Product description
A Peltier element uses the thermoelectric effect as a heat pump. When a voltage is applied, a flow of heat is generated between the two ceramic sides; one side is cooled while the other heats up. The TES1 12704 module with a power output of 38 W operates at 12 V DC and typically achieves temperature differences of several degrees Celsius between the cold and hot sides.
The power output depends directly on the applied voltage and current. The temperature difference is determined primarily by heat dissipation on the hot side and heat supply on the cold side. Without adequate heat sinks on both sides, efficiency drops drastically. The element enables applications such as cooling sensors or electronic components, temperature control in portable devices, or rapid thermal testing in the laboratory. Particularly in prototypes, the module enables testing temperature behavior without complex cooling systems.
Operation requires a regulated power supply with at least 12 V and sufficient current capacity; around 3 to 4 A is required at full power. Heat sinks on both sides are essential. Without them, the achievable temperature difference remains low and the element overheats. The polarity of the power supply determines which side becomes hot and which becomes cold; reversing the polarity reverses the function. The element is designed exclusively for laboratory tests and project setups.
Safety information
Incorrect polarity may damage the element. This element is not intended for use in household electrical circuits and is exclusively intended for prototype setups as well as testing and development purposes. Heat sinks and their mounting are the responsibility of the setup; if you have questions about safe integration, consult a qualified electrician.
