AC 220V 6000W SCR Voltage Regulator Motor Speed Controller Dimmer ThermostatFeature:1: Designed with large heat sink for better heat dissipation.2: Convenient to use, simple connection and rotate knob to control voltage.3: The voltage regulator could control light brightness, speed, temperature.4: This is a easy-to use voltage regulator for controlling light brightness or speed.5: Widely used for resistance load such as heating wire, filament lamp and most(not all) single-phase AC motors.Specifics:Condition: 100% Brand NewMax. Power: 6000W (max. power for resistive load. For long time use, please keep it in 3000W)Efficiency: >90%Operating temperature: -40℃~85℃Working Voltage: AC 220VAdjusting Voltage: AC 0~220V (for resistive load, the voltage may not be 0V at first, you can turn it back to 0V)Size: 130*60*47mm / 5.1*2.4*1.9inWeight: 195g / 6.9oz (approx.)Note:1. Please allow 1-3mm difference due to manual measurement.2. The load must be connected before voltage regulation.3. This product is AC input and AC output. It can only be stepped down, and the voltage can be adjusted only when it is connected to a load. It is useless to connect a multimeter with no load, not a transformer.Package Included:1 X Motor Speed Controller
