3.7V Lithium Battery DC UPS Uninterruptible Module Charging and Discharging Boost 9V12V Power Outage BoostItem NO.: MK00544

DC UPS Uninterruptible Module 9V12V

Product Description:

● Input voltage: DC5V-12V (this voltage is the voltage used to charge the battery)

● Output voltage: DC9V or DC12V can be selected (default is 9V, or you can change the jumper setting to 12V yourself. In addition, the output voltage is the voltage when only using battery power. If there is a charging input, the output will be equal to the input)

● Output power: MAX 12W

● Board size: 50 * 20 * 6mm

● DC UPS 12V 12W UPS uninterruptible power supply control motherboard, used for designing continuous power supply for network devices such as routers, switches, or infrared alarms. When the battery is fully charged, the upper limit can output 1A current, and when the battery voltage is about to empty, it can output 8-9W power. When the output is short circuited, it automatically shuts down and recovers after recharging. Before the battery is emptied and shut down, a flashing prompt often appears. After flashing several times, it enters low battery protection and turns off the output! (Reminder: Input or output interfaces can share negative electrodes, positive electrodes cannot be shared, and battery terminals cannot share negative electrodes!)

● Reminder: The current motherboard has a charging time detection function. The default slow charging is suitable for batteries within 8Ah, and the jumper is changed to fast charging for batteries within 8-15Ah.

● High power UPS uninterruptible power supply motherboard developed for 12V 1.5A routers or optical cats, and can also be used for 12V 1A devices!

● When charging, a minimum input of 5V is required, and the default charging current is 0.5-0.6A. The customer's original charger does not need to be replaced, and there is also a jumper to improve the charging speed. If the charging is accelerated, the customer's original power supply must be replaced to prevent safety hazards. At least double the power is necessary. For example, if the customer is using a 12V 1.5A power supply, if the charging is fast, it needs to be replaced with a 12V 2.5A-3A power supply, and more margin needs to be reserved, Because you cannot know if the quality of the power supply meets the standard! Please pay attention to this issue for all colleagues or users!

● BAT requires the last step to connect the battery, which is very important. The battery is a 3.7V lithium or polymer battery with a capacity of 1-3AH (MAX 5AH)

● Note: Welding input and output should use at least 20AWG wire, and the wire length should not exceed 10CM

● If the input is connected to the output, it will form a loop, which will lose 0.4-0.6mA of current

Application Instructions for Accessories of Charging Indicator Light:

Indicator light: A red emitting blue diode with a common anode. The blue light indicates whether it is loaded; The red light indicates whether the battery is charging, the charging red light is on, and the fully charged red light is not on; A flashing red light indicates that the battery is abnormal or not connected. The indicator light needs to be configured independently. It is recommended to choose a red and blue indicator light to be effective, while other dual color indicator lights are invalid.

Attention: The output short circuit of the control board is invalid during charging, so please use this function with caution!

Attention: The control board may generate heat during operation, so it should be installed at a certain distance from the battery!
