Review: Ignore the image (red box) buy by part number. Works Great! - This works awesome. I was hesitant to purchase because of the red boxish image. It did not show the actual project. But it was the best price by far that I could find, and had the correct part number, so I took a chance and got it. Glad I did, works perfectly for my Pacific Northwest woodstove insert fan whining issue. Now it is nice and smooth, works well. Review: It worked perfectly. - It was the perfect replacement. Thank you!! ## Features - Fan speed control - For use with permanent split capacitor (psc) and split phase motors - Adjustable min voltage calibration ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0751JW3TQ | | Best Sellers Rank | #263,611 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #287 in Motor Speed Controllers | | Date First Available | August 21, 2017 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.13 ounces | | Item model number | H9042 | | Manufacturer | KB Electronics | | Package Dimensions | 2.91 x 2.17 x 2.05 inches | ## Images ![Model KBMS-13BV (UR) Variable Speed Fan Control, Panel Mount, Rated 3.0 Amps @ 120 VAC for use with Shaded Pole and PSC Motors - Image 1](https://m.media-amazon.com/images/I/61RQPAT2sOL.jpg) ## Questions & Answers **Q: What are outside dimensions of the black housing?** A: The housing is essentially 1.650-inch (length) x 1.650-inch (width) x 1.040-inch (height).
