4000 W Voltage Regulator — Motor and Dimming Control Why you need it Single device for high-power control: provides reliable control of voltage, motor speed, dimming and temperature for many household appliances up to 4000 W. Easy to install and use: built-in control circuitry and a potentiometer with locking nuts mean no extra components are required for basic operation. Versatile and practical: designed for motor control and dimming applications where smooth, adjustable power control is needed. Key features Power rating: 4000 W capacity for high-power household appliances and small motors. Control method: high-performance silicon control for stable dimming and motor regulation. Built-in potentiometer: adjustable dial with nuts for secure mounting; allows direct, straightforward adjustment without additional parts. Multiple functions: supports dimming, speed control, voltage regulation, and temperature control depending on the connected appliance. Practical design: intended for straightforward inline connection to the appliance; turn the control knob to adjust output. Compatible devices Electric oven Water heater Lamps and lighting fixtures Small motors (fans, pumps, etc.) Electric iron Other household appliances that accept variable voltage control and fall within the 4000 W rating How to use Connect the regulator inline between your power source and the appliance. Secure the potentiometer using the supplied nuts. Turn the control knob to vary output for dimming lamps, adjusting motor speed, or changing heater temperature. Designed to work without extra external components for standard control tasks. Practical use scenarios 1) Lamp dimming: Install between mains and a compatible lamp to smoothly reduce light output with the knob, useful for task or ambient lighting control. 2) Motor speed control: Use with a small motor (fan or pump) to adjust speed for quiet operation or flow rate changes. 3) Temperature adjustment: Install with a heating appliance (iron, small water heater) to fine-tune temperature within the limits of the appliance and the regulator’s 4000 W rating. What makes it stand out High 4000 W capacity lets you use the same regulator for larger household appliances and motors. High-performance silicon control ensures consistent regulation across the adjustment range. Potentiometer with nuts provides a secure, no-fuss mounting and simple user control. Ready to use without additional components for common dimming and motor-control tasks. Safety and compatibility notes Confirm the appliance power draw does not exceed 4000 W. Ensure the appliance is compatible with variable voltage control before use. Follow local electrical codes and, if unsure, consult a qualified electrician for installation.
