Elite 500 - Energy transfer measurement and reconciliation Power plants, feeder monitoring, grid substations, wind turbines, renewables, industrial and commercial premises

The Elite 500 series is a set of devices with advanced power monitoring capabilities. It can be used for standalone device monitoring and power quality analysis as a part of the building management system (BMS). It can also process industrial controls and SCADA systems. It offers data logging, the ability to control IOs, and modular communication with multiple protocols for third party system integration. Elite 500 allows customers to select either a conventional type of CT or Rogowski coil input, depending on the application. These can be directly connected to the meter without the need for any additional integer.
