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.
- 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
