AC 220V 4000W/5000W/10000W SCR Voltage Regulator Dimming LED Dimmer Motor Speed Controller Thermostat Dimer 220 V Power Supply

Electrical parameters:

Voltage: AC 220V (180-280V)
Maximum power: 4000W
Voltage Regulator: AC 0-220V
Size: 1.6mm thick high-temperature circuit board long 60x 45x wide high 40mm Knob Diameter 27mm, height 15mm
SCR Current: 41 A
SCR voltage: 800V


Product Name: 5000W AC Voltage Regulator
Dimensions: Length 84.8*Width 70* Height 40mm, without protruding knobs and connectors.
Maximum power: 5000W (resistive load instantaneous limit power), should reduce power usage for a long time, it is recommended to use within resistive load 2200W (key parameters, please pay attention)
Working voltage: AC 220V
Adjust the voltage: AC 0-220V (from high to low can go to 0, from low to high is about 20V)
Note that the load must be connected before the voltage is adjusted.
SCR is mainly used for resistive loads (electric heating incandescent lamps, etc.), most of the single-phase AC



1. Light in the measurement of the output voltage and the input voltage is the same,
needs to be connected to more than 20 w load can measure the output voltage

2. Alternating current (ac), the output is also an alternating current,
it is not a direct current (dc)

3. The above, said 4000 W, is the point at which work load energy impedance,
Inductive load is 1/3 impedance load,
load impedance refers to light, heat wire, etc,
Inductive load is only series motor, etc.

4. The metal housing of electrical equipment,
of safety, please contact with the ground
