The ITC4000 automatically selects the optimal PID parameters for the current thermal setup. 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). Additionally, these controllers can be controlled by a SCPI-compatible USB Interface. Thorlabs Laser Diodes, Unbiased LASER DIODE SELECTION GUIDE, Compare all Manufacturers and Product Data Sheets on One Site, 370nm to 2350nm. and how coudl i got the correct thermopile voltage under QCW operation? This Profile LDC1000 Laser Diode Controller is used, and in excellent condition. A response from Stefan at Thorlabs. Here the measurement screen is configured to 2 values. I will contact you directly to discuss your application in detail. Can you please let us know the repetition rate, pulse width, and cooling requirements. Is there any a temperature sensor you suggest working with ITC4020 in the range between minus 150C and plus 200C? Use the legend below to quickly select the driver with the features that you need. Gains are for various control circuits are then given below in the chart. For more details about these features please see the More Info tab. in the case of a PT100 sensor, the resistance of the PT100 changes as a function of the temperature and the controller can only measure these changes accurately within a range of -55°C to +150°C. Stefan Hallwig. The tables below are designed to give a quick overview of the key specifications for our laser diode controllers and dual diode/temperature controllers. 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. For more information about the constant current and constant power modes, the photodiode and thermopile monitor inputs, the continuous wave (CW) or quasi-continuous wave (QCW) operation and the enhanced protection features for the laser diodes please see the More Info tab. Package Weight: 20.38 lbs / Each: Discontinued: Feb 15, 2010: Drawings and Documents: Catalog Presentation: Manual : RoHS: REACH: Download all support documents: … If you have any questions, please contact your local Tech Support team. In general a PID circuit will typically overshoot the SP value slightly and then quickly damp out to reach the SP value. 3. It combines the benchtop LD Current It combines the benchtop LD Current Controller LDC205C and the benchtop Temperature Controller TED200C and other required items for a stable and safe operation of standard laser diodes. Temperature setpoint and actual reading are accessible for convenient testing. All technical data valid at 23 ± 5 °C and 45 ± 15% relative humidity. The integrated pulse generator can be triggered internally with an adjustable repetition rate or externally via a BNC jack at the rear of the unit. We offer a full SDK for the ITC4000 lines. They allow space-saving simultaneous current and temperature control of a laser diode with a single module. The three controls relate to the time-dependent error signal; at its simplest, this can be thought of as follows: Proportional is dependent upon the present error, Integral is dependent upon the accumulation of past error, and Derivative is the prediction of future error. Depending on the selected measurement range. I want to make sure that temperature control range in between -150 Celius and plus +200 Celcius for PT100. Thank you in advance, Integral control goes a step further than proportional gain, as it is proportional to not just the magnitude of the error signal but also the duration of the error.
