They are actually a perfect fit and work great!. There is some wiring and drilling necessary to make these work. The job is easy if you know what you are getting into. I removed the resistor from the low speed switch and wired these in with the high speed switch. The knob on these have a click/off position which is perfect. I noted that although during the day you can't see it, at night you can see there is a red LED on the board which glows through the plastic housing of the bunk fan but it is not annoying at all. At low speeds these are perfect, and there is no motor whine. Review: DC motor controller - Ordered these to control 2 small brushless axial fans. Works great. Wide range of adjustment and screw terminals hold tight. ## Features - Ver.2.0 Premium Build: Features original 1803BK dedicated chip and high-grade components, delivering stable performance and extended service life for reliable long-term use. - Precise PWM Speed Control: Operates on 1.8V-15V DC input (recommended ≤12V for optimal safety), with 0%-100% adjustable duty cycle to smoothly adjust small DC motor speed or dim low-voltage LEDs. - Integrated Safety Protection: Built-in 2A self-recovery fuse and power-on LED indicator; the fuse automatically disconnects during overcurrent events and resets after cooling to safeguard your circuit. - Compact & Practical Design: Mini 323214mm size (14g weight) with an integrated on/off switch, ideal for space-constrained DIY projects, small motor drives, and low-power electronic setups. - Clear Usage Guidelines: Supports max 2A continuous current; not compatible with high-current motors (e.g., 775 motors, kids’ ride-on motors) or >0.5A continuous loads; for DC power only—never connect to 110V/220V AC. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N30UK2M | | Best Sellers Rank | #250,373 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #177 in Electrical Motor Controls | | Brand Name | RioRand | | Color | 2A PWM | | Customer Reviews | 4.3 4.3 out of 5 stars (590) | | Display Type | LED | | Global Trade Identification Number | 00701851068507 | | Included Components | 1x Motor Speed Controller | | Item Dimensions L x W x H | 1.26"L x 1.26"W x 0.55"H | | Item Type Name | Low Voltage Dc 1.8v 3v 5v 6v 12v 2a Motor Speed Controller Pwm | | Item Weight | 14 Grams | | Manufacturer | RioRand | | Material Type | Iron, Plastic | | Model | RR-PWM-15V | | Part Number | RR-PWM-15V | | UPC | 701851068507 | | Unit Count | 1.0 Count | | Voltage | 1.8 Volts | | Warranty Description | 3 MONTHS | ## Product Details - **Brand:** RioRand - **Color:** 2A PWM - **Material:** Iron, Plastic - **Product Dimensions:** 1.26"L x 1.26"W x 0.55"H - **Voltage:** 1.8 Volts ## Images ![Temperature, light and speed control - Image 1](https://m.media-amazon.com/images/I/61MQhEYRGKL.jpg) ![Temperature, light and speed control - Image 2](https://m.media-amazon.com/images/I/71LtLhioULL.jpg) ![Temperature, light and speed control - Image 3](https://m.media-amazon.com/images/I/71VbViN1qOL.jpg) ![Temperature, light and speed control - Image 4](https://m.media-amazon.com/images/I/71kwE24hzRL.jpg) ![Temperature, light and speed control - Image 5](https://m.media-amazon.com/images/I/71WDo-xFoeL.jpg) ## Available Options This product comes in different **Set** options. ## Questions & Answers **Q: Is the product here in the us? and not in china. couldn't cancel an order from china. it's going to take 45 days for the product** A: For any product sold on Amazon: The information you need is available right from the product page: Look above the "add to cart" button, and read the estimated arrival date, and most especially, whether the item is "Fulfilled by Amazon", or "sold by and shipped from Amazon". 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for Pop Up trailer bunk fans! *by C***Y on March 22, 2022* I picked these up hoping I could get them to function in the bunk fans for our Pop Up trailer.
