Backup power supply designed for powering circulation pumps or other electrical devices in case of a power outage. The backup power supply ensures the circulation pump of the boiler is powered, preventing it from overheating.

The backup power supply consists of two integrated lead-acid batteries, electronic circuits ensuring battery charging and protection, an inverter, sockets for connecting backed-up devices, and a cable for connecting to the electrical grid. The output voltage has a sinusoidal waveform, allowing for the smooth operation of low-energy circulation pumps - tested with Wilo pumps.

Backup Duration 

• Power consumption of the device at the output (230 V) 20 W backup duration 5 h

• Power consumption of the device at the output (230 V) 45 W backup duration 3 h 30 min

These are indicative times. Dependence on current consumption, battery age, etc.

Features

• Automatic switching from grid to battery power and back

• High inverter efficiency

• Intelligent two-stage battery charging with overcharge protection

• Protection against overload and complete battery discharge

• Multifunctional LED and acoustic signaling

• Very quiet operation due to the absence of a fan
