2.3. TSC 80e CONTROLLER FEATURES
The Thomson Technology TSC 80e Transfer Switch Controller utilizes the latest
advancements in microprocessor technology, printed circuit board assembly and software for
control of automatic transfer switches. The TSC 80e is the second generation of
microprocessor-based transfer switch controllers from Thomson Technology, and reflects over
30 years of transfer switch control experience. The TSC 80e is factory configured to monitor,
display and control all operational functions of the automatic transfer switch. All voltage
sensors and timers are fully user adjustable utilizing software configuration. The
microprocessor design provides high accuracy for all voltage sensing and timing functions as
well as providing many standard features.
