Wavelength introduces TC15 LAB temperature controller

November 21, 2017 – Wavelength Electronics introduced the TC15 LAB (15A, 20V), a digital controller for thermoelectrics and resistive heaters where tight temperature stability is required. Stability better than 0.0009°C can be achieved with thermistors.

This 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.

This temperature controller offers:

  • Stability (0.0009°C) at 15 Amps up to 20 Volts to a thermoelectric or resistive heater
  • Touchscreen front panel – see setpoint, actual temperature, stability status all on one screen
  • Safety – shut down laser / QCL / active load if it goes outside user set temperature limits. Auxiliary sensor can monitor heat sink temperature.
  • Remote Command set – control and log data from a remote computer via USB (Test & Measurement Class) or Ethernet
  • Free LabVIEW VI executable for 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.

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.
