Original Press Release:
New - 15A / 20V Precision Temperature Control Instrument
The TC15 LAB (15A, 20V) is an ultra-stable digital controller for thermoelectrics and resistive heaters where tight temperature stability is required. Designed using the latest technology, stability better than 0.0009°C can be achieved with thermistors. Precision temperature control is required in myriad applications. This high-powered controller makes development of complex systems or sophisticated experiments possible in biological sample control, laser diode or quantum cascade laser wavelength stabilization, spectroscopy, remote sensing, imaging, aerospace, communications, materials processing, pharmaceutical manufacturing control, environmental sensing, electro-optics, and more.
ULTRA-STABLE TEMPERATURE CONTROLLER
This best-in-class temperature controller offers:
- Excellent stability (0.0009°C) at 15 Amps up to 20 Volts to a thermoelectric or resistive heater
- Intuitive touchscreen front panel – see setpoint, actual temperature, stability status all on one screen!
- Extra safety – shut down your laser / QCL / active load if it goes outside user set temperature limits. Auxiliary sensor can monitor heat sink temperature.
- Expanded Remote Command set – control and log data from a remote computer via USB (Test & Measurement Class) or Ethernet
- Free LabVIEW VI executable for easy remote computer control
- IntelliTune® optimizes PID control values to minimize time to temperature or reject external disturbances
- IntelliTune® keeps adapting the PID control values as setpoint, tuning mode or sensor bias current is changed
- Compatible with all sensors – thermistor, RTD, LM335, AD590.
SAFETY IS BUILT IN
Over and under temperature limits as well as positive and negative current limits can be set. If the sensor signal is lost or a short is detected at the thermoelectric, output current is disabled. If temperature limits are exceeded, a signal to the active laser load can be sent to disable its current. For example, connect the LD Shutdown BNC output to the Active Lock input on Wavelength’s QCL LAB driver and the QCL current will shut down if temperature limits are exceeded. An Auxiliary Sensor can be used to monitor the temperature of the system heatsink.
Instead of long, manual calculations to derive the optimal Proportional, Integral, and Derivative [PID] control terms for a load, press the IntelliTune icon and the instrument will automatically cycle through a characterization test to tune the control terms for best performance. Two methods of IntelliTune are available. Setpoint Response optimization will minimize the time to temperature for the load. Disturbance Rejection optimization is best when there will be significant changes to the ambient temperature or operating condition. This could be for a pulsing laser diode where the active heat load changes or a sample that is to be tested in changing ambient temperatures.
