The LDT-5940C was designed for customers requiring higher power and high stability. This new temperature controller with digital PID control loop achieves temperature stability of less than ±0.003°C with output current noise and ripple less than 2mA rms. For fast setup, the LDT-5940C incorporates preset PID values and a fast auto-tune PID mode that automatically determines optimal PID values. The LDT-5940C is compatible with a wide range of sensors including thermistors, RTDs, LM335, and AD590 IC sensors. A new linearized thermistor sensor mode allows the LDT-5940C to achieve ±0.2°C temperature accuracy over a wide temperature range from -30°C to 85°C with standard 10K? thermistor. Interlocks allow the user to connect the LDT-5940C to a laser diode driver and will disable the laser output if the LDT-5940C is disabled or is over the user-configurable temperature limit. An additional feature of the LDT-5940C is an analog voltage input for temperature sweeping or tuning without using a remote interface or front panel control.
The LDT-5940C includes USB 2.0 and IEEE 488.1 GPIB interfaces for remote instrument operation in R&D or manufacturing environments. LabVIEW® drivers for the LDT-5940C are available for download from the ILX Lightwave website.
