heating coil module 12v

Using Arduino General Electronics

25 X 25 is a square, you need another dimension for a box, and that is _______? Will the heater be on the bottom? Side(s)? Is the box top open? I'm thinking of those rubber mat heaters or Kapton strips of around 50 to 75 W and duty cycle switching with a 30 second or so cycle time.
EDIT: I was thinking in inches, make that 20 to 30 W.

Hi,

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

What are you aiming to heat?

Thanks.. Tom... :slight_smile:

Hi,
My heater turned up this morning.
If I get a chance at work over lunch I'll see what it can do.

When you consider that a DC motor's power output is normally controlled via PWM there is absolutely no difference in replacing the motor with a power resistor.

Except that a DC Motor will respond a heck of a lot faster than a power resistor -- so it's not exactly the same :wink:

Depends on what you're measuring :wink: Or what you drive with the motor if we talk speed :wink:
