ATFC109D is designed for maintaining the temperature inside an enclosed chamber by driving one TEC or multiple TECs and a fan array with the working status and parameters monitored and displayed at the same time. The controller integrates a micro-controller, a digital display, a few buttons and indication LEDs, a bidirectional TEC H bridge output stage and a fan driver, and it can be used for driving and monitoring TEC/Fan assemblies, and displaying in real time important parameter values and status of the controller on both the controller and the computer.
