I’m having trouble find what I need. I’m looking for an inexpensive temp contoller and heater, must be able to work a 48v dc.
Thanks
What conditions are you going to be operating under? The Routerboards have been quite solid down to well below zero in most people’s experience.
What size enclosure do you have, what devices are in it, what kind of insulation is available, what are expected high & low ambient temperatures, etc.

Depending on things that Russ already asked (what equipment in what box, insulation, …).
One manufacturer that comes to my mind would be lm-therm (located in Germany), see here in English: http://www.lm-therm.de/en/index.php. Look for “Control cabinet heating” there.
They have a broad range of heating solutions, for wide power supply ranges, with integrated thermo controller, …).
