Pro-Range TEC1-12705 40x40mm Thermoelectric Cooler Peltier Module - 15.8V, 43W Cooling

The module is rated for a maximum voltage of 15.8V DC and draws a corresponding current of 5A under maximum cooling load conditions. Operating at or below these ratings is essential for optimal performance and longevity. Exceeding these parameters can lead to overheating and permanent damage to the thermoelectric elements.

Effective cooling requires mounting the module between two heatsinks using thermal paste on both the hot and cold sides. The hot side heatsink must be significantly larger and actively cooled (e.g., with a fan) to dissipate the combined heat load from the target and the module's own inefficiency. Ensure even pressure to avoid cracking the ceramic substrates.

Yes, by reversing the polarity of the applied DC voltage, the heat flow direction is reversed, turning the module into a heater. The same electrical and thermal ratings apply. For precise temperature control, it is recommended to use it with a PWM controller or a dedicated TEC driver to manage power and prevent thermal cycling stress.

The 65°C ΔTmax is the maximum achievable temperature difference between the cold and hot sides when the hot side is held at a specific temperature (typically 27°C) and no heat load is applied. In real-world use with an applied heat load (Qc), the actual ΔT will be lower. This parameter indicates the module's fundamental pumping capability.
