DC UPS 12V 12W UPS uninterruptible power supply control board, used to design routers, switches and other network equipment or infrared alarms for continuous power supply. When the battery is full, the upper limit can output 1A current. When the battery voltage is about to be empty, it can output 8-9W Power, when the output is short-circuited, it will automatically shut down, and it will be restored after recharging. Before the battery is emptied and shut down, there will be a flashing prompt. After flashing several times, it will enter the low-power protection and turn off the output! (Reminder: The input or output interface can share the negative electrode, the positive electrode cannot be shared, and the battery terminal cannot share the negative electrode!)
Reminder: The current motherboard has a charging time detection function. The default slow charge is suitable for batteries within 8Ah. When the jumper is changed to fast charging, it is suitable for batteries within 8-15Ah.
The high-power UPS uninterruptible power supply motherboard developed for 12V 1.5A routers or optical modems can also be used for 12V 1A equipment!
When charging, a minimum input of 5V is required, and the default charging current is 0.5-0.6A. You don’t need to replace the customer’s original charger. There is also a jumper to increase the charging speed. If the charging is accelerated, the customer’s original power supply must be replaced to prevent potential safety hazards. Double the power. For example, if the customer is using a 12V 1.5A power supply, if you charge quickly, you need to change to a 12V 2.5A-3A power supply. You need to keep more margin, because you have no way to know whether the quality of the power supply is up to standard. ! Please pay attention to this problem!
Product description:
Input voltage: DC 5V-12V (this voltage is the voltage when charging the battery)
Output voltage: DC 9V or DC 12V can be selected (default is 9V, you can also change the jumper to set to 12V, and the output voltage is the voltage when only battery power is used, if there is a charging input, the output will be equal to the input)
Output power: MAX 12W
Board size: 50*20*6mm
BAT connection is the last step before connecting the battery. This is very important. Battery 3.7V lithium battery 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
Application description of accessories for charging indicator:
Indicator light: red light-emitting blue diode with common anode. The blue light indicates whether the battery is loaded; the red light indicates whether the battery is charged, the charging red light is on, and the red light is off when it is fully charged; the red light flashing indicates that the battery is abnormal or the battery is not connected. The indicator light needs to be configured by itself. It is recommended to select the red and blue indicator light to be effective, and other color two-color indicators 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 board will heat up when it is working, so keep a certain distance from the battery when installing!
