Oven Industries' offers a high-power temperature controller mounted on a heat sink that creates a seamless transition between heating and cooling devices. Suitable for applications greater than 15 A, the controller serves as the commander of thermoelectric modules. Features include a bi- or uni-directional H-bridge configuration and included, user-friendly PC software for changes to temperature control configurations, eliminating interference or errant signals. The software also enables the temperature controller to operate as a stand-alone unit. A computer can be connected to the device for retrieving data, and temperature settings are controlled through the remote potentiometer and the optional display. Controllers are suitable for the defense and aerospace industries.
