3KVA Industrial AVR Stabilizer | 220V/110V ±3% | CE/ISO Certified

Factory Price 3KVA OEM Automatic Voltage Stabilizer, Servo Motor Control Single-Phase AVR 220V/110V

If you are searching for a reliable servo motor automatic voltage stabilizer, this TND(SVC) series 3KVA single-phase AVR automatic voltage regulator delivers stable AC output for homes, offices and small-scale industrial sites suffering from grid voltage fluctuation. As a factory-direct AC voltage stabilizer supporting OEM customization, it stabilizes unstable mains voltage and protects sensitive electrical appliances from voltage surges, over-voltage and under-voltage damage, extending service life of your expensive equipment.

Built around contact-type auto-transformer, high-performance servo motor and integrated sampling control circuit, this single-phase servo voltage stabilizer detects input voltage changes in real-time and drives carbon brushes to adjust transformer output automatically, holding output voltage at rated value without extra waveform distortion. The output supports 220V or 110V, fits global 50Hz /60Hz power grids, voltage accuracy reaches ±3% for 220V output and ±6% for 110V output, efficiency ≥90%, response time ≤1 second under 10% input voltage shift, meeting strict power-quality demands for precision loads. Core components adopt tightly-wound pure purple-copper coils and durable 1017 carbon brushes with up to 8-year service life, improving heat conduction and lowering failure rate for long-term continuous running. Equipped with digital LCD display, users can check real-time input and output voltage conveniently.

Multi-layer safety protection makes this home and industrial AVR stabilizer stand out from ordinary voltage regulators. It integrates overload protection (trigger output cut-off under 120% load), over-voltage & under-voltage cut-off, short-circuit protection and power-on delay protection. When short-circuit fault occurs, the stabilizer will shut output down automatically and require manual reset, effectively avoiding burn-out caused by bad power conditions in areas with poor grid quality. Multiple heat-dissipation holes on metal cabinet realize efficient cooling for non-stop operation; low-noise running performance makes it suitable for office, lab and residential environments. Besides standard 3KVA model, we supply full capacity range from 5KVA,10KVA up to 60KVA single-phase voltage stabilizer for selection.

This high-precision automatic AC voltage stabilizer covers broad application scenarios. It works perfectly as voltage stabilizer for household appliances including air-conditioners, refrigerators, televisions and audio devices. For commercial and light-industrial usage, it protects embroidery machines, microcomputers, small electromechanical devices and laboratory instruments. It is also widely adopted in telecommunication equipment, medical auxiliary apparatus, agricultural machinery and construction-site electric tools where unstable grid power often causes unexpected equipment shutdown or hardware burnout. If you run projects in regions with severe voltage drop or voltage spike, this servo-type AVR voltage regulator will be your cost-effective power-protection solution.
