Modbus kWh Revenue Meters
Intro
Features
Communication with Host
This latest generation of revenue meters supports the Modbus protocol over the RS485 interface for remote auto meter reading, some units even have a built-in relay for remote power disconnection and restoration
Load Wiring
Pass-through: The live wire of the load is directly connected into the meter, this type of connection is limited to 80 amperes.
External CT: For loads greater than 80 amperes, external CTs are used. The load is passed through the primary, while the secondary 5A output of the CT is connected to the meter.
