TEC1-12712 THERMOELECTRIC COOLER PELTIER 40x40mm

The TEC cooler normally works with heat sink or liquid cooling block. This can help to protect the TEC cooler from being overheating. Also they can work together for better cooling effect.

Specification:
Material: Ceramic (Both surface), semiconductor material (Between two ceramic plates)
Dimensions(D*W*H): 40 mm x 40 mm x 3.8 mm
Peltier elements (Couples): 127
Suggested Voltage range : 12 Volt to 15.4 Volt
Max current: 12 A @12 Volt
Maximum cooling power Qcmax: 115 Watt
Maximum temperature differential (Tmax @ Qc = 0): 72 °C
DC Resistance: 1.3-1.5 ohm

How to Install:
The TEC cooler is very simple to install and use. Before installation, make sure the cooler is dry, then connect the two leads of the cooler to the power supply (red (positive) and black (negative) ), you can feel cold at one end and warm at the other end. For best cooling effect, you'll need to get off that heat. Otherwise the cold side will slowly get warmer. A fan and/or heat sink is ideal for work together with the cooler.
The following figure shows the positive/negative lead and cold/hot side of the TEC cooler.
