NAI's Power Monitors are used to monitor voltage, frequency, phase characteristics, or phase rotation of single- and three-phase power lines. Specifically designed for rugged defense and industrial applications, these Power Monitors meet the most stringent performance and environmental requirements.
NAI's AC- and DC-powered AC voltage monitors are used to monitor and measure voltage characteristics of single- and three-phase power lines. Field-adjustable AC voltage monitors are also available. These monitors are specifically designed for rugged defense and industrial applications.
NAI's AC- and DC-powered Phase Monitors are used to protect three-phase loads from damage due to phase reversals or phase absence. Contacts may be used to disconnect the load or to operate alarm circuits or both. Upon application of power, the output relay energizes if all phases are connected and the phase sequence is ABC. If any phase becomes disconnected or if the phase rotation is abnormal, the relay immediately de-energizes. These monitors are specifically designed for rugged defense and industrial applications.
NAI’s Aircraft Warning, Navigation Light, and Position Light Flashers are general purpose, solid state, and low-current units. Designed for airborne use, these units conform to all military specifications. All components are rigidly mounted within the fully encapsulated and hermetically sealed flasher assembly.
