The Oven Industries open-board temperature controller is designed with a proportional integral control algorithm to provide control to thermoelectric modules. The H bridge control provides a seamless transition between heating and cooling, while pulse width modulation controls the power level in the thermoelectric module at a base frequency of 900Hz. The controller features 0.1°C temperature resolution, +/-0.1°C control stability and a temperature range of -40°C to 250°C.
