3A 5V 9V 12V 18650 Li-ion Battery Charging Module UPS Power Supply Module Type-c

 
Product Features:
This product is suitable for non-stop application of power outage equipment, using external power supply when there is power, and automatically and seamlessly switch to battery power when there is power outage.
Type-c interface power supply, relative to microUSB interface, can pass through a much larger current, up to 5A.
Suitable for routers, cameras, development boards and other devices, seamlessly switch to battery power when the power is off, no network when the power is off
Seamless switching of external power supply and battery dual power supply (no delay). Uninterrupted power supply, self-starting in case of power failure, self-charging in case of call.
Output voltage 5V/9V/12V can be selected.
Four practical functions: Li-ion battery charging, Li-ion battery protection, boost output, and UPS switching.
Two-color LED indication of charging status, full green light is always on, automatically stop charging.
Type-C interface, high through current.
Product parameters:
Output voltage: 5V/9V/12V
Current: 5A (max)
Interface: Type-c interface
Peak power: up to 20W
Rated power: up to 15W
Module size:88*41*22mm length, width and height (back patch box)
Function description:
1, UPS function: when the power supply has power directly from the power supply through the boost circuit to the load power supply, while charging the lithium battery. But once the power is off, automatically start the battery path through the booster circuit to the load power supply.
2、Boost circuit: peak power up to 20W, rated power up to 15W, BOST boost circuit, built-in 12A high current MOS, efficiency up to 96%, module static power consumption 25mA, optional 5V/9V/12V output. (Load normals are recommended <15W. Output 5V: current 3A Output 9V: current 1.6A Output 12V: current 1.2A )
3, lithium battery protection: overshoot, overdischarge, over temperature, over current protection (if the misoperation of the short circuit into the protection state does not output, access to 5V charging automatically activated to restore the output).
Instructions for use:
1, USB port and standard 5V +, 5V - for the external power supply port, the 2 choose one of them can. Marked USP+ and UPS- for the output interface. Back welding battery box connected to 18650 lithium battery. Can also be connected to other 3.7V lithium batteries.
2, used as a UPS, you need to install the battery to ensure that the input 5V power supply has sufficient power, the output is kept on in real time, power failure can always start the battery power.
3, if the UPS wants to save energy, all tests are completed to weld down the output indicator, which can reduce the current consumption of more than a dozen mA and does not affect the normal output of the circuit, more power saving.
4, the use of the operation process may be due to a variety of reasons (mistaken touch, misconnection, etc.) trigger the board into a protective state not output, you can exclude the problem to the board charging port access to 5V charging, the board can be re-energized to activate the re-output.
5, individual users use the 5V charging power supply internal use of large capacitance output capacitor, this capacitor can continue to discharge after the power failure, so that the power supply voltage has a slow drop process, which will cause the power off the board did not quickly switch the battery power. If you encounter such a situation, the 5V input port and connected to a discharge resistor of about 1K.
6, if you want to increase the UPS module battery capacity can be used in parallel with multiple sections, other functions are not affected.
Cautions:
1, the board has MOS and other components, easy to be inducted by the soldering iron or electrostatic damage, please ensure that the use of the soldering iron has a ground (and plug ground conductivity), it is best to wear anti-static gloves to operate.
2, the installation of the battery must be careful not to install the reverse, otherwise it will burn the board.
3, please choose enough power supply power supply. To ensure that the board works properly.
4, the board power supply should not be higher than 5V.
5, the board without technical confirmation, private changes. The store is not responsible for technical support and after-sales.
6, the module high-power work when the heat is normal, pay attention to the fan heat is good.
