Oven Industries Model 5R7-350A RoHS Series is an economical, open board temperature controller 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 5R7-350A RoHS Series may be field configured for either of these operating modes.
These 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. The controllers are capable of providing up to 7.5 amperes of current for modules rated at 9 through 26 volts DC with a mounting plate temperature of 25°C. Additional external heat sinking will permit operating load currents in excess of 10 amperes.
