High-precision, multiple communication, TFT display

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 offer 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.
