4000W 220V AC SCR Motor Speed Controller Module Voltage Regulator

Product Name: 4000W AC voltage regulator
Size: 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 220V
Adjust the voltage: AC 0-220V
Voltage adjustment range: AC 0-220V, Resistive load conditions, starting a dozen volts, callback can be 0
Note that the load must be connected before it can be regulated
SCR 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 yourself
Fuses 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.
