Description UPS uninterruptible power supply board for Raspberry Pi, DC 9-24V input, 5V 3A output, with power outage and surge protection. UPS uninterruptible power supply board for Raspberry Pi, DC 9-24V input, 5V 3A output, with power outage and surge protection. UPS uninterruptible power supply board for Raspberry Pi, DC 9-24V input, 5V 3A output, with power outage and surge protection. Designed for high-reliability applications, it quickly switches to supercapacitor discharge mode when the external power supply unexpectedly stops. It provides a power outage duration of 10-60 seconds and outputs an external power outage signal, sufficient for on-site data storage needs. Specifications: Power Input: 9-24V DC (5.5*2.1mm DC power socket or KF128 terminal) Output Current: 5V DC (USB2.0 or KF128 terminal), maximum current 5V 3A Supercapacitor: 25F 2-in-1 series Charging current limited to 1.4A, full charge takes approximately 3 minutes Product Dimensions: 90*56mm Positioning Hole: 3.5mm Discharge Current: 5V 3A (continuous); when connected to an external power source, the supercapacitor only outputs 5V 3A (within 10 seconds) Power Off Detection: 2.54mm x 2p, 3V indicates normal external power supply, 0V indicates external power supply failure. Note: 1. Due to differences in lighting and screen, the product color may be slightly different from the picture. 2. Please allow for an error of 1mm-1cm due to manual measurement.
