WTC32ND-14 Temperature Controllers

Output Current TEC ±2.2 A; Chassis Mount; Supply Voltage 7, 9, 12 VDC; Temperature Stability 0.0009°C

Wavelength Electronics’ WTC32ND-14 series of mini-instrument type temperature controllers feature a temperature (not resistance) display and onboard adjustments.

The WTC33ND-14 series is the new version of the discontinued WTC3293-14001 series of temperature controllers.

Wrapped around Wavelength Electronics’ precision WTC32ND TEC driver, the WTC32ND-14 series 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 A. It operates with +7, +9 or +12 V input voltage.

Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard products can be easily modified to meet your application requirements. Get in touch with the AMS Technologies laser diode driver experts to discuss your customized solution!
