What this module is and who it is for

The Unique-Bargains TES1-7102 is a thermoelectric cooler plate that moves heat when DC power is applied. It suits experimenters, hobbyists or engineers building custom cooling or temperature-control projects. The 23 by 23 by 4.5 millimetre white ceramic plate ships with a 30 centimetre lead attached. It is not for buyers who need a ready-to-mount assembly with heatsink or fan included.

Thermals noise and power draw

At the rated 8 volts and 2 amps the module draws 10 watts and can create a temperature difference of about 65 degrees Celsius (149 degrees Fahrenheit) between its two faces. The supplier measured roughly 65 °C delta at 5.78 volts input. Without a heatsink on the hot side the device will overheat and fail in seconds, so active cooling is mandatory. There are no moving parts, so the module itself makes no noise.

The specification that decides fit

The critical figure is the 10 watt, 8 volt, 2 amp operating point that sets both the heat-pumping capacity and the power-supply requirement. Match your thermal load and available DC source to these numbers before buying.

Questions about this item

How do I install the TES1-7102 module and what step is often missed?

Mount the 23x23x4.5mm plate between a heat source and a heat-sink with thermal paste; the critical step is fitting the heat-sink before applying any power, otherwise the cell overheats and fails in seconds.

What maintenance or replacement will the TES1-7102 need later?

The solid-state module itself has no wearable parts; plan to re-apply thermal paste if the joint dries out and verify the heat-sink fan remains clean so the hot side stays cool.

What limit appears first when the TES1-7102 runs continuously?

The hot-side temperature limit appears first; without adequate heat-sinking the 10W device cannot shed heat, so the internal 65°C differential at 5.78V cannot be maintained and the cell will overheat.
