Newport Corporation’s Model 3700 temperature controller provides a 336W bipolar output for operation with thermoelectric (TE) coolers.

At the heart of the unit, 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, according to Newport.

Computer interface is possible via a USB terminal.

Labview drivers are included with the computer interface as a standard feature.

All pertinent TE cooler parameters are measured and simultaneously 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 the need for additional interface units.

Sensor calibration constants are easily programmed for direct readout in Celsius.

PID control is implemented in the Model 3700 that meets all the temperature stabilisation 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, high- and low-temperature limits, voltage limits, sensor open and TE open detection.

To prevent noise pickup, either by the output lines or the sensor inputs – resulting in undesirable temperature oscillations – shielded cables are also available.
