Model 5R7-350 is an economical, open board temperature controller especially designed to operate with thermoelectric (Peltier effect) modules. The temperature controller can be field configured for either cooling or heating mode. These controllers were designed with a proportional integral control algorithm to provide the best temperature control at the best price. Either fixed or adjustable proportional bandwidth and integral rate permits optimizing of individual thermal systems. This model is capable of providing up to 7.5A of current for modules rated at 12 to 24VDC with a mounting plate temperature of 25°C. Additional external heat sinking will permit operating load currents in excess of 7.5A.
