## Overview

The AC Variable Speed Controller is a high-performance device designed for 120V/220V power inputs, capable of handling up to 15A and 4000W under resistive loads. Built with premium materials for durability and safety, it offers adjustable voltage output and is suitable for a variety of appliances, excluding smart devices.

## Description

AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat

## Features

- Powerful Performance: This variable speed motor controller compatible with 120V/220V power input, 15A max current, adjustable output voltage (0-220V), and a 400W limit power. The maximum power is 4000W under resistive load, with inductive load being 1/3 of resistive load
- High-Quality Build: This variable speed motor controller utilizes imported SMD thyristors, all-aluminum heat sinks for high-temperature circuits, and durable FR-4 circuit boards with double-sided copper layer welding. Note: Must be grounded safely due to the metal case
- Safety Assurance: This variable speed motor controller is zero hysteresis, zero delay, peak absorption circuit for protection against surges, spikes, and RC absorption. Equipped with multifunctional industrial sockets and reinforced phosphor bronze fittings for comprehensive security
- Versatile Application: This variable speed motor controller suitable for various appliances like fans, electric stoves, water heaters, small motors, electric irons, and tungsten lamps. Not suitable for smart appliances with circuit boards
- Usage Limitations: Not for use with smart appliances. The fan speed controller maximum power for inductive loads (fans, routers) is about 1500W, and the limit power for resistive loads (electric furnaces, heating wires) is 4000W. Resistive loads include tungsten lamps and heating wires, while inductive loads refer to series-excited motors
