## Description

DC Motor Speed Controller Universal DC 12V 24V 10A Electronic Stepless Speed Regulator Switch for Car Truck Fan Heater Control, 1-Pack: desertcart.com: Industrial & Scientific

Review: Works well on bench test - I have this wired up to an Inferno slim line UTV/Auto heater core blower. It is an axial 5 amp max blower fan (SPAL VA31-A101-46s to be exact). The instructions in the listing are not correct for how to wire it up. Only one picture in the listing has the correct information. Battery + power gets connected to both the switch red and + to motor Battery - gets connected to switch black wire Motor - gets connected to switch Blue wire I connected this up and ran it at multiple fan speeds for multiple hours. Switch did not overheat or have any issues. Neither did the fan operation. Hopefully it lasts. So far works exactly as I needed it to. I will post update if it prematurely fails.
Review: Camper fan repair - Works great for my camper bathroom fan. The circuit board went bad and would only work on speed 1. New circuit board was over $100. Removed circuit board and added this variable switch and 2 way taped it to the shroud. Only directions are on the desertcart add and they are not great. This worked for me. Black wire to negitive/ ground Blue wire to negitive/ ground on motor or whatever device you are hooking up to. Red wire to positive input and positive on fan or device you are hooking up to.

## Questions & Answers

**Q: does unused current/power of the device get dissipated through the heat sink? if my device consumes 40watts will it use all 40watts even if on low?**
A: I don't believe it gets dissipated. It has a squeal to it at some speeds which tells me its a PWM so its turning the device on and off really fast, not acting as a resistor like old school speed controllers.

**Q: Had anyone used it to add intermittent wiper capability to a truck w/o intermittent wipers?**
A: This is not the component to use for that function, this would just make the wipers move more slowly, they sell kits to add intermittent wiper functions, to older cars and trucks such as

**Q: Voltage range with 12v input? About 0 - 12v? 4 -12v?**
A: It worked for maybe 10 minutes

**Q: Can this be used to dim a halogen bulb?**
A: yes, only if the bulb is a dimmer bulb.

### ⭐ Worked great until it died after 5 min. of use.
*by C***M on July 5, 2022*

I should have read more of the reviews before purchasing. The thing was pretty straight forward to install. It ran great controlling a 12v 80w transmission cooler fan for about 5 min. and then died. the housing was super hot. The fins weren't hot at all. I pulled the cover unit and tapped a few of the components and the thing would work sporadically until it stopped working altogether. Buyer beware.
