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 Upgraded Construction：Adopts genuine 1803BK dedicated chip and high-grade electronic components. Solid craftmanship ensures steady output performance and longer service life than standard ordinary versions. - Adjustable PWM Speed Regulation：Supports 1.8V-12V DC input with max 15V tolerance, features 0%-100% duty cycle adjustment. It works for tuning small DC motor running speed and low voltage LED brightness. - Built-in Overcurrent Protection：Comes with integrated 2A self-recovery fuse and power indicator light. The fuse cuts off circuit under overcurrent and recovers automatically for circuit protection. - Mini Integrated Structure：Measured 32×32×14mm and 14g in weight, equipped with independent on/off switch. It fits neatly into small space for daily DIY electronic and hobby project assembly. - Clear Application Specification：Rated for 2A continuous current input.

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.
