Description: KEMOT PROsinus-300 Uninterruptible Power Supply. It is an inverter with a pure sine wave output and also features a charging function. Designed to power various consumers at a nominal voltage of 230VAC with a maximum power of 300W, such as:

• central heating pumps, fireplaces
• other devices requiring a maximum power of 300W (500W peak)

Due to the pure sine wave output, it ensures stable operation of the load and does not cause overheating of inductive loads such as pumps or fans. Together with a 12V battery, it forms a complete uninterruptible power supply unit of 230VAC. It features protection against battery overcharge, short circuit, overvoltage, protection from excessively high or low battery voltage, and overheating protection.

The device can operate in three modes:

1. As an uninterruptible power supply with charging function - allows the passage of voltage from the network to the load and charges the external 12 VDC battery.
2. As a rectifier - charges the external battery (the device must be connected to the 230V AC source).
3. As an inverter - converts the 12V DC voltage from the external battery to variable AC voltage 230V.

The device is equipped with a clean and transparent LED display, indicating the operating status:
