Estink Super Capacitor UPS PCB Uninterruptible Power Supply 9 to 24V DC Input 5V 3A Output 25F Backup with Power Loss Signal 10 to 60s Hold Up for RPI Data Save (4S)

【Fast Backup Switch】Super capacitor UPS switches to capacitor discharge when external power is lost. It supports 10 to 60 seconds hold up time for RPI data save and controlled shutdown. 【Stable Power Output】Uninterruptible power supply accepts 9 to 24V DC input and delivers 5V 3A output through USB 2.0 or KF128 terminal. Fits embedded boards controllers and compact power setups. 【Power Loss Signal】Built in 2.54mm 2P detection port outputs 3V with external power and 0V on outage. Helps Actuator data storage actions for RPI automation devices and systems. 【Compact PCB Design】PCB module measures about 90 x 56mm with 3.5mm locating holes for mounting. Light and compact format suits control boxes test benches network devices and DIY integration. 【Clear Status Indication】DC IN green shows input connection 5V OUT red shows output status and Vcap green changes brightness with capacitor voltage. Charge current is limited to 1.4A with about 3 minutes full charge. Spec: Item Type: Super Capacitor UPS for RPI Material: PCB Power Input: 9-24VDC (5.5x2.1mm DC power socket or KF128 terminal) Power Output: 5VDC (USB 2.0 or KF128 terminal), maximum current 5V3A Super Capacitor: 25F Charging Current: limited to 1.4A, about 3min to fully charge capacitor Discharge Current: 5V3A (continuous) when connected to external power supply, 5V3A (within 10s) when only super capacitor output Power Down Detection: 2.54mmx2p, 3V indicates external power source, 0V indicates power loss Power Indication: DCIN green indicates external power source connection, 5V OUT red indicates 5V output, Vcap green light brightness changes with capacitor voltage. Brightest when capacitor is full, off when capacitor is discharged Product Size: Approx. 90 x 56mm / 3.5 x 2.2in Locating Hole: Approx. 3.5mm / 0.14in Package List: 1 x Super Capacitor UPS How To Use: Insert external power supply to output 5V and charge
