WTC3293-14001
WTC3243 Thermoelectric Temperature
Controller Board with Display
GENERAL DESCRIPTION:
Simply stable temperature control. Wire your
thermoelectric cooler and thermistor to the
board with the cable provided.
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.

- Page 3 OPERATING THE WTC3293-14001 1. SELECT POWER SUPPLY VOLTAGE and INSTALL JUMPER The WTC3293-14001 has been designed to operate at one of three discrete voltages: 7V, 9V, or 12V. The POWER jumper must be installed for the chosen voltage. To choose the appropriate voltage for your application, use Wavelength’s online Safe Operating Area (SOA) calculator for Temperature Controllers: www.teamwavelength.com/support/design-tools/soa-tc-calculator/.

VIEW THE SETPOINT and ACTUAL TEMPERATURE The switch next to the setpoint potentiometer determines whether Setpoint or Actual temperature is displayed. When the setpoint is displayed, the rightmost decimal point is lit. The resistance to temperature conversion software assumes the thermistor bias current is 100 µA and the thermistor is...
