DC Powered AC Voltage Monitor
Overview
The VAD and VQD are DC Powered AC Voltage Monitors. These Voltage Monitors are used to monitor voltage characteristics of single or three-phase power lines, allowing normal operation of system loads when the power line characteristics are within pre-determined limits.
