5R7-570(A) RoHS-compliant open board electronic temperature controllers feature a proportional integral control algorithm for precise control of thermoelectric modules (Peltier). H-bridge temperature control is said to provide seamless transition between heating and cooling eliminating dead spots. Green LED for heat and blue LED for cooling indicate mode and simultaneous illumination indicates 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. 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.
