Heated jacket variable resistor?
 

Hi I have made my heat4jackets kit, nice kit easy to do. However I find it too hot so I would like to add some sort of variable resister into the circuit (I will proable mount it on/in the fairing) to drop the voltage, and hence control the heat output. I have seen the ones gerbin etc use and understand they are better(using less power by ossilating on and off), however they cost a bomb compired to a variable resistor.
However can some one whith more electrial knolage than me point me in the direction to go, I understand it needs to be 12V about 55W and the kit has a 20amp fuse So I need some thing that can take these powers. Has somebody done this before? The ones I have seen on ebay/google look perfect but I don't know if they can take the power the jacket draws.

Thanks alot George

I don't know about the cost difference but you could look at
Warm & Safe. Warm & Safe Heated Clothing and the Heat-troller for the Real Thing!
I have heard that they use the "Heat Troller" that Gerbing used at one time.

George, let me know what you come up with. I am also interested in a low cost trimpot solution for Gerbings heated clothing (gloves and socks).

John, unfortunately the Warm & Safe controllers are priced the same as the Gerbings ones. At USD100 for a dual controller, I think it's too high.

I have a used 12 volt controller which will work up to 4 amps for £15. Low draw, polarity & thermal protected. Some of the gerbings equipent is high amp so check first. My one does have a thermal cut out so you wont damage it.
WarmandSafe started out making controllers only for high amps, but said they were ripped off with a cheap copy. You don't want the cheap copy which may be sold by a well know branded company.
PM me and we can exchange emails.
