or a relay strategy is implemented by the FP-5000 processor.
ADC Analog-to-Digital Converter.
ADT Adjustable Definite Time is the time value provided by the user
as fixed reset delay independent of current.
Analog Signal Currents and voltages are analog signals.
Apparent Power Factor Real power (watts) divided by volt-amperes (using the true rms values).
ASCII American Standard Code for Information Interchange.
