ALSO, underneath the bulletted description next to a product's photo, look for a link that says some number is "New from", or "News and Used from"; if you click it, a side menu slides out that shows sellers, prices, whether shipping is free or not, and the estimated delivery date. **Q: Is this the best thing to dim some led lights ? Is it bad to use? I know it should work but...?** A: I used 3 of these to control each color of a strip of SMD 5050 LEDs. They work great. No buzzing, smooth linear control. **Q: what is the PWM frequency?** A: Frequency can be changed with C2. 0.12nF 66.7KHz 1nF 11.4KHz 10nF 1.2KHz 100nF 118Hz 1000nF 1.2Hz **Q: Does the knob include an on/off function or does it just adjust the speed? Need to know if I need to purchase an additional power switch.** A: The knob has an on/off function. ## Frequently Bought Together - RioRand RR-PWM-15V Low Voltage Dc 1.8v 3v 5v 6v 12v Motor Speed Controller, 2A PWM - RioRand 6V 12V 24V 28V 3A 80W DC Motor Speed Controller PWM Speed Adjustable Reversible Switch 1203BB DC Motor Driver Reversing - Greartisan DC 12V 550RPM Gear Motor High Torque Electric Micro Speed Reduction Geared Motor Centric Output Shaft 37mm Diameter Gearbox --- ## 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.za/products/9338040-ver-2-0-premium-pwm-dc-motor-speed-controller-1803bk](https://www.desertcart.co.za/products/9338040-ver-2-0-premium-pwm-dc-motor-speed-controller-1803bk) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-12*
