Description

PMC-352 3-Phase LoRa DIN Energy Meter


Device Introduction

  • PMC-352 3-Phase Wireless DIN Rail Energy Meter is CET’s latest offer for the wireless loT energy monitoring market using the LoRa technology for its Wireless communication capability. Designed in a compact DIN form factor measuring 36x65x90mm, it is perfect for energy and condition monitoring applications in space-limited power distribution board.
  • The PMC-352 comes standard with 4xNTC Inputs for temperature monitoring and 3xDI for status monitoring. With standard RS-485 and optionally LoRa supporting the Modbus RTU protocol and IEC 62053-21 Class 1 compliance, the PMC-352 becomes a vital component of an intelligent, distributed and wireless loT based EMS or Condition Monitoring System.
