Light dimmer, SCR AC 220V 9A 4000W voltage regulator for motor, fan, speed control

High quality: Uses a high-performance SCR as the internal chip. Thickened metal casing, resistant to high temperatures and durable in use. Perfect performance: Stepless voltage adjustment with rotary knob, zero hysteresis, zero delay, fast response. The AC voltage regulator cover is equipped with a universal multipurpose socket and a current display. Effectively protects high-performance thyristors against overvoltage and voltage limits with multiple protections. Note 1: The 4000W mentioned above refers to the maximum power when operating under resistive loads. The power under an inductive load is 1/3 of the resistive load. The resistive load relates to the current on the line excitation motor and more. Electronic products with printed circuit boards should be handled with care. Note 2: The measured output voltage is a virtual voltage if there is no load. It must be connected to a 20W or higher load to measure the correct output voltage. The output is a metal casing and must be safely grounded. Product Description: Dimmer, AC 220V 9A 4000W SCR Voltage Regulator Motor Fan Speed Controller. The output is AC, not DC. This product has a metal shell and must be safely grounded. Enjoy continuous voltage adjustment via a knob. Thickened metal casing, resistant to high temperatures and durable in use. High quality, adopting a high-performance SCR chip as the internal component. Thick metal casing, resistant to high temperatures and durable in use. Perfect performance: continuous voltage regulation with a knob, zero hysteresis, zero delay, fast response. Quick response The AC voltage regulator has a universal multi-use pressure and a current display Multiple protection Effectively protects you with high voltage protection and RC absorption with multiple protection. AC 220V 9A 4000W Voltage Regulator SCR Dimmer Regulator The power is at 1/3 of the ohm level. It is the cause of the resistance to the tungsten lamp, the heating wire and the source of the motor of the line exciter and the other ancora. I produce electronics with an electronic schedule which must be used with a cautela. Note 2: the current voltage is set to a virtual voltage when it is not high, must be set to a voltage of 20 W or higher to ensure the current voltage is correct.
