One or more of the controls can be utilized in any servo circuit depending on system demand and requirement (i.e., P, I, PI, PD, or PID). Proportional control is proportional to the error signal; as such, it is a direct response to the error signal generated by the circuit: Larger proportional gain results is larger changes in response to the error, and thus affects the speed at which the controller can respond to changes in the system. Is there any a temperature sensor you suggest working with ITC4020 in the range between minus 150C and plus 200C? These features make the ITC4000 Series an ideal choice for safe and secure operation of medium- to high-power laser diodes and LEDs either in the lab or in production environments.
