April 2, 2014 - Oven Industries’ Model 5R7-350/347 thermal controller is especially designed to operate with thermoelectric (Peltier effect) modules. Most of these modules may be operated in either a cooling mode or a heating mode depending on current direction. The 5R7-350/347 thermal controller may be field configured for either of these operating modes. These thermal temperature controllers were designed with a proportional / integral control algorithm to provide the best control at the most economical cost. Either a fixed or adjustable proportional bandwidth and integral rate permits optimizing individual thermal systems. Additional external heat sinking will permit operating load currents in excess of 10 amperes. The thermal controllers are available in both an open board construction or encapsulated on a mounting plate. Various configuration options are available for the type of adjustments offered, packaging, available custom temperature ranges, and dial scale. FEATURES
