Qoltec 50722 Automatic Voltage Stabilizer AVR 500VA 300W

The Qoltec 50722 Automatic Voltage Stabilizer AVR 500VA ensures stable voltage supply for your sensitive devices, especially when used with generators or unstable mains. It combines voltage stabilization and surge protection in a compact, portable unit.

Advantages

Protects your equipment from voltage fluctuations, overloads, short circuits, and overheating. The built-in LCD display shows real-time parameters, and the delay function (adjustable up to 180 seconds) prevents damage to motors and compressors from rapid cycling.

Suitable for

• Power tools in gardens, construction sites, garages
• Food trucks, camper trailers, and other mobile applications
• Any location with unstable mains or generator power
