Will these work on controlling heated gear?
« on: December 04, 2019, 06:22:44 PM »
In the dead of winter I use on/off rocker switch for my heated jacked but in the more shoulder months it would be nice to be able to adjust the heat level. It would also ne nioce if they weren't $50 a shot so perusing Amazon I came across these 12V LED dimmers. What say ye think they will work?

  If your heated vest draws less that 6 amps , it may be fine , and at that price what are you waiting for ?

     If it is the heat setting that is important to you, then yes that would probably work. But I also use an on/ off switch with a heated vest, but as a means of compensating for the limited output of my alternator. To me, a set up with that controller would be a continuous draw and would not work for my limited output electrical system. But what do I know?

     I think dimming a "Light Emitting Diode" and varying the voltage to a resistive heat load are two very different things. I would not do it.

Dimming LEDs involves reducing the amount of time the current flows through the diode, as in ON for x milliseconds and OFF for y milliseconds, and repeat. 

The dimmers you listed use PWM, which is Pulse Width Modulation.  I haven't read of anyone using that approach for limiting current through a resistive load like a heater.

A PWM will work great for controlling a heated vest. I use one that I made from parts for a LED controller. The better controllers that you buy from the heated gear companies are PWM.
A PWM will use less amps when you have it set on less than full.

Possibly right church wrong pew. Need to look for somethgin with a higher ampacity. My jacket draws between 6.9 and 7.9 amps.

Having adjustable heat is not of paramount importance but it would be nice a few few days in the fall and spring when it full on is just too much and off with base layers is not enough. Thats why I'm having a hard time spending $50 on a Gerbing controller.

Using a PWM dimmer like that is PERFECT for a resistive heater.

BUT, they are only 6 amp. I'll bet that your vest is near or over that. So I wouldn't use it, just because it is near or over the current capability.

What is the wattage if the vest you want to control?
