It supports a broad voltage range (3-35V) and delivers precise speed regulation with a 1%-100% duty cycle. Featuring a resettable fuse for overcurrent protection and a user-friendly potentiometer for power off, this 24x30mm controller is ideal for professionals seeking reliable, versatile motor and lighting control in a sleek, mini form factor. ## Description Operating Voltage: DC3V-35V Control Power: 90W (maximum) Quiescent Current: 0.015A (standby) PWM Duty Cycle: 1% -100% PWM Frequency: 10khz Size: 24*30mm/0.94*1.18" Package included:10*dc motor controls Review: Works as expected - Units have an off spot that clicks when you turn it from the on to the off position, and it also has a red light that turns on when it's in any position other than off, so it's easy to know that you've switched it off. The design seems to work just fine. I used two of mine so far for a couple of 12v fan control circuits with no issues. Review: These things can really take a beating! - Long story short: After I received these, I thought most of them were defective. But they do require a little bit more than 3 volts. They work so-so with 4.5 volts, and fine wit 6 volts input. I knocked off half a star for the misleading specifications. These were so good, however, that I ordered 2 more six-packs. I dinged the for another half star, because seven of the devices were unfinished from the factory. Six were sans knobs, and the manufacturer (in China) didn't cut seven of them at the cut line on the board, so the board is a little bit wider. And the knobs were left out. I have not tested these unfinished units yet. But with the ones I did test, I accidentally shorted the output, put them in backwards (it's easy to mix up test leads on a cluttered workspace), and thought they were defective. A couple of them started smoking. Then they temporarily quit working. The following day, I tried them again and they all worked! Must be thermal protection on these boards. When I get time, I will test the other twelve from my second order, and give an update if needed. ## Features - 🌟Mini Style DC Motor Speed Regulator controls the speed of a DC motor by adjusting Pulse-Width-Modulated (PWM). - 🌟Mini DC 6-35V 5A PWM Motor Speed Controller. Wide voltage DC motor speed controller, PWM duty cycle: 1% -100%. - 🌟Default disconnection of short circuit point, suitable for 5-35V input. Manually connect the short circuit point according your needs, suitable for low power 3-15v input. - 🌟By screwing the potentiometer, you can turn off power supply output. High voltage and high current resettable fuse, overcurrent automatic disconnection, power off for cooling for a few seconds fuses automatic recovery. - 🌟It is not only to use for dc motor controls of the speed,but also to use for adjust the LED light. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S8JX5SQ | | Best Sellers Rank | #393,245 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #332 in Electrical Motor Controls | | Brand Name | Onyehn | | Customer Reviews | 3.9 3.9 out of 5 stars (135) | | Horsepower | 90 Watts | | Included Components | 6*dc motor controls | | Item Dimensions W x H | 4"W x 0.6"H | | Manufacturer | Onyehn | | Material Type | Copper | | Model | z002 | | Speed | 10 RPM | | Voltage | 24 Volts | ## Product Details - **Brand:** Onyehn - **Horsepower:** 90 Watts - **Product Dimensions:** 4"W x 0.6"H - **Speed:** 10 RPM - **Voltage:** 24 Volts ## Images ![Mini LED Dimmer 5A 90W,DC Motor PWM Speed Controller 3V 6V 12V 24V 35V Speed Control Switch(10 Pack) - Image 1](https://m.media-amazon.com/images/I/613Nmi3GvqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as expected *by I***U on October 4, 2020* Units have an off spot that clicks when you turn it from the on to the off position, and it also has a red light that turns on when it's in any position other than off, so it's easy to know that you've switched it off.

These work great with my 12V applications. They stay cooler than I expected, have a "click" to shut off (when turned fully counter clockwise) and a good degree of accuracy. The control on the knob is smooth. I'm currently using them for 12V fan controls and LED lighting controls and they work great. I'm buying some more. ## Frequently Bought Together - Onyehn Mini LED Dimmer 5A 90W,DC Motor PWM Speed Controller 3V 6V 12V 24V 35V Speed Control Switch(10 Pack) - Evemodel PCB012 Power Distribution Board Self-Adapt Distributor HO N O LED Street Light Hub DC AC Voltage Train Power Control --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/138392784-mini-led-dimmer-5a-90w-dc-motor-pwm-speed-controller](https://www.desertcart.pl/products/138392784-mini-led-dimmer-5a-90w-dc-motor-pwm-speed-controller) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-30*
