KEMOT SER-500-W Stabilizzatore di tensione automatico 500VA 300W 230V AC tipo relè con presa Schuko, precisione ±8%, protezione da sovraccarico e cortocircuito

Voltage fluctuations can damage sensitive electronics, cause data loss, or shorten the lifespan of appliances. The KEMOT SER-500-W Automatic Voltage Stabilizer provides a stable 230 V AC output from an input range of 150–270 V AC, ensuring your devices operate safely even when the mains supply is unstable. With a power capacity of 500 VA (300 W) and ±8% output voltage precision, it is ideal for protecting computers, audio/video equipment, and small household appliances.

Who is it for

This stabilizer is perfect for home users, small offices, and anyone in areas with frequent voltage sags or surges. It suits devices with a combined power consumption up to 300 W, such as desktop PCs, monitors, routers, gaming consoles, and small refrigerators.

Tips

To ensure optimal performance, place the stabilizer in a well-ventilated area and avoid covering the cooling vents. For devices with motors or compressors, use the 180-second start-up delay to prevent damage from frequent power cycles. Always check that the total power consumption of connected devices does not exceed 300 W.
