TEC (Thermo-Electric Cooler) is a semiconductor
device which can cool down or heat up the
temperature of an object by injecting an electrical
current in one or the other direction. This TEC
controller, TEC18V15A, is designed to drive a TEC at
high efficiency for regulating the object temperature
precisely by controlling the direction and magnitude of
the current going through the TEC. It is powered by a
DC voltage between 5.5V to 18V and the output
current can go up to 15A without using a heat sink.
Figure 1 is photos of the actual controller
TEC18V15AD, one shows the signal pins, and the
other shows the power pins.
