The WTC32ND-14 is a mini-instrument temperature controller with a temperature (not resistance) display and onboard adjustments.

Wrapped around the precision WTC32ND temperature controller, it is configured for use with a TCS610 thermistor. Wire your thermoelectric cooler and thermistor to the board with the cable provided. Add the appropriate DC power supply and indicate the input voltage on the jumper. With the output disabled, adjust the on-board 12-turn trimpot and watch the setpoint temperature change on the 4-digit display. Switch to Actual temperature and display your thermistor temperature. Watch the LED tree to see “over/under temperature” or “stable at setpoint” status. Enable the output current and watch the temperature quickly lock in on the setpoint.

The green LED on the In-Range indicator lights when actual temperature is within 0.05°C of the setpoint. If the actual temperature exceeds the setpoint, the upper LED will light. If it is below the setpoint temperature, the lower LED will light.

The WTC32ND-14 has been designed to work with various thermoelectrics driving up to ±2.2 Amps. It operates with +7 V, +9 V, or +12 V input voltage.

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.

Size (with WTC32ND and heatsinking installed): 2.25″ x 2.7″ x 2.7″ [57 x 69 x 69 mm]
