Press Release Summary:

June 10, 2014 - Factory-configured with 0–500 A or 0–2,000 A flexible coils to measure load current, DIN mounted APN-R Series can measure power usage of one piece of equipment, machine system, plant area, or entire facility. Line voltage (up to 600 Vac) connects directly to transducer, and installation over multiple conductors or bus assemblies produces accurate data while also allowing intervention. Digital format provides information on system voltage, current, and power factor in addition to wattage.

Original Press Release

New Power Monitor from NK Technologies Can Track Power Usage for a Single Piece of Equipment, or an Entire Facility

Press release date: June 2, 2014

SAN JOSE, CA – NK Technologies introduces the APN-R Series Power Monitor, which measures the power usage of a single piece of equipment, an extensive machine system, an area of a plant, or an entire facility. The APN-R is equally suited for large scale plant energy management applications, as well as specific equipment monitoring tasks, such as detecting conveyor jams and overloads, or identifying dry running pumps caused from clogged intake or discharge lines, impeller cavitation or bearing wear.

The APN-R is factory configured with 0-500 A or 0-2000 A range flexible coils to measure the load current. The line voltage (up to 600 VAC) connects directly to the transducer; no potential transformer is needed unless the line voltage exceeds 600 volts. The ease of installation over multiple conductors or bus assemblies speeds installation and produces an accurate set of data that will identify areas of excessive energy consumption and allow intervention to reduce demand.

The APN-R measures three phases of current and voltage, and computes fourteen values necessary to track the power usage. The monitor's digital format provides information on the system voltage, current, and power factor in addition to wattage. The monitor fits seamlessly into industrial communications networks, both hard wired and wireless depending on the specifics of the application. The RS485 Modbus RTU output reduces the cost involved with proprietary data logging software and is compatible with most automation systems. There is also a pulse contact which opens and closes as watt hours are accumulated.

Other features of the APN-R include: 24 VAC/DC, 120 or 240 VAC external power supply for improved reliability when used in conditions where power interruptions and voltage sags are common; compact, low profile DIN mounted housing to reduce cabinet depth requirements; clearly labeled finger-safe terminals for safe, secure connection and quick installation; and LED display for quick visual indication of network communication. The APN-R is designed to meet UL, CUL and CE Approval.

NK Technologies offers no-cost test and evaluation units to qualifying OEMs. Visit the Engineering Resources section of NK Technologies website for access to numerous application notes and a technology white paper on current sensing technology.
