Raspberry Pi supercapacitor UPS power failure preservation uninterruptible power supply 5V 3A output

==About==

Specially designed for high reliability scenarios, it will quickly switch to supercapacitor discharge when the external power supply unexpectedly loses power. It can provide a power down battery life of 10-60 seconds and output an external power down signal, which is sufficient for on-site data storage.

==Introduction and Explanation==

Size: 90 * 56 * 26mm/44g (positioning hole: 3.5mm)

==Functional Features==

*Power input: 9~24V DC (5.5 * 2.1mm DC power socket or KF128 terminal block)
*Power output: 5V DC (USB 2.0 or KF128 terminal), maximum current 5V 3A
*Supercapacitors: 25F 2 strings
*Charging current: limited to 1.4A, it takes about 3 minutes to fully charge the capacitor
*Discharge current: 5V3A (continuous) when connected to an external power source, only the supercapacitor outputs 5V3A (within 10 seconds)
*Power failure detection: 2.54mm * 2p, 3V indicates external power supply, 0V indicates external power supply failure.
*Power indicator:
**DC-IN green indicates connection to external power supply
**5V_OUT red indicates that 5V is outputting
**The brightness of Vcap green light varies with the capacitor voltage. When the capacitor is fully charged, it is the brightest; when the capacitor loses power, it goes out

==Instructions for use==

Inserting an external power supply can output 5V and charge the supercapacitor at the same time 

The higher the voltage of the supercapacitor, the brighter the Vcap green LED 

Expected to be fully charged in 3 minutes, with 2 supercapacitors charging at 5.4V and a single capacitor charging at 2.7V 

If the external power supply is disconnected, the DC-IN red LED will turn off after the external power supply capacitor is discharged, and the DC-IN signal on the terminal will also change from 3V to 0V 

At this point, the supercapacitor will rapidly discharge, maintaining the output voltage at 5V. The holding time of 5V is negatively correlated with the output current 

The larger the output current, the shorter the 5V holding time. Under 3A conditions, it can only last for 5-6 seconds, and under very low current conditions, it can even last for several minutes or more. 

==Application scenarios==

This product is suitable for the following scenarios: 

'''Portable devices and field operations:''' 

In field operations or environments without stable power supply, such as geological exploration, outdoor construction, etc., this module can provide real-time 5V DC power to the equipment, while storing energy through supercapacitors to ensure that the equipment can still operate when external power is unavailable 

'''Emergency lighting system:''' 

In public places such as shopping malls and office buildings, emergency lighting systems need to quickly switch to backup power when the main power supply is cut off. This module can quickly provide 5V DC power after the external power is disconnected, maintain the operation of lighting equipment, and ensure the safe evacuation of personnel 

'''Vehicle electronic devices:''' 

For electronic devices such as car navigation and surveillance cameras, the vehicle battery may run low due to prolonged parking. This module can serve as a backup power source for onboard devices. When the vehicle battery is low, the supercapacitor quickly discharges to maintain normal device operation until the vehicle battery is recharged
