Installations are becoming more and more demanding, some of them powering critical loads, so power quality with harmonic analysis is vital. Carlo Gavazzi’s range provides various mounting and installation solutions to meet different application requirements. In many cases the meters, in an electrical installation, have to measure high currents, which is why Carlo Gavazzi offers a comprehensive range of current transformers, compatible with both the main meters and the submeters.• Panel mounting• 208 or 690 VAC, 5 AAC• Class 0.5S (kWh), 0.2% RDG (V, A)• Up to 6 inputs, up to 8 outputs, optical port, Modbus RS485 and Ethernet, BACnet MSTP and IP, Ethernet/IP, Profibus• Approvals: CE - cULusModular power quality analyzer WM40• Panel mounting• 208 or 690 VAC, 5 AAC + TCD• Main unit: Class 0.5S (kWh), 0.2% RDG (V, A).
