VOLT POLSKA AVR 500 Voltage Stabilizer 500VA

With a response time under one second and an efficiency rating above 95%, the VOLT POLSKA AVR 500 keeps your equipment running smoothly even when mains voltage fluctuates. This relay-type stabilizer accepts a wide 140–260 VAC input and delivers a stable 230 V output, making it a dependable first line of defense for home electronics, computers, and small appliances.

Overview

The AVR 500 is a single-phase automatic voltage regulator built around a reliable relay switching circuit. It continuously monitors incoming voltage and corrects deviations to keep the output within ±3% of the ideal 230 V. Whether you're dealing with brownouts, surges, or erratic grid conditions, this stabilizer keeps your devices powered safely and consistently. Simple to set up—plug the fixed power cord into your wall outlet and connect your appliances to the two Schuko outlets. No complex wiring required.

What stands out

• Fast stabilization: Corrections in less than one second protect against sudden voltage spikes and dips.
• High efficiency: With over 95% efficiency, minimal energy is wasted as heat.
• Flexible delay: Selectable 6-second or 180-second start delay prevents compressor and motor damage after power cuts.
• Comprehensive protection: Safeguards against overload, short circuit, over/under voltage, and overheating.
• Two Schuko outlets: Power two devices directly from the stabilizer.
