Pro-Range TEC1-7105 30x30mm Thermoelectric Cooler Module - 8.4V, 5A, 23W Cooling

The module is rated for 8.4V DC and a maximum current (Imax) of 5A, resulting in a maximum electrical input power of approximately 42 Watts. For optimal cooling performance and to prevent damage, it is recommended to use a DC power supply capable of delivering at least 8.4V and 5A with stable voltage regulation.

The module features flat, ceramic faces. For effective operation, one side (the cold side) must be attached to the object you wish to cool using thermal paste or adhesive. The opposite side (the hot side) must be firmly coupled to a heatsink or active cooling system, such as a fan or water block, to dissipate the transferred heat. Proper mechanical clamping is essential to ensure good thermal contact and avoid cracking the ceramic substrate.

Yes. A Peltier module is bidirectional. By reversing the polarity of the applied DC voltage, the sides that were previously hot and cold will swap. This allows the same module to be used for precise heating applications. Always ensure the heatsinking on what becomes the new 'hot' side is adequate to handle the dissipated power.

The ΔTmax of 65°C is the maximum temperature difference the module can achieve between its hot and cold sides under ideal, no-load (Qc=0) conditions when powered at its rated voltage. In real-world applications with a heat load, the actual achievable temperature difference will be lower. This parameter indicates the module's peak thermodynamic performance capability.
