This voltage regulator is designed for motor speed regulation, allowing precise output voltage adjustments via a multi-ring potentiometer.It offers continuous AC voltage adjustment from 0V to 220V with zero lag and delay, ensuring ultra-high heat dissipation.Equipped with anti-surge and anti-peak protection, along with RC absorption for enhanced safety.The device can be connected in series with lamps or home appliances, enabling control over dimming, speed, voltage, and temperature by simply rotating the knob.It features a two-way large power silicon controlled rectifier, capable of handling currents up to 100A.This voltage regulator is ideal for various applications, providing flexibility in controlling electrical devices. With a maximum power capacity of 8000W for instantaneous loads and a recommended continuous use of 4000W or lower, it ensures reliable performance. Users should connect the regulator in series with the load and have some professional knowledge for safe operation. Please note that voltage adjustment should not be attempted before connecting the load.Color: As ShownMaterial: PC+MetalPackage Contents:1*8000W Electronic Voltage RegulatorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
