The unit is equipped with a 5-digit, 7-segment illuminated display. The unit can be interfaced to a PC using a USB cable and all of the parameters can be set using the included software. The various parameters, such as temperature set point, current limit, temperature sensor type, and PID parameters, are adjustable from the front panel interface for quick and easy local control. The highly precise, closed-loop control is suitable for many applications. It is designed to drive an external Peltier effect thermoelectric heater/cooler coupled to a standard thermistor or IC sensor. The TTC001 T-Cube TEC Controller is designed for high-precision thermal control of small temperature sensitive components.
