If your injector is with a DC brush motor and the rated current is below the 60A, HARMNEE pwm motor speed controller will fit for your injector. The rated current is equal to the rate of power divided by voltage 12V. **Q: Why is there a 3 way switch for this?** A: one is for turning off the motor and the other two are for forward and reverse. **Q: Can it be used with arduino to control motor speed and direction?** A: I can't imagine why not as long as the Arduino project meets the volt and amp capacities of the Controller. **Q: Lemon? Two right most terminals wired to 20V battery but the voltage across the two left most terminals always 20V no matter the % of pot adjustment.** A: unplug the pot and connect a meter to center leg and either side legs and check ohms clime as you turn the knob. Make sure all connections are correct. If pot works then controller is bad. ## Frequently Bought Together - PWM DC Motor Speed Controller, DC 10-55V / Rated 40A / Max 60A, LED Display Stepless DC Motor Speed Controller with Adjustable Potentiometer and Forward-Brake-Reverse Switch - Junction Box, Zulkit Project Box IP65 Waterproof Outdoor Box ABS Plastic Electrical Boxes Electronic Enclosure Black 7.9 x 4.7 x 2.95 inch (200 x 120 x 75mm) - Haoguo Steering Triangle Compatible with Newport NK-180S Brushless Kayak Motor, Stainless Steel Structure, Anti-Rust, Easy Installation --- ## 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.co.uk/products/378173956-pwm-dc-motor-speed-controller-dc-10-55v-60a-led](https://www.desertcart.co.uk/products/378173956-pwm-dc-motor-speed-controller-dc-10-55v-60a-led) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-25*
