The URZ3411 is a solution for an external backup power supply Kemot PROsinus-1600W, designed to protect selected devices from power disturbances that may affect their operation.

It is ideal for operating central heating pumps, fireplace system pumps, induction motors, and other sensitive devices that require stable power supply without distortions. Its output provides a pure sine wave voltage, ensuring stable operation and preventing overheating of inductive loads.

The unit features battery protection against overcharging, short circuit, overvoltage, as well as high or low voltage and overheating. It is suitable for:

• Necessary power supply for heating radiators
• RTV devices (televisions, receivers, hi-fi, DVD)
• AGD devices (refrigerators, blenders)
• Electric tools (drills, angle grinders)
• Chargers (smartphones, tablets, laptops)
• Pumps and compressors (water, heating, air conditioning)
• Office devices (fax, computers, monitors)

The device can operate in three modes:

• As a backup power source with charging capability, it converts 12V DC voltage from an external battery to 230V AC and charges the battery.
• As a battery charger, it provides charging to an external battery (requires connection to the 230V AC network).
• As an inverter, it converts 12V DC from an external battery to 230V AC.

The URZ3411 features a pure sine wave output and an LED display that shows:

• Input voltage
• Output voltage and frequency
• Charging level
• Loading level
