UPS Pure sine for computers, heating systems, electronics 500VA/300W (external battery) - URZ3404B

KEMOT prosinus-300 pure sine wave backup power supply with charging function.
It is designed to supply AC loads with a nominal voltage of 230 VAC and a power of 300 W, for example:

Central heating pumps
Induction pumps
Fireplace pumps
Automation for thermal convectors
Other devices up to 300W
Thanks to the pure sinusoidal output voltage (load supply), the device ensures stable operation without overheating even when supplying inductive loads such as pumps or fans. Using a 12V battery, it provides full uninterrupted 230V AC power. It contains a battery protection system against overload, short circuit, overvoltage and overheating.

The device can operate in three modes:

Emergency power supply with charging function - converts the 12V DC voltage from an external battery into 230V AC and charges the external battery at the same time.
As a rectifier - charges an external battery (the device must be connected to AC 230V)
As a converter - converts 12V DC from an external battery to 230V AC.
The device is equipped with a clear and transparent LED display with current status indicators.
