Type-C 15W 3A 18650 Lithium Battery Step-up Charger Module Fast Charge UPS High Power Supply Converter 5V 9V 12V
UPS-15W
module can realize the seamless switching of external power supply and
battery dual power supply (no delay), suitable for uninterrupted power
supply schemes such as low-power DC equipment and meters, and self-start
after power failure and self-charge when power is received.
The
UPS-15W module integrates four practical functions of lithium battery
charging, lithium battery protection, boost output, and UPS switching.
It is also equipped with a universal Micro USB charging interface,
direct DC5V input to charge the lithium battery, two-color LED indicates
the charging status, and the full green light Always on, automatically
stop charging, the module is equipped with two high-quality 18650
battery holders to choose from.
Function description:
1.
UPS function: When the power supply is powered on, the power supply
directly supplies power to the load via the booster circuit, and
simultaneously charges the lithium battery. Once the power is cut off,
the battery path is automatically activated to supply power to the load
via the boost circuit.
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. (The load is
recommended to be 15W under normal conditions. Output 5V: current
3A, output 9V: current 1.6A, output 12V: current 1.2A)
3.
Lithium battery protection: over-charge, over-discharge,
over-temperature, over-current protection (if it enters the protection
state and does not output after a short-circuit by mistake, it will
automatically activate and restore output when connected to 5V
charging).
4. Module size: 89*42*22.4mm (back patch battery box)
Instructions for use:
1.
When used as a UPS, it is necessary to install a battery to ensure that
the input 5V power supply has sufficient power, and the output is kept
on in real time, and the battery can be started at any time when the
power is off.
2.
If the UPS wants to save energy consumption, solder down the output
indicator after all tests are completed, which can reduce the current
consumption of more than ten mA without affecting the normal output of
the circuit, which is more power-saving.
3.
During the use and operation, the board may be triggered to enter the
protection state without output due to various reasons (incorrect touch,
wrong connection, etc.). After troubleshooting, connect the board's
charging port to 5V for charging, and the board is powered on again.
Re-output can be activated.
4.
The 5V charging power supply used by individual users uses a relatively
large output capacitor. This capacitor can continue to discharge after
the power is turned off, so that the power supply voltage has a slow
drop process, which will cause the board after the power is turned off.
Did not switch battery power quickly. If you encounter such a situation,
you can connect a 1K discharge resistor in parallel to the 5V input
port.
5.
If you want to increase the battery capacity of the UPS module, you can
use multiple cells in parallel, and other functions will not be
affected.
