AC 220V 4000W Variable Voltage Controller Portable Voltage Regulator Temperature Speed Adjustable

FeaturePowerful FunctionPowerful ac motor speed controller with variable thyristor and electronic voltage regulator. With universal socket and power supply light, and heat dissipation connector for quick heat dissipation.High QualityAdopting metal shell structure, high temperature resistance, flame retardant, not easy to rust. Core chip adopts high power thyristor. Which with adjustable button for stepless voltage regulation.Safety DesignNo delay, surge protection, anti-spike, rc absorption multiple protection. Input alternating current, the output is also alternating current, not direct current. This voltage controller product is a metal housing and must be securely earthed.Applicable Electrical AppliancesVariable voltage regulator is suitable for electric stoves, water heaters, tungsten filament lamps, small motors, electric soldering irons, fan speed control, etc. Many MOTORS do NOT support voltage regulation (for example, single-phase motors, dual-value capacitor motors, asynchronous motors, pumps, etc. are NOT supported.)NOTE: The input voltage is 0-110V, then the output voltage is 0-110V. The input voltage is 0-220V, then the output voltage is 0-220V. So both 110v and 220v can be used as the input voltage, But both cannot work at the same time. NOTE: The above mentioned 4000 W refer to the maximum power when working under ohmic load. The inductive load is 1/3 of the ohmic load. So it can only be used with devices within 100-2000W.SpecificationModel: NHT-4000WMaterial: aluminumColor: blackInput voltage: AC110 VOutput voltage: 0-220 VVoltage adjusting range: 0-220 VRated current: 9AMax current: 18APackage list:1 * SCR Voltage Regulator
