Overview
The TEC1-12712-50 is a high-performance thermoelectric cooler designed for applications where a standard 40mm plate is simply too small. By expanding the surface area to 50mm x 50mm, this module allows for more efficient heat exchange and better contact with large-format liquid cooling blocks. Rated at 12 Amps, it delivers a powerful 150W of cooling capacity, making it the preferred choice for industrial-grade DIY refrigerators, laboratory equipment, and specialized cooling for high-power electronics.
Key Features
Large 50x50mm Surface: Provides 56% more contact area than standard Peltier plates, reducing “hot spots” and improving thermal transfer.
150W Cooling Power: 12-Amp current rating allows for rapid temperature drops in larger volumes of air or liquid.
Precision Temperature Control: Perfect for applications requiring stable, controlled environments like vaccine storage or chemical processing.
Solid-State Durability: No moving parts, no noise, and no maintenance required.
Bi-Directional Capability: Switch between heating and cooling modes by simply reversing the DC power polarity.
