GENERAL DESCRIPTION:

Simply stable temperature control.  Wire your 

thermoelectric cooler and thermistor to the 

board with the cable provided.  Add the 

appropriate DC power supply and indicate the 

expected 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 

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.

WTC3243 Thermoelectric Temperature 

Controller Board with Display

WTC3293-14001

FEATURES:

•   Low noise, maximum temperature stability 

commercially available

•    Display thermistor temperature directly - no 

tables to convert resistance to temperature

•   LED indicator shows over temperature, 

stable at setpoint, or under temperature 

status 

•   Adjust setpoint with a 12-turn potentiometer 

or an external voltage

•   Control temperature using a 10 k

 

thermistor

•   Fixed resistors set Proportional Gain, 

Integrator Time Constant, and 

thermoelectric current limits

•  Enable/Disable Output Current Switch

•   Includes Output Cable

•  Works with a wide range of thermoelectrics
