TC-XX-SR-54 Temperature Controller A 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.
