Power Monitor, AC-Powered, Field Adjustable

NAI’s YMA and YQA 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.

High and low voltage and frequency limits, and "pick-up" and "drop-out" time delay are field-adjustable using potentiometers. These power monitors are ideally suited for rugged defense and industrial applications.

Features:

  • AC-Powered
  • Operates at 50/60/400 Hz
  • Accuracy ±1%
  • Hysteresis 0.5% maximum
  • Time delay (pick-up & drop-out) 250 ms to 10 seconds - adjustable
  • High reliability
  • Versatile design allows for many variations
