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, TEC9V7A, 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 6V to 9V and the output current
can go up to 7A without using a heat sink.
