AC-Powered, AC Voltage Monitor, Adjustable
VMA - North Atlantic Industries (NAI)
NAI’s VMA is a field-adjustable, AC-Powered, AC Voltage Monitor 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.High and low voltage limits, and "pick-up" and "drop-out" time delay are field-adjustable. The VMA voltage monitor is ideally suited for rugged defense and industrial applications.
