About this item

  • Electrical Specifications of voltage regulator - Input voltage range of 110-120V, with a maximum current 15A and a rated current of 9A. Supports a maximum resistive load of 4000W and an inductive load of 1500W.
  • Robust Protection of Electric Motor - This variable speed controller features multiple safety measures including surge and spike protection, along with RC absorption. Its flame-retardant casing withstands high temperatures and offers excellent resistance to conductivity, rust, and high voltage, ensuring top-notch safety.
  • Overload Protection with VFD Fan Speed Control Switch - The PWM fan controller includes a dedicated voltage control switch with overload and short-circuit protection. It automatically shuts off when the current exceeds 15 amps, safeguarding both the equipment and users.
  • Portable Design of Motor Controller - This small electric motor is designed for convenience, it easily clips onto belts for operation. Compatible with standard Type A and Type B plugs in the U.S., it also has a high-precision LED voltage display for real-time adjustments.
  • Wide Compatibility - This power a controller can adjust temperature, speed, light, and voltage settings, making it suitable for electric fans, exhaust fans, drills, angle grinders, blowers, and LED lights. However, it is not intended for use with appliances that have circuit boards or capacitor components, such as microwaves, induction cookers, rice cookers, water pumps, washing machines, and energy-saving LED lamps.

Usage Guidelines

  1. Check voltage correctly: Measure output voltage under load (minimum 20W). Empty-machine readings show ghost voltage.
  2. Stay within specs: Operate only within rated power/voltage ranges. Designed for standard AC power sources.
  3. Power limits: Resistive loads: Max 4000W Inductive loads (e.g., motors): Limit to 1/3 resistive capacity Use extreme caution with circuit board electronics
  4. Normal operation: Moderate heat during use is expected. Keep in dry, ventilated areas.
  5. Safety first: Flame-retardant casing requires proper grounding. Always use grounded outlets.
  6. Incompatibility: Avoid soft/slow-start voltage regulators. Not supported.

(Key improvements: Concise phrasing, bullet hierarchy, technical terms like "ghost voltage," active voice, and removal of redundant explanations while preserving critical safety info.)
