Backup power supply designed for powering circulation pumps or other electrical devices in the event of a power outage. The backup power supply ensures the circulation pump of the boiler is powered, thus 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) 120 W backup duration 4h 37 minutes

• Power consumption of the device at the output (230 V) 250 W backup duration 2h 31 minutes

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

Features

• Automatic switching from mains to battery power and back

• High inverter efficiency

• Intelligent two-stage battery charging with overcharge protection

• Protection against overload and complete battery discharge

• Noise level < 60 dB
