Description:
Small ups is an alternative energy storage power supply. Reliable PCB lithium battery safety and environmental protection, cheat current / constant current / constant voltage lithium battery charging BMS is created by high performance DC-DC high efficiency, surge and circuit breaker. The small UPS has perfect charge discharge and over-current protection functions, which can prevent short circuit.

Application:
Intelligent Mini UPS 12V is widely used in fingerprint attendance machine, fire safety monitoring system, emergency lighting alarm system, personal communication system, portable digital camera, Bluetooth device, CD machine, MD machine, portable DVD machine, smart card MP3 player, etc.

Rated capacity: 57.72 w
Input voltage: 12V ± 5%
Input current: 2002000 Ma
Output voltage: 12V ± 5%
Output current: 2002000ma
Temperature: 20 - 65 ℃
Net weight: 405 G
Volume: 111 x60x43mm working

Conditions:
Loading: 0-55 ℃
Discharge temperature: - 20-65 ℃
30 days storage: - 20-45 ℃
90 days storage: - 20-35 ℃

If it does not cooperate for a long time, micro UPS must be stored in a cool and dry place.

Or the performance will be reduced due to the reverse connection with the equipment;

Storage:
After storage, the ups will be self discharged under the influence of extremely high ambient temperature. Therefore, UPS should be fully powered when it is stored. If it is stored for a long time, it should be loaded regularly to avoid losing its original capacity.

Safety precautions:
Will not expose small ups in rain or snow;
Do not turn the small heat source from the fire or heater, such as "off" or turn the small ups;
DC cable connection is wrong.
Power adapter error;
The equipment voltage should be consistent with the corresponding micro UPS voltage
Please keep these little things away from the children.

Tips:

The charging current is only about 0.24A

Need 50 hours

Our product belongs to indoor charging and using products

If the charging current is designed to be large, the adapter on the customer’s original device cannot be supplied, causing the device to work abnormally

Adapter current = equipment + UPS charging current

Originally, the adapter on the device provides one-to-one power supply to the device. Now that a UPS is added in the middle, the adapter’s current is also required, so the UPS cannot have a large current.

You can only use the adapter to power the device and the remaining little current to charge the UPS

The UPS charging current is greater than the remaining current. The power supply of the adapter is insufficient, causing the equipment to work abnormally.

Usually the red light is on, because the charging current is very small and the power consumption is also at the same time, so it is difficult to 100% saturation

If some 12v2A devices have the highest power consumption, such as 12v1.85A, the UPS may be green at this time because the power supply of the device is abnormal.

You need to unplug the UPS charging port. After two or three minutes, plug it in and it will be normal again.
