FQ1085
FQ1085:    Do the temperature controllers always provide full current to the driven element (a TEC or Peltier device, or resistive heater) when the actual temperature does not equal the set point temperature?
 
Applies to these products:
 
  • WHY5640
  • With all of the Wavelength Electronics temperature controllers, when the actual temperature of the load being temperature controlled is greatly different from the set point temperature, the controller will source up to the maximum current (depending upon configured current limits and any compliance voltage or current limiting considerations) to the driven element. As the actual temperature voltage approaches the set point temperature voltage, the output current from the controller will be ramped back and reduced according to the PID configuration until a semi-steady state current level is maintained at (or very near) the settled, set point temperature.
