Tec controller

I recently picked up a couple of these kits QKits Electronic Kits: FK934, Thermostat Kit 0 - 100 C to try and control a few TEC's. One kit will be used to control a TEC that will be cooling two blu-ray diodes combined with PBS for a scanner. The other kit will be used to control the TEC in a TO-3 635nm diode.

One problem I found is the output is AC and I want to control a DC output. Here is where I found the suggestion to get this kit http://www.photonlexicon.com/forums/...troller&page=2 post #30.

Another problem I found is this kit uses an IC to detect temperature and I want to use a themsistor inside of a TO-3 diode to control the TEC. I might be able to replace one of the 10k pot's that is used to set the on/off TEMP with the 10K thermsistor inside the TO-3. If anyone has any suggestions to help use this kit for my application that would be great.

MISTERWILLING;

I have loads of 10K thermistors that I can offer you.

The circuit output in the picture is a 10 Amp relay. If so then it can also handle DC voltage at a lower current.

I have a couple of lenses installed in your brass housings.

(as long as you focus them correctly)

I might need one of those Themisitors if I can run DC through the relay. I also have a few lasers that I need the power checked on. One is a TO-3 diode that I'm still waiting on a housing for it before I can keep it running for a long period of time. I will stay in touch.
