## Overview

The AC 110V-220V 4000W Variable Fan Speed Controller is a robust and versatile device designed for efficient voltage regulation. With an adjustable output voltage range of 10-110V and a maximum power capacity of 4000W, it is perfect for a variety of electrical appliances. Its durable metal construction and advanced safety features make it a reliable choice for both home and professional use.

## Description

NOTE:1.Many motors do NOT support voltage regulation (for example, single-phase motors, dual-value capacitor motors, asynchronous motors, pumps, etc. are NOT supported.) motor-type equipment can only be adjusted: 1): without the capacitor fan2): power tools: hand drill, angle grinder, electric screwdriver, etc.2.The input voltage is 0-110V, then the output voltage is 0-110V.The input voltage is 0-220V, then the output voltage is 0-220V.So both 110v and 220v can be used as the input voltage, But both cannot work at the same time. And it Input alternating current, the output is also alternating current, not direct current.3.This product cannot be connected to DC power, cannot be used as a power supply, and cannot be used with intelligent devices with control boards, otherwise it will cause damage to the circuitTechnical specifications:Input voltage: AC 110V-220VOutput voltage: 10-110V (adjustable)Adjustable voltage range: 0 -110VMax power: 4000WNominal current: 9AMax. Current: 18ADimension: approx 4.53"*3.94" *2.36"Weight:0.88lbPackage contents:1 * voltage regulatorNOTE:1.The measurement of the output voltage in the empty state is a virtual voltage. It must be connected to a load of 100W or more to measure the correct output voltage.2.The above mentioned 4000 W refer to the maximum power when working under ohmic load. The inductive load is 1/3 of the ohmic load. The ohmic load relates to the tungsten light bulb, the heating wire, etc. The inductive load relates to the series exciter motor. There are electronic products for printed circuit boards that are used with caution.3.This product is a metal housing and must be securely earthed.

## Features

- 【Product Parameters】This is a variable speed fan controller, input voltage: ac 110v-220v, output voltage: 10-110v (adjustable), max power: 4000w, max. Current: 18a, dimension: approx 4.53"*3.94"*2.36", weight:0.88lb, adjustable voltage range: 0 -110v.
- 【Powerful Function】Powerful 4000w ac motor speed controller with variable thyristor and electronic voltage regulator. With universal socket and power supply light, and heat dissipation connector for quick heat dissipation.
- 【High Quality】Adopting metal shell structure, high temperature resistance, flame retardant, not easy to rust. Core chip adopts high power thyristor. Which with adjustable button for stepless voltage regulation.
- 【Safety Design】No delay, surge protection, anti-spike, rc absorption multiple protection. Input alternating current, the output is also alternating current, not direct current. This variable speed controller product is a metal housing and must be securely earthed.
- 【Applicable Electrical Appliances】Variable voltage regulator is suitable for electric stoves, water heaters, tungsten filament lamps, small motors, electric soldering irons, fan speed control, etc. Many MOTORS do NOT support voltage regulation (for example, single-phase motors, dual-value capacitor motors, asynchronous motors, pumps, etc. are NOT supported.)
- NOTE: The input voltage is 0-110V, then the output voltage is 0-110V. The input voltage is 0-220V, then the output voltage is 0-220V. So both 110v and 220v can be used as the input voltage, But both cannot work at the same time. NOTE: The above mentioned 4000 W refer to the maximum power when working under ohmic load. The inductive load is 1/3 of the ohmic load. So it can only be used with devices within 100-2000W.
- NOTE: THIS PRODUCT DOES NOT SUPPORT SOME SPECIAL EQUIPMENT and some devices with power around 10 watts, if you can not confirm whether it is suitable for your equipment, you can ask us specific questions to help you get to know it better.

## Questions & Answers

**Q: Does this product have a fuse or other means of self protection?**
A: Hi, thank you for your interest. The switch on the top of the product has the same functional effect as a fuse. When the circuit is faulty or abnormal, it will automatically lose its function to protect the movement. Hoping the answer will be helpful to you.

**Q: I have a wood working lathe what is old and runs of a motor with no controls, would this work?**
A: yes, I believe it will work.  I'm using it to control a 1 hp little giant waterfall pump that runs too fast. This control works.

**Q: Will this regulate a fan speed without causing the fan to hum?**
A: Hello, thank you for your interest.  A large part of the problem you mentioned has to do with the type of fan.  If the speed of the fan is low, there will be resonance, so it will produce sound, but most fans do not have it.  If you need, you can contact us for specific product information.  Hope this helps you.

**Q: The unit shows 220v will this work on 110v?  if so i have a motor on a drill press that is 110v, 10.5 amps, 1720 rpms, 4 pole will your control work?**
A: Hello, thank you for your interest. We are very sorry that the motor you described is a relatively special motor and this product cannot support it. Hope it helps you.
