Hello everyone,
Quick question. I have three peltier (thermoelectric) elements, two of them rated 6 A, 8.8 V and 33.2 W and one rated 3.4 A, 7.8 V and 16.5 W. Due to the limitations of the components I have available, I need to use all three peltiers (doing otherwise would cause power dissipation problems in the driving circuitry). Now I want to know if there is a possibility of a problem arising from the fact that the three peltiers that I aim to connect in series are not of the same rating? All three peltiers are from the same company, supercool.
I'm using an op amp PID controller to drive the peltiers. The op amp in question is OPA549.
If you guys think there might be a problem, I'll go into details of the circuit I'm using and hopefully this can be sorted out...
