Dimmer, AC 220V 9A 4000W SCR voltage regulator motor fan speed controller

High Quality: Uses a high-performance SCR chip internally. Thickened metal housing, heat-resistant and durable.

Perfect Performance: Stepless voltage adjustment via rotary knob, no hysteresis, no delay, fast response.

The AC voltage regulator cover is equipped with a universal multi-purpose socket and a current indicator. Multiple protection functions effectively protect the high-power thyristors from overvoltage and voltage limits.

Note 1: The 4000W mentioned above refers to the maximum power when operating with a resistive load. The power with an inductive load is 1/3 of the power with a resistive load. The resistive load depends, among other things, on the current of the excitation motor.

Electronic products with printed circuit boards should be used with care.

Note 2: The measured output voltage is an open-circuit voltage. For an accurate measurement of the output voltage, a load of at least 20W must be connected.

The dimmer housing is made of metal and must be properly grounded. Product description: Dimmer, AC 220 V 9 A 4000 W SCR voltage regulator, motor fan speed controller. The output is alternating current, not direct current. This product has a metal housing and must be properly grounded. Stepless voltage adjustment via rotary knob. Thickened metal housing, heat-resistant and durable.

AC 220V 9A 4000W SCR voltage regulator dimmer controller. The power rating under industrial voltage is 1/3 of the resistive voltage. This is the cause of the resistance of the tungsten lamp, the heating wire, and the power source of the motor, the mains exciter, and other components. I produce electronics with an electronic circuit diagram, which should be used with caution. Note 2: The current voltage is set to a virtual voltage when no current is flowing. It must be set to a voltage of 20W or higher to ensure the current voltage is correct.
