Net weight: 70g 2. Size: 74 * 47 * 28（mm） 3. Model: RRCCM2SPC Main technical parameters: 1.Working Voltage: DC 10V - DC 30V 2.Maximum power: 80W 3.Rated Current: 3A 4.Max Current: 4A 5.Short circle time is less than 30 seconds 6.PWM Frequency: 500 KHz 7.PWM pulse width modulation range: 5% -95% What's in box: 1 x RioRand RRCCM2SPC Adjustable DC Motor Speed Controller Review: Perfect for Model Railroading - I bought this to make my own handheld N scale throttle (old school DC) I put it in a very old Radio Shack experiment box. It works perfect and center off switch is really nice when doing slow speed switching Review: easy to install - works perfect, I limit the motor speed of a small 9-watt water pump in order to reduce or regulate the flow rate. ## Features - Maximum power: 80W - PWM Frequency: 500 KHz - Working Voltage: DC 10V - DC 30V - Short circle time is less than 30 seconds - PWM pulse width modulation range: 5% -95% ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00HTZD9YI | | Guaranteed software updates until | unknown | | Item model number | RRPDMSCSGSPC | | Manufacturer | RioRand | | Product Dimensions | 7.4 x 4.7 x 2.8 cm; 60 g | ## Images ![RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - Image 1](https://m.media-amazon.com/images/I/61OKWhkYd2L.jpg) ![RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - Image 2](https://m.media-amazon.com/images/I/71qDn2HqPLL.jpg) ![RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - Image 3](https://m.media-amazon.com/images/I/71J0X7DrtJL.jpg) ![RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - Image 4](https://m.media-amazon.com/images/I/710qsuLSI8L.jpg) ![RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - Image 5](https://m.media-amazon.com/images/I/714WqSoEyqL.jpg) ## Questions & Answers **Q: I connected this to a 4.3 amp Fantastic RV fan to save energy. However now the motor whines at low speed at the PWM freq. How can I stop the noise?** A: You might cure that with a capacitor with a voltage rating higher than the supply voltage, and perhaps a capacity rating of 100 mfd. This capacitor type is polarity rated, so you would need to put it across the terminals going to the fan in way you are supplying the voltage. You would also have to be sure not to reverse the power to make the fan go the other direction. capacitor could probably be as low as 20 mfd. It can be placed anywhere in the line, or right at the fan. The capacitor should smooth out the chopping voltage. As scott says, it might not list to run on low power. **Q: can this contoller switch be used for a razor motor scooter E 300 is 300 watts but if i put a 12 volt battery???** A: No. Your scooter will require a controller that will handle at least 25 amps (the formula is 300 watts, divided by 12 volts, equals 25 amps). This controller is rated at 3 amps continuous and 4 amps peak - at 12 volts that's only 36 watts continuous. **Q: I want to build an electric scooter. Is this a good reverse and speed controler for a DC 12v motor and battery** A: Actually - No, not if it's something you want to ride on. The circuitry in this is simply not heavy duty enough to handle that kind of load or that large a motor. This circuit is intended for something on the order of a toy motor, no more than an amp or two at most. **Q: Can anyone help me find a wiring diagram for this item please.** A: The third picture shows how to connect the power supply and the motor. That should be all you need. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for Model Railroading *by D***D on 17 April 2026* I bought this to make my own handheld N scale throttle (old school DC) I put it in a very old Radio Shack experiment box. It works perfect and center off switch is really nice when doing slow speed switching ### ⭐⭐⭐⭐⭐ easy to install *by P***R on 15 February 2026* works perfect, I limit the motor speed of a small 9-watt water pump in order to reduce or regulate the flow rate. ### ⭐⭐⭐⭐⭐ Worked Perfectly! *by R***. on 18 November 2025* This is quite a bit of electronics for the price. I used this to cut down the speed of a motor I use to drive a small rock polisher. It works perfectly. I really appreciated the graphics on Amazon that show how to wire it up as it did not come with instructions on how to wire it. But, as I said, there is a great picture on the Amazon page that clearly shows how to connect the wires. ## Frequently Bought Together - RioRand Upgraded Adjustable DC Motor Speed PWM Controller 10V 12V 24V 30V Reversing Switch 120W - BRINGSMART 12V 12rpm DC Worm Gear Motor 70kg.cm High Torque Self-Locking Reversed Mini Turbine Geared Motor for DIY Robot Rotating Table Door Lock Curtain Machine (12V 12rpm) - Bringsmart 370 Mounting Bracket with Screw Worm Gear Motor Fixed Fastener DIY Parts DC Motor Holder (Single-Side Bracket) --- ## 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.com.my/products/537912201-riorand-upgraded-adjustable-dc-motor-speed-pwm-controller-10v-12v](https://www.desertcart.com.my/products/537912201-riorand-upgraded-adjustable-dc-motor-speed-pwm-controller-10v-12v) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-09-05*
