SP1848-27145 Thermoelectric Power Generator

Principle of Heat Generation:

• Thermal Flow: Thermal energy flows into the Peltier module from the high-temperature side.
• Heat to Electricity Conversion: As the thermal energy passes through the module, a part of it is converted into electrical energy due to the Seebeck effect, generating DC voltage and current.
• Voltage Output: You can increase the output voltage by connecting multiple TEG modules in series.

Usage Instructions:

• Module Orientation:

  • Cold End (Heat Dissipating Surface): The side with text ("with word") should be placed against a cooler surface or heat sink.

  • Hot End (Heat Absorbing Surface): The opposite side (non-text side) should be placed against a hotter surface.

• Electrical Connections:

  • The red wire should be connected to the positive terminal.

  • The black wire should be connected to the negative terminal.

  • Power is generated when there is a temperature difference between the two sides.

High Reliability:

• The SP1848-27145 TEG module has no moving parts, making it light, easy to handle, and highly reliable with a long lifespan.

Important Notes:

• When using TEG modules designed for power generation, ensure there is a proper heat sink on the cold side.

• When using a Peltier cooling chip like TEC1-12704, it should not be powered for a long time without a heat sink. Overheating can cause damage to the module, potentially leading to failure or burning of the internal components.

Key Points to Remember:

1. Maintain Proper Heat Flow: Ensure that there is a significant temperature difference between the hot and cold sides to maximize power generation.

2. Heat Dissipation: Always provide adequate cooling on the cold side to prevent thermal overload, especially for cooling modules like TEC1-12704.

3. Avoid Overheating: Be cautious not to overheat the module beyond its rated maximum temperature.
