I am trying to understand how TEC modules work, and I think I have it figured out now, but was hoping that someone with more electrical knowledge could verify that I have it right. I am looking at this TEC module. My current understanding of this is as follows: 1. If I regulate the current to this module to a max of 2A, the maximum amount of heat that the module will move at DTmax = 0 would be approximately 75W. 2. If I regulate the current to this module to a max of 2A, the module will not exceed a DT of ~20C. 3. If I regulate the current to this module to a max of 2A, the voltage could range between ~4-6V, but would not reach 10V due to the limitation of DT. 4. Therefore, this module, limited to a max of 2A, would use at max 12W (approximately). Is that all correct? Second, I am comparing the above module to this TEC module. For this second model, my understanding is: 1. If I regulate the voltage to this module to a max of 12V, the maximum amount of heat that the module will move at DTmax = 0 would be 28W. 2. If I regulate the voltage to this module to a max of 12V, the module will reach its DTmax of 67C (theoretically). 3. If I regulate the voltage to this module to a max of 12V, the current could range between ~0.75-1A, but would not reach 2A due to the limitation on voltage. 4. Therefore, this module, limited to a max of 12V, would use at max 12W (approximately). So basically, it is a trade-off between DTmax and heat moved at the same wattage. Is that correct?
