Specifications:Product Name: 4000W AC voltage regulatorSize: length: (L*W*H): 85*55*38mm / 3.3 * 2.2 * 1.5 inches ,knob hole 6mm.Maximum power: 4000W (resistive load limit power), long time should be reduced power use. Long time resistance load recommended within 2000.Efficiency: more than 90%Working voltage: AC 220VAdjust the voltage: AC 0-220VVoltage adjustment range: AC 0-220V, Resistive load conditions, starting a dozen volts, callback can be 0Note that the load must be connected before it can be regulatedSCR is mainly used for resistive load (electric wire incandescent lamp, etc.), single-phase AC motor can also be, but not guaranteed can, other types of load, please confirm by yourselfFuses are not omnipotent, there is reaction time, if the current is too large, in addition to burning the fuse, the module may also burn out.Some Application:Electric furnace, water heater, lamps, small motor, electric iron etc.Attention:Load does not exceed the maximum power, otherwise it will burn module and electrical appliances;use the resistive load as far as possible; reduce inductive and capacitive load power greatly.( it is best to leave more than half of them)Type:Governor/Regulator/Motor speed controller/Dimmer ModulePackage Included:1 x AC 220V 4000W SCR Voltage Regulator Dimmer Motor Speed Controller Module
