The PC12-139-F1-3550-TA-RT-W6 is a thermoelectric cooler designed for thermal cycling between multiple temperature set points and is ideal for applications in healthcare among others, where fast temperature changes are required. The thermoelectric module is specially constructed to reduce the amount of stress induced on the thermoelectric elements during operation. It has a maximum Qc of 119.2 Watts when ΔT = 0 and a maximum ΔT of 67 °C at Qc = 0 measured at a Th = 27 °C.
