220V AC Voltage Regulator, 220V 4000W Voltage Dimmer, Fan Motor Voltage Regulator, Speed Controller, EU Plug

【Metal shell】 The voltage regulator's casing is made of thickened metal, resistant to high temperatures, flame retardant, and rustproof; the product design is compact and lightweight, with heat dissipation on five sides, no heat buildup, no deformation, safe and durable.【High performance】The voltage regulator uses a high-performance thyristor as its internal chip. It achieves continuous voltage regulation via a button, with zero lag, zero offset, and fast response.【Multiple protections】Effectively protect high-power thyristors against overvoltage, surge, and multiple RC absorption protections.【Wide range of uses】 This product is equipped with a universal plug and a power indicator, as well as a continuously adjustable voltage regulator, which is used to reduce the power consumption of ovens, water heaters, low-speed motors, and electric irons.【Remarks】The output is alternating current, not direct current. This product has a metal casing and must be firmly grounded. The measured output voltage is a virtual open-circuit voltage. It must be connected to a load of 20 W or more to measure the correct output voltage.
