My PWM fan controller project, continued....
Hi all,
A few of you may remember I started a simple PWM fan controller project last year. I have an F150, and wanted to control two fans with a simple, affordable PWM controller that would work to minimize current draw while providing safe cooling.
After a while, I sidelined my prototype because of a few issues, and replaced it with a simpler relay system that isn't at all optimal.
I have decided to return to the PWM project, but I have decided to start over from scratch, and put all our heads together to make something great. It'll be an open design anyone can make, but when tested and known to be reliable, I will also make as many as needed and sell them at a low price, enough to cover my costs and time.
The market price for good quality controllers is $250+, with around $350 as the "sweet spot" where most good products are priced. I believe a decent PWM controller can be made and sold, as a complete kit, for under $100.
The savings of PWM fan control, especially on cars and trucks that have a mechanical fan/clutch, can be quite large (I saw a larger gain from using a PWM controller than from using an aerocap)...
So, fishing for interested people to work with, or help test units on their cars/trucks and give me good feedback. Also looking for people who know their PWM circuits, so we can improve the design or replace it altogether.
Who's interested?
