hardware setup for peltier element and temperature control

[Tresdin]

Hello everyone,

I hope I'm in the right forum for this question. If I'm mistaken it would be nice if a mod could move this to the right forum.

I want to get a Peltier element which I want to set to a certain temperature and keep it at this temperature. The temperature will probably be 30 °C.

As I'm very new to this subject I don't know where to start and what kind of setup I need. I saw that LabView has a PID controller VI implemented.

I guess I would need a programmable power supply and a peltier element. Is this enough to write a program to keep the temperature constant?

Thanks for your help

Best regards,

Tresdin

next toit you need a temperature measurement.

But then it is possible.

I agree with Albert. 

Depending on how fast the temperature can change, a progammable power supply may be too slow to avoid oscillations in the drive to the Peltier device.

Also, some Peltier devices are specified by the current through them rather than the voltage across them, so a current regulator may work better than a voltage regulator.
