Pro-Range TEC1-12708 40x40mm Thermoelectric Cooler Peltier Module - 15.8V, 8A, 69W

The Pro-Range TEC1-12708 is rated for a nominal 15.8V DC. The maximum operating current is 8A. For optimal performance and longevity, operate within these limits using a DC power supply capable of delivering the required current. Exceeding these ratings can cause permanent damage or reduce cooling efficiency.

Mount the module between a heat sink (on the hot side) and the object to be cooled (on the cold side). Apply a thin layer of thermal paste or a thermally conductive pad on both ceramic faces to minimize thermal resistance. Ensure even, firm pressure across the entire surface to prevent cracking the ceramic substrates. The module itself is not mechanically load-bearing.

The 69W (Q_max) rating indicates the maximum heat energy the module can pump from the cold side to the hot side when the hot-side temperature is held at 27°C and there is zero temperature difference (ΔT=0) across the module. In real applications, the achievable cooling power decreases as the temperature differential (ΔT) between the hot and cold sides increases.

Yes. By reversing the polarity of the applied DC voltage, the heat flux direction is reversed, turning the cold side hot and the hot side cold. This allows the same module to be used for precise heating applications. The same electrical ratings (15.8V, 8A) and thermal limits apply regardless of current direction.

The silicone rubber sealant around the module's perimeter provides a basic barrier against moisture, dust, and minor environmental contaminants. It enhances durability in non-condensing environments. However, it is not a substitute for a full IP-rated enclosure if the module will be exposed to direct water spray, immersion, or corrosive atmospheres.
