Oven Industries’ 5R7-570(A) RoHS-compliant, open-board temperature controller was designed with a proportional integral control algorithm to provide precise control to thermoelectric (Peltier effect) modules at an economical price.
The H bridge control provides a seamless transition between heating and cooling eliminating dead spots. Green LED for heat and blue LED for cooling indicate mode, and simultaneous illumination indicates the load circuit is off due to an open sensor. Pulse width modulation controls the power level in the thermoelectric module at a base frequency of 1Khz.
The controller features an input voltage of 6 to 28VDC, output voltage of 0 to 36VDC, load current of 0.1 to 12.5 amps, 450W output power control, and control stability of ± 0.1°C and a temperature range of -20 to 150°C.
