High Performance: Engineered for robust functionality, this speed controller handles up to 4000W power. It supports 2000W for resistive loads, 500W for inductive loads, and 300W for capacitive loads. Exceeding these limits may damage the device. Construction: The controller's casing is crafted from flame-retardant, thickened plastic, offering superior resistance to high temperatures, flames, rust, and high pressure, ensuring long-lasting durability and safety. Optimized Voltage Regulation: This device offers continuous voltage adjustment with zero hysteresis and delay, ensuring a rapid response. Note: It is not suitable for pumps and motors that require capacitors or lack carbon brushes. Enhanced Safety Features: Equipped with a multi-purpose socket and power indicator, this voltage regulator includes overload protection to shield against surges and voltage spikes, safeguarding the high-performance thyristor and RC absorption. Versatile Use: Ideal for a wide range of applications, this regulator can adjust light, speed, voltage, and temperature. It's perfect for heating pipes, electric stoves, lamps, small motors, soldering irons, and electric drills.
