KEMOT PROavr-45k automatický trojfázový stabilizátor napätia 45 kVA

Voltage fluctuations in three-phase installations can damage sensitive equipment, cause production downtime, and increase energy costs. The KEMOT PROavr-45k automatic three-phase voltage stabilizer solves this by maintaining a stable 380 V AC output even when input voltage varies between 280 V and 430 V. With a robust 45 kVA power rating and servo motor technology, it is built for industrial and commercial environments where reliable power is non-negotiable.

Who is it for

This stabilizer is ideal for factories, workshops, server rooms, medical facilities, and any site with three-phase machinery that requires consistent voltage. It protects CNC machines, compressors, HVAC systems, and IT infrastructure from overvoltage, undervoltage, and short circuits, extending equipment lifespan and reducing repair costs.
