Description

PMC-340 Digital Three-Phase Energy Meter


Device Introduction
  • The PMC-340 Series Digital Three-Phase Energy Meter is CET's latest offer for the low voltage power/energy metering market featuring DIN-Rail mount, high accuracy, multifunction true RMS measurements and a large, easy to read LCD display.
  • The PMC-340 complies with the IEC 62053-21: 2020 Class 0.5 and IEC 62053-22: 2020 Class 0.5S kWh Accuracy Standards for 100A Direct Input and 5A CT Input, respectively. The PMC-340 comes standard with a LED as well as a Solid State Pulse Output for energy pulsing. The standard RS-485 port and Modbus protocol support allows the PMC-340 to become a vital component of an intelligent, multifunction monitoring solution for any Power and Energy Management Systems.
