Backup power source designed to power circulation pumps or other electrical equipment in the event of a power failure. The back-up source provides power to the boiler's circulation pump and thus prevents it from overheating.

The backup source consists of two integrated lead-acid batteries, electronic circuits ensuring the charging of the batteries and their protection, an inverter, sockets for connecting backed-up devices and a cable for connecting to the electrical network. The output voltage has a sinusoidal course and thanks to this it enables trouble-free operation of low-energy circulation pumps - tested with Wilo pumps.

Backup time

• Power consumption of the appliance at the output (230 V) 120 W backup time 4h 37 minutes

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

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

Properties

• 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
