Pro-Range TEC1-7102 30x30mm Thermoelectric Cooler Peltier Module - 8.4V, 2A, 9.3W

The TEC1-7102 is rated for 8.4V DC operation with a maximum current draw of 2A to achieve its specified 9.3W cooling capacity. It is crucial to use a DC power supply or driver capable of delivering this current steadily; under-driving or over-driving the module will affect performance and temperature differential.

For optimal performance, the hot side of the module must be attached to an adequate heatsink (often with a fan) using thermal paste to minimize thermal resistance. The cold side should be in direct thermal contact with the object or surface to be cooled. Ensure even pressure and electrical isolation as needed. Without proper heatsinking, the module will not achieve its rated ΔT and may overheat.

Yes, the Peltier effect is reversible. By simply inverting the polarity of the applied DC voltage, the sides that previously absorbed and dissipated heat will swap. This allows the same TEC1-7102 module to be used for precise heating applications, making it ideal for temperature cycling or dual-mode thermal control systems.

Under ideal conditions with perfect heatsinking on the hot side and no load on the cold side, the TEC1-7102 can achieve a maximum temperature difference (ΔTmax) of up to 65°C between its two ceramic faces. In practical applications with an active heat load on the cold side, the achievable ΔT will be lower and depends on the cooling power required.
