PMC-220 Din Rail Single Phase Electronic Energy Meter

The PMC-220 single phase electronic energy meter is CET’s latest offering for the low voltage energy metering industry, incorporating DIN Rail installation, small construction, 63A direct connect input, and high accuracy measurements. The IEC 62053-21: 2020 Class 0.5 kWh Accuracy Standard is met by the PMC-220.

Furthermore, the PMC-220 din rail single phase electronic energy meter has been verified by UL using NMI M6-1 Electricity Meters, Part 1: Metrological and Technical Requirements, and has been awarded a Certificate of Approval by the National Measurement Institute (NMI) of Australia. The PMC-220 becomes an essential part of an intelligent, multifunction monitoring solution for any Energy Management System when it is equipped with the standard RS-485 connector and Modbus RTU protocol.
