i want to be able to control the cooling temperature of a small 40 to 60millimter TEC. I understand voltage level plays a part but do not know what voltage level equtes to what temperature on either side of the TEC. Is there a way to ascertain this? Or is there a standard time frame the for the TEC to get to to a required temp using X amount of voltage?
Or am i better to monitor the temp another way and then turn off or hold voltage when the required temp is reached. I am looking to get to temperatures between 6 and 14 degrees centigrade. I need a simple, reproducible and cheap way to do this. Thanks
