High Efficiency TEC/Peltier Controllers and Their Associated Components

TEC (Thermo-Electric Cooler, or Peltier Cooler) is a semiconductor device which can cool down or heat up the temperature of a thermal load depending on the direction of the current going through the two terminals of the TEC. By using a TEC controller, the thermal load temperature can be regulated precisely by controlling the direction and magnitude of the current going through the TEC.

We have a variety of TEC controllers.

TECA1-xV-xV-D series TEC controllers feature high efficiency, high stability, high reliability and compact sizes. The maximum current is 2.5A. They are often used for controlling temperature in laser systems.

TEC5V4A-D is almost the same TEC controller as the above TECA1-xV-xV-D TEC/Peltier controller, except that the maximum output current is 4A, as opposed to the 2.5A.

TEC5V6A-D TEC controller has the same pin out as the above 2 TEC controllers.

ATEC24V10A-D TEC controller is under development. It allows high input voltage, high output current, works under high power efficiency, and has a small size.

ATFC106D is a digitally controlled TEC controller. It comes with a key pad and a digital display, can be programmed on the field, has a high input voltage and high output current capability.

Many of these TEC controllers work well with our TEC Modules, Thermistors and Thermally Conductive Epoxy.

ATW3A314 (Under Development)

ATW3A314

ATW3A314 is a compact high efficiency electronic module, designed for controlling TECs (Thermo-Electric Coolers) for regulating a target object temperature to be within a pre-set temperature window. The main advantage to use this controller is to save energy for battery powered systems: during most of the operating time, the target is within the preset window, and the TEC controller is not turned on, only occationally, the target temperature falls outside the preset window and the TEC controller is turned on to bring the target temperature back to be within the limits.

TEC28V15A

This TEC controller, TEC28V15A, 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 9V to 28V and output current can go up to 15A without using a heat sink.
