Product details

This AC automatic voltage regulator employs self-coupling transformer winding technology, enabling it to adjust the output voltage directly for optimal performance. The stabilizer supports dual output voltage options of 110V and 220V, catering to a wide range of appliances and equipment. Its high precision output of AC 220V±5% at both 50Hz and 60Hz ensures that your sensitive devices receive the stable power they require to function properly, minimizing the risk of damage.

One of the standout features of the 20KVA TRIAC Wall Voltage Stabilizer is its robust protection system. The device includes safeguards against overvoltage (247V±4V), undervoltage (170V±4V), overload, high temperature, and short circuits. This comprehensive protection mechanism ensures that your electronics are shielded from power surges and other electrical anomalies, significantly extending their lifespan.

Additionally, the stabilizer offers a delay time functionality, which includes short delay settings of 3-5 seconds and long delay settings of 3-7 minutes. This delay feature protects your equipment from sudden voltage changes during power restoration, giving you peace of mind during stormy weather or grid instability.

With a power rating of 20,000VA, this stabilizer can handle heavy-duty appliances without breaking a sweat. Its compact design (52 cm x 36.4 cm x 20.3 cm) makes it easy to integrate into your existing setup, while the packaging dimensions (57.5 cm x 42 cm x 28.5 cm) ensure it arrives safely at your location. Weighing in at 39 kg net and 44 kg gross, the 20KVA TRIAC 95-250 Wall Voltage Stabilizer is a solid investment in the reliability of your electrical system.

Whether you’re looking to protect your home electronics or ensure smooth operation in a commercial environment, the 20KVA TRIAC Wall Voltage Stabilizer is a top choice that guarantees high performance and dependable voltage regulation.
