The WTC3293-14401 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 WTC3293-14001 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
