AC-Powered, AC Voltage Monitor

NAI’s VAA and VQA are AC-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.

Features:

  • AC-powered
  • 50/60/400 Hz
  • Accuracy ±1%
  • Hysteresis 0.25% typical
  • Time delay (pick-up & drop-out) 250 ms to 10 seconds
  • High reliability
  • Versatile design allows for many variations
