The TC-XX-SR-54 temperature controller is a microcontroller based device that can be incorporated into a thermoelectric cooler assembly to add integrated temperature control. TC-XX-SR-54 is a bi-polar temperature controller for cooling/heating of thermoelectric cooler assemblies requiring precise temperature control accuracy. The TCXX-SR-54 has thermoelectric cooler outputs, three programmable fan outputs, alarm output relay, alarm condition LEDs, three temperature sensor inputs. The parameters will be programmed at the factory according to the customer requirements. Custom configurations are available, however MOQ applies.
