DC UPS 9V 12W UPS power failure current control board, used for designing continuous power supply of routers, switches and other network equipment or infrared alarms. When the battery is fully charged, the upper can produce 1A. When the battery voltage is about to be discharged, it can output 8-9W. When the output is short-circuited, it will automatically shut down. After charging, it will be restored. Before the battery is discharged and shut down, a flashing prompt will often appear and enter low protection after flashing several times. and shut off the output!Tips: Input or output interfaces can share negative poles, positive poles cannot share negative poles, and battery poles cannot share negative poles! A High UPS power failure power supply motherboard developed for 9V 1.5A routers or optics, and can also be used for 9V 1A equipment! Minimum 5V input is required for charging. Type: power failure inverter Input Voltage: DC5V-12V (this voltage is the voltage when charging the battery) Output Voltage: DC9V Output: MAX 12W Color: green Material: PCB Size: 50 x 20 x 6 mm Package Contents: 1 module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture to differ slightly from the real one. The allowed measurement error is +/- 1-3 cm.
