During the operation process, the board may enter the protection state without output due to various reasons (mis-touch, wrong connection, etc.). After removing the problem, the board charging port can be connected to 5V to charge. Re-output can be activated.

5. The 5V charging power supply used by individual users uses a larger capacitance output capacitor. This capacitor can continue t0 discharge after the power supply is turned off, so that the power supply voltage has a slow down process, which will cause the board to shut down after the power supply is turned off. There is
no rapid switching of battery power. If you encounter such a situation, you can connect a discharge resistor of about 1K in paralle| to the 5V input port.
