Description

PMC-350-C Three-Phase LoRaWAN DIN Energy Meter


Device Introduction
  • PMC-350-C 3-Phase DIN Energy Meter is CET’s latest offer for the wireless IoT energy metering market using the LoRaWAN technology for its Long-Range wireless communication capability. Housed in a standard DIN form factor measuring 72x70x95mm, it is perfectly suited for extremely space restricting environment. With a standard RS-485 port and Modbus RTU protocol support, IEC 62053-22 Class 0.5S and IEC 62053-21 Class 1 compliance for 5A Input and SCCT/SCCTA Input respectively as well as optional support for LoRaWAN AS923-1/2/3/4, KR920, AU915 or EU868, it becomes a vital component of an intelligent, distributed and IoT based EMS.
  • The PMC-350-C optionally provides 4xDI for Status Monitoring, 2xRO for Control and Alarming or 2xSS Pulse Output for Energy Pulsing as well as 2 or 4xRTD and 1xIresidual Input for Temperature and Leakage Current measurements, respectively.
