Description

• DC 12V 12W UPS uninterruptible power supply control board, used to design routers, switches and other network equipment or infrared alarms for continuous power supply, the battery is fully charged when the upper limit can output 1A current, the battery voltage is about to empty can output 8-9W power, automatic shutdown when the output is short-circuited, after charging again to recover, the battery is empty before shutdown regular flashing prompt, flashing several times after entering the low power protection and shutdown Output! (Tip: input or output interface can be common negative, positive pole can not be shared, the battery side can not be common negative!)

Reminder

• The current motherboard has a charging time detection function, the default slow charging for batteries within 8Ah, change the jumper for fast charging for batteries within 8-15Ah.

Application

• Developed for 12V 1.5A router or light cat and high-power UPS uninterruptible power supply motherboard, but also can be used for 12V 1A devices!

Product description

• Input voltage: DC 5V-12V (this voltage is the voltage when charging the battery)
• Output voltage: DC9V or DC12V can be selected
• Output power: MAX 12W
• Board size:50206mm

Please note

• BAT wiring please last step before connecting the battery, this is very important, battery 3.7V lithium or polymer batteries, battery capacity: 1-3AH (MAX 5AH)
• Welding input and output at least 20AWG line, the line length should not exceed 10CM
• Input if connected to the output will form a loop, the loop will lose 0.4-0.6mA current
• The output of the control board is not valid for short circuit when charging, so please use this function carefully!
• The control board will be hot when working, so the installation should be kept at a certain distance from the battery!
