Effective protection for high-power thyristors: surge protection, peak protection, and RC absorption multiple protections. Product Dimensions: 11.5x6x10cm Product Weight: 0.46kg Points 1. Powerful Functionality: Compatible with 110V power input, maximum current 18A, adjustable output voltage 10-110V/, maximum power 4000W. Resistive load: 2000-2200W, inductive load: 1800-2000W. 2. High-Quality Materials: The casing is made of flame-retardant material, combining high-efficiency flame retardancy with good heat dissipation. Ventilation holes are provided in the body for rapid heat dissipation, extending equipment lifespan. 3. Safe and Reliable: Uses imported chips for precise control and rapid response, featuring zero hysteresis and zero delay. Built-in peak voltage absorption circuit effectively protects thyristors, providing surge protection, peak voltage protection, and RC absorption for multiple protections, ensuring stable equipment operation. 4. Wide range of applications: Suitable for various resistive loads (such as electric cookers, electric heaters, soldering irons, etc.), some power tools (such as electric drills, angle grinders, etc.), and fans with a maximum power of 1500W and a voltage regulation of not less than 170V. 5. Multi-scenario control: Supports stepless speed regulation/voltage adjustment, ideal for bench testing, experiments, industrial applications, and DIY projects, allowing precise control of fan speed and voltage regulation. 6. Precautions: Not suitable for smart home appliances with complex circuit boards. The maximum power limit for inductive loads (fans, routers, soldering irons, small motors) is 1500W, and the maximum power limit for resistive loads (kettles, stoves, tungsten lamps, etc.) is 4000W.
