TC-XX-SR-54 Temperature Controller

The TC-XX-SR-54 temperature controller is a microcontroller based device that can be incorporated into a thermoelectric assembly (TEA) to add integrated temperature control. The TC-XX-SR-54 is a bi-polar temperature controller for cooling/heating of thermoelectric assemblies requiring precise temperature control accuracy. The TC-XX-SR-54 has 3 programmable fan outputs, alarm output relay, alarm condition LEDs. The parameters will be programmed at the factory according to your specifications, however MOQ applies.


  • Operation in Cooling and Heating Modes
  • Regulation mode is ON/OFF, PID, Power
  • Input power range can accommodate 16 to 60 VDC, nominally 24 to 48 VDC
  • Preprogrammed set points
  • Contacts are available for fans, thermoelectric modules, NTC thermistor sensor, overheating thermostat switch, alarms; some features sold on custom configurations only
  • USB communication interface
  • Standalone operation
  • Control temperature, from -20°C to +100°C (-4°F to 212°F) with the standard NTC sensor
  • Temperature resolution of max 0.13°C (-10°C to 50°C)
  • Use with NTC sensors only
  • Pulse width modulation of output: (Base frequency of 8 kHz)
  • Three alarm temperature sensor inputs with adjustable alarm set points
  • Alarm relay output, normally closed (will open on alarm): 1A at 125VAC/110VDC
  • Adjustable fan speed
  • Tachometer sensor inputs provided to measure the speed of one external and two internal fans
  • Overheating thermostat switch input available to sense an over temperature condition that will turn off power to TEA/fans and microcontroller; a thermostat is required for operation
  • Alarm LED outputs available indicate type of failure
