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 the customer
requirements. Custom configurations are available, 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 16 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)
• Control stability of ±0.13°C (-10° to +50°C)
• 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
