The TC LAB series of temperature controllers integrates high-end Digital Control with a precision output current drive stage to offer the best stability temperature control instrument commercially available today. Many different sensors can be used in the feedback loop including thermistors, RTDs, linear current and voltage sensors.

Two models are available driving 10 A(TC10 LAB), maximum with 15 V compliance, or 15 A maximum with 20 V compliance to the thermoelectric or resistive heater.

We are sure that once you experience the precision, stability and ease-of-use of our touchscreen instruments, you’ll be convinced that they are ideal for your high performance application. We are offering a test drive any instrument for 30 days for free.  Activate the test drive.


Safety features protect the thermoelectric [TE] and it’s load. 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 TE, output current is disabled. If temperature limits are exceeded, a signal to the active 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.


With Wavelength’s plug and play instrument, you have the ability to quickly set the controls using either the instrument touch screen or a remote computer, and results are easy to monitor. This allows taking your temperature controlled application from the test bench to market quickly and efficiently.


Wavelength’s proprietary IntelliTune algorithm characterizes the TE/sensor system’s response to the controller and determines the optimal PID control coefficients. It then automatically adjusts the PID control values as setpoint, tuning mode, or bias current change.

Run IntelliTune easily just off ambient and watch it change PID settings for a much higher or lower setpoint. After a single scan, explore either optimized Setpoint Response or Disturbance Rejection performance with your load to see which works best. Add or remove the D term to see if noise is an issue. IntelliTune lets you skip the manual characterization and it’s smart enough to really work—very little adjustment is needed after you have stored a successful characterization scan. See Application Note AN-TC13 for an in depth exploration.


One mating DB 15+2 Thermoelectric and sensor plug is included with the instrument. Single and dual rack mount kits are available. A DB9 mating connector for Status/Enable signals is available (CKT-203). A DB15+2 male connector with hood and high current pin inserts is available (CKT-204). Full cables for the DB9 and DB15+2 are available as WCB405 and WCB406, respectively.

When controlling laser diode temperature, the LDMOUNT-5A, a 14-pin butterfly laser diode mount with integrated heat sinking, is available for simple connections between the instrument and the laser.

If you need a lower power temperature control instrument, consider the 5A LFI3751 Analog, LFI3751 Digital, or the 10A TC10 LAB Temperature Controllers.


The ultra-stable temperature controller instruments are particularly reliable for research in electro-optical, medical, spectroscopy, and defense systems wherever precision temperature control is required.

Free, effective, and responsive technical support is available to simplify integration of Wavelength products into your OEM design. The standard product can be easily modified to meet your application requirements.

The TC LAB Series can be used with the LDMOUNT 14-pin Butterfly Laser Diode Mount.  More recent revisions of the TC LAB have the current capacity to support the TEC Interlock function. The revision is labeled in the third character of the unit’s serial number (LAX123456789). Please see the table below to determine which cable is appropriate for the model of TC LAB being used.
