Does anyone know a good TEC controller ?

Hi Guys

I am on the look for a good full bridge PWM TEC controller, capable of at least 10A current.. (with adjustable setpoint, current, etc.)

I have been looking at one from supercool which has both rs232 port and a lot of stuff that i dont need, but is that really the only one out there.. It seems to me that this is not rocket science, so i dont understand why i cant find a relatively low priced simple product...

Does anyone know where to find something usefull, or do i really have to design it myself ?


Thanks !

Regards, Simon

I know of the Die4Chill, but can't find any mention of it at the above URL.

just e-mail robin

The following link is to a post Robin posted on his Die4Chill unit

I'm afraid the die4chill is not full bridge!

you can find some here : http://www.teamwavelength.com/produc...urecontrollers

Hello
Yes, i know the wavelength controllers and have used them a lot.. however for this application i need a lot of current for the tecs, so these controllers being linear, will dissapate a lot of heat, so i would prefer if i could find something pwm..

At this moment a device from oven industries (www.ovenind.com) seems to be the best solution, allthough it is just as expensive as the one from supercool..

Thanks !

If you can lay out a circuit pcb, check out the PIDC120 controller IC.

Take a look there:

Try www.accuthermo.com, they are partner company with Ferrotec.com who is the TEC manufacture.
They have many controller and h-bridge amplifier selections.

Sorry, my first time post here, I did the repost and don't know how to delete it.

Try www.accuthermo.com, many selection from low to high (high like ~30V ~30A, 700W)

Talk to badpip or andythemechanic. I have 12v/7A controllers in stock. Size is 35x35mm

solarfire had a TEC driver around in another thread, but dave had die4drive tec's in stock, but edison is closer.

Maybe these are suitable :

this is cheap and can work good i think!

I have been playing round with around with a little tec driver that is essentially a die4chill, but instead of bang bang operation, this ones PI.. What are peoples thoughts on max current? Currently its just a die4chill with some mods to the pwm circuit, but I could beef up the output?

TEC (Thermo Electric Cooler, or Peltier Cooler) is a semiconductor device which can cool down or heat up the temperature of an object depending on the direction of the current going through the TEC. By using our TEC controller, the object's temperature can be regulated precisely by controlling the direction and magnitude of the current going through the TEC.
more information,please see：www.analogtechnologies.com

I have used a great TEC Controller, the effect is very good, high stability and high reliability. This firm: www.analogtechnologies.com

Release the hounds !!!!!!!!!

Yeah... the last 2 posts by the NOOBs with 1 post to their name seem
to be spamming this +3 year old Thread. Woof... Woof...

Massive grave-dig too... sigh.

To stay on-topic, I just ordered a bunch of cheap PID controllers from Banggood.cn. They appear to be similar to the units that CDBeam was using a while back, but instead of costing $40-$50 each, they were less than $15 each. We will see how well they work...

Adam

so, are the bangood controllers any good?

To be honest, I haven't hooked one up yet. :o

But they appear to be fine. Also, they've added quite a few new models since I ordered mine. Now they even sell kits complete with a solid state output relay and a temperature sensor.

Adam

I have used a few of these: http://www.oteinternational.com/temp...ntrollers.html

The model TEC 45 and TEC 65 are now TEC-ALL and have a wider adjustment range. They have a PWM output, work very good and are reasonably priced. They were selling on ebay but I cant find them now.
