5R7-570(A) RoHS compliant open board electronic temperature controllers are designed with a proportional integral control algorithm to provide control to thermoelectric modules (Peltier). H-bridge temperature control provides transition between heating and cooling. Green LED for heat and blue LED for cooling indicate mode; simultaneous illumination indicates the load circuit is off due to an open sensor. Pulse width modulation controls power level in thermoelectric module at a base frequency of 1Khz. Power resolution is one of ±250 steps in the load circuit control. Temperature controller is 1.75" x 3.5" x 3" with input voltage of 6 to 28VDC, output voltage of 0 to 36VDC, load current of 0.1 to 12.5A, 450W output power control, control stability of ± 0.1°C, and temperature range of -20° to 150°C.
