Designed with proportional integral control algorithm, Model 5R7-570(A) provides precise control to thermoelectric modules. H bridge unit delivers seamless transition between heating and cooling, eliminating dead spots. Green LED for heat and blue LED for cooling indicate mode, while simultaneous illumination indicates load circuit is off due to open sensor. Measuring 1.75 x 3.5 x 3 in., controller features 6–28 Vdc input voltage, 0–36 Vdc output voltage, and temperature range of -20 to +150°C.
