Laird Technologies announced its new Q Series Thermostatic Controller for most Thermoelectric Assemblies (TEAs). The Q Series Thermostatic Controller is a microcontroller-based device that adds integrated temperature control to a TEA. The controller functions as a single directional unit that offers heating or cooling temperature control to the device. Products in this series include TC-18-QC-50 and TC-18-QE-50. Programming of advanced controller options and features is available to meet unique application configurations. All programming is conducted in-house by Laird Technologies Engineering. Features include alarm shutoff, upper and lower temperature limits, upper and lower voltage limits, and tachometer limits. The temperature set point ranges from -20°C to 50°C and can be adjusted with an internal or external potentiometer.
