The PMC-350 C is CET’s latest product designed for the wireless IoT energy metering market, featuring LoRaWAN technology for remote wireless communication. With its standard DIN form factor, measuring 72 x 70 x 95mm, it is ideal for space-constrained environments. The meter comes with a standard RS-485 port and supports the Modbus RTU protocol, conforming to IEC 62053-22 Class 0.5S for 5A input and IEC 62053-21 Class 1 for SCCT/SCCTA input. It optionally supports LoRaWAN frequencies such as AS923-1/2/3/4, KR920, AU915, or EU868, making it a crucial component of smart, distributed, and IoT-based Energy Management Systems (EMS).

The PMC-350 C offers the following optional features:

• 4x Digital Inputs (DI) for status monitoring
• 2x Relay Outputs (RO) for control and alarms or 2x Solid-State Pulse Outputs (SS) for energy pulse signals
• Inputs for temperature and leakage current measurement

• Typical Applications:

  • Metering for industrial, commercial, and utility substations
  • Sub-metering and cost allocation
  • Building, factory, and process automation
  • Energy management and power quality monitoring

  This device is a reliable and scalable solution for advanced metering applications, offering flexible connectivity and compliance with modern energy management systems based on IoT.
