Supplied in 1.75 x 3.5 x 3 in. package, 5R7-570(A) RoHS-compliant open board electronic temperature controller has -20 to 150°C range and ±0.1°C control stability. Proportional integral algorithm provides precise control to thermoelectric modules, and H-bridge temperature control provides seamless transition between heating and cooling. While PWM controls power level in thermoelectric module at base frequency of 1 KHz, power resolution is one of ±250 steps in load circuit control.
