General description High-quality AC 220 V dimmer designed for controlling the speed of motors and fans. This voltage regulator features a robust SCR as its internal chip, ensuring reliable performance. The thickened metal shell provides high temperature resistance and durability, making it suitable for various applications. Technical specifications Input Voltage: AC 220 V Maximum Current: 9 A Maximum Power: 4000 W (under resistive loads) Power at inductive load: 1/3 of resistive load Other information Equipped with a universal multi-purpose socket and current indicator Features stepless voltage adjustment with a rotary knob, ensuring no hysteresis or delay and fast response Includes multiple protection mechanisms to safeguard high power thyristors from overvoltage Note: The measured output voltage is virtual without a load; requires a load of 20W or more for accurate measurement The output is housed in a metal casing and must be safely earthed Caution: Electronic products with circuit
