Power Monitor, AC-Powered

NAI’s PMA and PQA Power Monitors are used to monitor voltage, frequency, and phase characteristics of single- or three-phase power lines. This allows normal operation of system loads when the power line characteristics are within predetermined limits. These power monitors are ideally suited for rugged defense and industrial applications.

Features:

  • AC-powered
  • Single- or three-Phase
  • Operates at 50/60/400 Hz
  • Voltage, frequency, or phase outputs
  • Accuracy ±1%
  • Hysteresis 1% maximum
  • Time delay (pick-up & drop-out) 250 ms to 10 seconds
  • High reliability
  • Versatile design allows for many variations
