Usage Tips: Advanced Power Capacity: This speed controller delivers a power output of 4000W. Suitable for resistive loads up to 2000W, inductive loads up to 500W, and capacitive loads up to 300W. Exceeding these limits may damage the device. Versatile Specifications: Features an EU plug with input voltage AC 220V and adjustable output voltage from AC 0–220V. Rated current: 10A; maximum current: 18A. Compatible with 50 Hz / 60 Hz frequency. Enhanced Performance: Provides continuous voltage adjustment for precise control. Includes a voltage absorption circuit for protection against overload and voltage spikes, enabling immediate response without delay or hysteresis. Robust Protection Measures: Equipped with a multi-purpose socket, power indicator, and thyristor protection. Offers protection against power surges, voltage spikes, and overcurrent via RC absorption and overload protection.
