Model 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. Computer interface is possible via a USB terminal. LabVIEW drivers are included with the computer interface as a standard feature. All pertinent TE parameters, ITE, VTE, temperature sensor (° C, R, Amp, or Volts) are measured and presented on the four line alphanumeric LCD display. 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. PID control is implemented in the Model 3700 that meets all the temperature stabilization requirements for laser diode users. During operation, the front panel controls can be disabled to prevent any changes in the output by accidental misadjustment of the control knob. 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.
