AC 120V~220V 4000W SCR Motor Speed Controller Volt Regulator Thermostat Dimmer

AC 120V~220V 4000W SCR Motor Speed Controller Volt Regulator Thermostat Dimmer a,a:hover,a:active,a:visited AC 120V~220V 4000W SCR Motor Speed Controller Volt Regulator Thermostat Dimmer Features:A variable-voltage fan speed controller with an AC input of 120–220V and an adjustable output range of 0–220V. It delivers a maximum power of 4000W, with a rated current of 9A and a current limit of 18A.The unit features zero hysteresis and zero delay, along with a peak voltage absorption circuit that effectively protects the high-power thyristor. It provides surge protection, peak suppression, and multiple RC absorption safeguards for enhanced reliability.Its flame-retardant metal housing resists deformation under high temperatures, and the spray-coated metal finish is corrosion-resistant. The voltage regulator is built using an imported high-quality thyristor chip, a high-power semiconductor, an all-aluminum heat sink, and a high-temperature-resistant FR-4 circuit board. Double-sided copper-plated soldering ensures stronger and safer connections.The device uses a multifunctional industrial-grade socket, with thickened phosphor bronze internal copper components for improved durability and conductivity.This transformer-style voltage regulator is suitable for electric stoves, water heaters, tungsten lamps, small motors, electric soldering irons, and fan speed control. However, many motors are not compatible with voltage regulation, including single-phase motors, dual-capacitor motors, asynchronous motors, and pumps.Note:The inductive load is 1/3 of the resistive load. The resistive load refers to tungsten lamps, heating wires, etc., and the inductive load refers to the series excitation motor. etc. Electronic products with circuit boards should be used with caution motor. etc. Electronic products with circuit boards should be used with cautionSpecifications:Type: SCR electronic voltage regulatorInput voltage: AC220VOutput Voltage: 0-220V adjustableLimit Power: 4000WRated Current: 9ALimiting Current: 18AFeatures: Zero hysteresis, zero delay, with peak voltage absorption circuit to effectively protect high-power thyristor, anti-surge, anti-peak, RC absorption multiple protection.
