Bi-Directional Temperature Controller
The 5R7-388 RoHS-compliant temperature controller from Oven Industries, Mechanicsburg, Penn, offers bi-directional control for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications. The “H” bridge configuration of the solid state MOSFET output devices allows for the bi-directional flow of current through the thermoelectric modules. The PC-programmable controller includes 36V DC output; a PC-configurable alarm circuit; proportional (P), integral (I), and derivative (D) control that can be selected as P, PI, PD, or PID, as well as on/off with adjustable hysteresis. Input voltage is 12 to 28 volts DC; output load rating is 0.1 to 25 amperes. For more information, visit Oven Industries.
