Description

The 12V Peltier TEC1-12705 Cooler Module is a thermoelectric cooling device used to transfer heat from one side to another, providing efficient cooling for small electronic devices. Powered by a 12V DC supply, it utilizes the Peltier effect to create a temperature difference, with one side becoming cold and the other hot. This module is ideal for cooling applications like portable coolers, small electronic devices, and temperature-controlled systems.

Short Specifications:

Voltage: 12V DC
Current: 5A (max)
Power: 60W
Temperature Differential: Up to 67°C
Size: 40mm x 40mm
Application: Electronic cooling, small devices, portable coolers
