TEC Module Thermoelectric Cooler Peltier Module 127 Pairs 3A 15.4V 20W 30mm*30mm*3.6mm DTmax 66 degC with Non-sealed Edges ATE1-127-3A

This TEC module has 127 pairs of Peltier elements inside with a maximum voltage of 15.4 Volt. It is designed for regulating the temperature of the target objects precisely and can be controlled by our TEC controllers to build highly stable and efficient temperature regulating systems. It can be used with our thermistors as well to achieve precise and stable temperature sensing. It comes in with highly flat bare ceramic surfaces on the both sides, they can be mounted onto flat metal surfaces by inserting thin layers of thermally conductive filler materials, the so-called thermal pads, or placing a thin layer of thermal paste.

When mounting, make sure that proper pressure is applied constantly to keep good thermal contacting between the metal and the TEC plates, minimizing thermal resistance between them.
