Pure Sine Thermal Central UPS 800VA/500W 12V – KEMOT URZ3405

KEMOT URZ3405 uninterruptible power supply. It is an inverter with pure sine output and it also has a charging function
It is designed to supply various consumers at a nominal voltage of 230 VAC and having a maximum power of 500W, such as:

– pump for central heating, fireplaces
– other devices that require a maximum power of 500W (800W peak)

Due to the pure sine type output voltage, the device ensures the 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 unit for 230 VAC supply. It is equipped with battery overcharge protection, short circuit, overvoltage protection, battery voltage protection that is too high or too low, and overheating protection.

The device can work in three modes:

1. As an uninterruptible power supply with charging function – let the mains voltage pass to the load and charge the external 12 VDC battery
2. As a rectifier – charges the external battery (the device must be connected to the 230V AC power supply)
3. As a converter – converts the DC voltage of 12V DC external battery served with a variable voltage AC 230V

The device is equipped with a clear and transparent screen with LEDs, indicating the operating status:

• feeding
  – Input voltage
  – Voltage and frequency of the output signal
  – Battery charge level

IMPORTANT FOR USE:

– to start the inverter, the red button must be set to the ON position and the inverter will start AUTOMATICALLY, without pressing any other button.

The battery for the UPS is not included.
