The Elite 500 series includes devices with advanced power

monitoring capabilities, which can be used for standalone
device monitoring and power quality analysis as part of BMS,
process industrial controls and SCADA systems.

It also offers data logging, control IOs and modular

communication with multiple protocols for third party system
integration.

Based on the application, Elite 500 allows customers to select

conventional type CT or Rogowski coil input, which can be
directly connected to the meter without the need for any
additional integrator.
