The  Power Sinus 3000 12 V UPS is a combination of an inverter, a charger and an automatic AC switch in a single circuit. It is primarily intended as a Pure Sinus voltage waveform UPS. It is used wherever a stable voltage and very high starting current of 3000W is required, including 9000VA instantaneous (up to 20 seconds). One of the advantages of the  Power Sinus 3000 12 V is the possibility to connect different types of 12V batteries.

Which devices can be powered by the  Power Sinus 3000 12 V power supply?

Refrigerators
Freezers
Air compressors
Caravans
CH pumps
CO cookers
Doors
Solar panel systems
Safety features:

Overload
Overheating protection
Undervoltage
Short circuit
Battery overload
What makes  Power Sinus 3000 12 V UPS different from other UPSs?

The pure SINUS UPS generates a "sinusoidal" voltage at its output, just like on the mains. As a result, it can power inductive devices (such as power tools, air compressors, air conditioners, refrigerators, freezers, etc.).
