It's a Detmar fan that is about 180CFM, 12v 3.5amp motor. I tried to use a small 12v/400ma transformer but the fan burned it out in about 10 minutes. For the 10 minutes it ran it worked great.

So, I purchased a 12v/4a transformer off eBay. When I hook the fan to it all the fan does it pulse on for about a 1/2 sec. every couple of seconds. I test the transformer and it's putting out 12v.

Any ideas on how to hook up this fan without the need of a car battery? These are nice fans and there's a steady supply of them.

Thanks, YGB
I have the exact same fans. Matter of fact I bought two of them.

If they pulse then the adapter you bought is bad. When I tested mine they did the same thing.

Tried a different transformer and it worked great.

You could also use a computer power supply for the 12 vdc
