Pro-Range TEC1-12712 50x50mm Thermoelectric Cooler Peltier Module - 15.8V, 12A, 103W Cooling

The TEC1-12712 requires a stable DC power supply capable of delivering 15.8V at a minimum of 12A continuously, totaling approximately 190W of electrical input. Using an underpowered supply or one without current limiting can damage the module. For optimal performance and to achieve the rated 103W cooling capacity, ensure adequate heatsinking on the hot side.

Integration requires mounting the module between a cold-side surface (to be cooled) and a hot-side heatsink. Apply thermal paste on both ceramic faces to minimize thermal resistance. The hot-side heatsink must be actively cooled (e.g., with a fan or liquid cooler) to dissipate the combined heat load (cooling power + electrical losses). Always secure the module evenly to avoid cracking the ceramic plates.

Yes. A Peltier module's function is reversible. By reversing the polarity of the applied DC voltage, heat is pumped in the opposite direction, turning the 'cold' side into the 'hot' side. This allows the same module to be used for precise heating applications. The same electrical and thermal specifications (15.8V, 12A, 103W heat pumping capacity) apply regardless of direction.

The 65°C ΔTmax is the maximum achievable temperature difference between the hot and cold sides when the hot side is held at a specific temperature (typically 27°C) and no heat load is applied (Qc = 0). In real-world use with an applied heat load, the actual ΔT will be lower. This parameter is key for estimating the module's capability to achieve your target temperature reduction.
