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 ## Product Details - **Color:** Black - **Brand:** Generic - **Voltage:** 2.2E+2 Volts (AC) - **Product Dimensions:** 4.49"L x 3.94"W x 3.15"H - **Material:** Plastic, Metal ## Images ![AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Image 1](https://m.media-amazon.com/images/I/61JX3LMywpL.jpg) ![AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Image 2](https://m.media-amazon.com/images/I/71zrS2ZKKXL.jpg) ![AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Image 3](https://m.media-amazon.com/images/I/61L8GeQPMpL.jpg) ![AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Image 4](https://m.media-amazon.com/images/I/814pDStKb1L.jpg) ![AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Image 5](https://m.media-amazon.com/images/I/71hlN9qiRNL.jpg) ## Frequently Bought Together - AC Variable Speed Controller, 120V~220V 15A 4000W, Variable Speed Controller & Fan Speed Controller with Rheostat,Variable Voltage Regulator Router for Electric Motors Rheostat - Hosyond 3.5 Inches TFT LCD Touch Screen Shield Display Module 480x320 SPI Serial ILI9488 with Touch Pen Compatible with Arduino R3/Mega2560 Development Board --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/611440088-ac-variable-speed-controller-120v-220v-15a-4000w-variable-speed](https://www.desertcart.pt/products/611440088-ac-variable-speed-controller-120v-220v-15a-4000w-variable-speed) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-27*
