Pro-Range TES1-12702 30x30mm Thermoelectric Cooler Peltier Module - 15.8V, 17W Cooling Capacity

The TES1-12702 module is rated for a maximum temperature difference (ΔTmax) of 65°C when operating at its specified 15.8V and 2A under ideal, no-load conditions. The actual ΔT achieved in your system will depend on the heat sink efficiency, ambient temperature, and thermal load.

Power the module using a stable DC power supply capable of delivering 15.8V at a minimum of 2A. For temperature control, you will need an external controller or H-bridge driver circuit to modulate the power. Always use a high-efficiency heat sink on the hot side to prevent overheating and ensure optimal performance.

Yes. A Peltier module is a solid-state heat pump. By reversing the polarity of the applied DC voltage, the direction of heat flow is reversed, turning the cold side hot and the hot side cold. This allows the same module to be used for both precise heating and cooling applications.

Apply even, gentle pressure across the entire ceramic surface during mounting to avoid cracking. Use a thin layer of thermal paste on both sides to minimize thermal resistance. The hot side must be attached to a heat sink capable of dissipating the combined heat load (cooling power + electrical input power) to maintain efficiency and prevent damage.
