DC-Powered, AC Voltage Monitor
VAD/VQD - North Atlantic Industries (NAI)
NAI’s VAD and VQD are DC-Powered, AC Voltage Monitors used to monitor voltage characteristics of single- or three-phase power lines. This allows normal operation of system loads when the power-line characteristics are within pre-determined limits. These voltage monitors are ideally suited for rugged defense and industrial applications.
