Description

DC UPS 12V 12W UPS uninterruptable power control motherboard, used for the design of routers, switches and other network equipment or infrared alarm continuous power supply, when the battery is fully charged, the upper limit can output 1A current, battery voltage is about to be empty can output 8-9W power, output short circuit when the automatic shutdown, again after charging recovery, The battery often appears flashing before shutdown, flicker several times into low power protection and shut down the output! (Tip: Input or output interface can share negative electrode, positive electrode cannot share, battery side cannot share negative electrode!)

Reminder: the current motherboard has charging time detection function, the default slow charge is suitable for 8Ah battery, change jumper for fast charge is suitable for 8-15Ah battery.

High power UPS uninterruptible power supply motherboard developed for 12V 1.5A router or optical cat, but also can be used for 12V 1A devices!

Charging requires the minimum input of 5V, the default charging current 0.5-0.6A can not replace the customer’s original charger, and another jumper can improve the charging speed, if it is accelerated charging must replace the customer’s original power supply, to prevent safety risks, at least double the power can be, such as the customer is using 12V 1.5A power supply, If you charge fast, you need to change to 12V 2.5A-3A power supply, you need to keep more spare, because you have no way to know whether the quality of the power supply is up to standard! Please each peer or user attention to this problem!

Product Description:

Input voltage: DC5V-12V (This voltage is the voltage when charging the battery)

Output voltage: DC9V or DC12V can be selected (the default is 9V, you can also change the jumper set to 12V by yourself. In addition, the output voltage is the voltage of battery power supply only. If there is charging input, the output will be equal to the input)

Output power: MAX 12W

Plate size :50*20*6mm

BAT please connect the battery at the last step, this is very important battery 3.7V lithium or polymer battery, battery capacity: 1-3AH(MAX 5AH)

Note: At least 20AWG wire should be used for welding input and output, and the wire length should not exceed 10CM

If the input is connected to the output, a loop will be formed, and the loop will lose 0.4-0.6mA current

Accessories for charging indicator:

Indicator light: with common anode red light emitting blue diode. Blue light indicates whether to carry; The red light indicates whether the battery is charged. If the battery is fully charged, the red light is on. Blinking red The battery is abnormal or not connected to the battery. Indicators need to be configured by yourself. Red and blue indicators are recommended to be effective. Other colors are invalid.

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

Note: The control panel will heat up when working, so it should be installed at a certain distance from the battery!
