3700 Temperature Controller

The 3700 TEC Controller provides a 336 W bipolar output for operation with thermoelectric (TE) coolers and replaces legacy Model 3150. At the unit's heart, DSP based controls allow for PID settings with fast settling times. This feature combined with sound electronics design and quality components results in great temperature stability and higher reliability.

Protection features include: ITE Limit, Hi and Lo Temperature Limits, Voltage Limits, Sensor Open and TE Open Detection. To prevent noise pickup, either by the output lines or the sensor inputs, shielded cables are also available. All standard temperature sensors including thermistors, platinum RTD, AD590/592 and LM335 IC sensors are supported without an additional interface needed. Sensor calibration constants are easily programmed for direct readout in °C.

Computer interface is possible via a USB terminal. LabVIEW drivers are included with the computer interface as a standard feature.

We offer a wide variety of precision laser diode mounts with plug and play compatibility with our laser diode instrumentation.
