Wall-Mounted Automatic Voltage Stabilizer:220V single-phase voltage stabilizer, household fully automatic voltage stabilizer, LCD digital display, 6 large protection chips, high temperature resistance, fast response. One machine has multiple uses, matching a variety of electrical appliances. <1 minute, wiring method: clamp cable, voltage: input: 120-280V, output voltage: 220V±5%. Providing stable AC power for your electric fans, air conditioners, color TVs, refrigerators, computers and other household appliances. Pure Copper Output Wire:The coil is the core component of the voltage stabilizer. We use high-quality pure copper thickened coils, which have longer service life, greater power and higher efficiency. The double-sided large-aperture heat dissipation design is more convenient for ventilation and heat dissipation. Six Major Protection Functions:The voltage stabilizer has overvoltage/undervoltage protection; overcurrent protection; high and low temperature resistance protection; internal overtemperature protection; delay protection and light-ning protection functions, making your electricity use safer. Advantages:The voltage stabilizer has the advantages of small size, high efficiency, no waveform distortion, fast voltage stabilization speed, stable and reliable performance, complete protection functions, beautiful appearance, etc., and can work continuously for a long time.
