The APN Series Power Monitoring Sensor from NK Technologies measures three phases of current and voltage, and computes 14 values necessary to track power usage in the RS485 Modbus RTU format. The monitor uses current transformers to measure the amperes. The line voltage connects directly to the transducer, up to 600 VAC. The APN’s RS485 Modbus RTU format is compatible with many PLCs and fits into industrial communications networks, both hard-wired and wireless depending on the specifics of the application.
