Volt Regulator 4000W AC Regulator 220V SCR Motor Speed Controller Module Voltage Regulator Dimmer Electronic Voltage Regulator Features: * new and high quality. *High Power Control: This 4000W electronic voltage regulator offers high power control for a range of electrical appliances, including speed, temperature, and light adjustments. *Surge Protection: Equipped with a dual capacitor design (safety capacitor + metal film capacitor), this SCR Voltage regulator effectively absorbs surges and voltage spikes, protecting the controllable silicon and increasing efficiency. *The circuit has undergone many technical improvements, and each accessory is now fully technologically mature. *Thyristor is mainly used for resistive loads (electric heating wire incandescent lamps, etc.), and most of the single-phase AC motors can also be used, but they are not guaranteed. Specifications: Product name: 4000W AC regulator Size: 85*55*38mm Knob hole: 6mm High power: 4000W(resistive load power limit), long time should reduce the power use. Efficiency: more than 90% Working voltage: AC 220V Regulating voltage: AC 10-220V Package Included: 1 x Volt Regulator Note: 1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2. Please allow slight manual measurement deviation for the data. _x000D_ _x000D_
