YXQ 4000W Motor Speed Control High Power SCR Electronic Regulator AC 10-220V Adjustable Voltagefor Appliances Dimmer Thermostat

YXQ voltage regulator is a good solution to the over-current problem caused by the small resistance while electric wire core is in cooling.widely used for appliances with power less than 4000W,such as electric furnaces, water heaters, lamps, small motors and more. Working Voltage: AC 220V Regulating Voltage: begin from 10V, AC 10-220V Maximum Power: 4000W (connected resistive load), the power should be reduced for a long time Efficiency: 90% or more Maximum Current: can reach 20A Protection: anti-spike, surge, RC absorption (EOC)， inside 5*20 20A fuse Package include:1Pcs Voltage Regulator Tip: Connect this device with lamp or home appliance or electric circuit,simply connect input terminals to either 220V wire (live wire or neutral wire) and output to load,then rotate the knob for speed, voltage, dimming, temperature control. Note: 1. Must connect the load first and then adjust the voltage. 2. The loaded power can't exceed the specified maximum power, otherwise it will burn the module and electrical appliance. 3. SCR is mainly used for resistive loads (electric heating wire incandescent lamps, etc),and most single-phase AC motors can also be used, but they are not guaranteed.
