1.3 PMC-340’s application in Power and Energy Management Systems
The PMC-340 series meter can be used to monitor Wye connected power system. Modbus
communications allow real-time data and other information to be transmitted across a RS-485 network
to an Integrated Energy Management System such as PecStar® iEMS.
