Featuring advanced safety protections, industrial-grade components, and a real-time LED voltage display, it offers precise speed and power control for fans, routers, heating elements, and small motors. Ideal for professionals seeking reliable, adjustable motor control with instant feedback, though caution is advised for inductive loads above 1500W. ## Description desertcart.com : QAGGUM AC Motor Variable Speed Controller for Router Fan Electric Motor Rheostat, SCR Voltage Controller 120V 220V 15A 4000W Max : Tools & Home Improvement Review: Resistive heating control! - Using this to control electric heating mantles for lab glassware, very pleased! So far the biggest load I've hooked up to it is 350 watts but it handled that no problem. There is no hum or coil whine, the box does not get hot, and it gives reasonably fine control over resistive heating elements. As others have mentioned, the range of the dial is a little bit compressed, e.g. my copy doesn't put any power out with my loads until around the 12-13 mark on the dial, but if you add an inline watt meter you can get exactly the right amount of power without any fuss. This is a great value to control simple electronics. Review: Not 4000 watts FIRE DANGER! - Definitely not 4000 watts as I had a 1650 watt item plugged into it. I lost control to the dial after about 10 minutes and then I shut off the power button and it didn’t shut off. It started smoking and it could have caught fire. The cord isn’t even rated for 1200 watts. I definitely would NOT recommend for anything above 1000 watts. ## Features - Specifications: Input voltage: AC 120v-220V Output voltage: 10-110V (adjustable) Maximum power: 4000W Max. Current: 15A, adjustable voltage range: 0 -110V. Note: The maximum power for connecting inductive loads (such as fans and routers) is about 1500W, and the maximum power for connecting resistive loads (such as electric furnaces and heating wires) is 4000W - Safe and Reliable: Fan speed controller has no lag, no delay, surge protection, anti-peak, and arc absorption multiple protections. Input and output are all AC. The core chip adopts a new bi-directional high-power thyristor with adjustable buttons and a current of up to 15A, which solves the problem of wire overcurrent when the heat dissipation resistance is too large and provides you with comprehensive safety protection - High Quality and Durable: Variable fan speed controller uses imported high-quality chip thyristors and electronic voltage regulators, heat dissipation plugs, and all-aluminum heat sinks, which are suitable for high-temperature circuits and provide rapid heat dissipation. Using multi-functional industrial sockets and thickened phosphor bronze accessories, high stability, using high current, good contact - Wide Range of Applications: Variable voltage regulator widely used in electric stoves, water heaters, tungsten lamps, small motors, fan speed regulation, electric soldering irons, etc. Many motors do not support voltage regulation (for example, single-phase motors, dual-value capacitor motors, asynchronous motors, etc. are not supported.) Warning, not suitable for smart home appliances with complex circuit boards - Super Convenient: The LED power indicator light allows you to know the working status at any time, and the display screen displays the output voltage in real time, making the working voltage clear at a glance, making it easy for you to adjust at any time, making your work more convenient ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CR5C29XH | | Best Sellers Rank | #393,799 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #323 in Electrical Motor Controls | | Brand Name | QAGGUM | | Color | Black | | Customer Reviews | 3.6 3.6 out of 5 stars (14) | | Display Type | LED | | Included Components | 1*Variable Speed Controller | | Item Weight | 0.52 Kilograms | | Manufacturer | Naviclass | | Material Type | tungsten | ## Product Details - **Brand:** QAGGUM - **Color:** Black - **Display Type:** LED - **Item Weight:** 0.52 Kilograms - **Material:** tungsten ## Images ![AC Motor Variable Speed Controller for Router Fan Electric Motor Rheostat, SCR Voltage Controller 120V 220V 15A 4000W Max - Image 1](https://m.media-amazon.com/images/I/61PkxmuLMPL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Resistive heating control! *by A***M on February 27, 2026* Using this to control electric heating mantles for lab glassware, very pleased!

I used a power strip in the box and plugged the fans in power strip. ## Frequently Bought Together - QAGGUM Variable Speed Controller for Router Fan Electric Motor, SCR Voltage Controller 120V 220V 15A 4000W Max - 110V 250W US Style Electric Blacksmith Forge Blower Blacksmithing Coal Forge Fan air Blower Tools with 125CFM --- ## 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.pl/products/611377591-ac-motor-variable-speed-controller-for-router-fan-electric-motor](https://www.desertcart.pl/products/611377591-ac-motor-variable-speed-controller-for-router-fan-electric-motor) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-26*
