Power Monitor, AC-Powered, Field Adjustable
YMA/YQA - North Atlantic Industries (NAI)
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.
