NK Technologies: Power Monitor

The APN-R Series Power Monitor measures the power usage of a single piece of equipment, an extensive machine system, an area of a plant, or an entire facility.

The unit can be used for large scale plant energy management applications or 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. It 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 monitor measures three phases of current and voltage, and computes fourteen values necessary to track the power usage, including information on the system voltage, current, and power factor in addition to wattage. The RS-485 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.
