IEC Poly Phase Smart Meter

Designed for residential and small commercial energy consumers, our IEC/DIN Poly Phase Smart Meter supplies a comprehensive portfolio of revenue-grade features — and consistently reliable, accurate operation using bidirectional power line communications.

  • Load profiling; billing for time-of-use, prepay, and optional max demand; power-quality analysis; remote-controlled disconnect/reconnect switch; comprehensive display, home area networking support; bidirectional power line communications
  • Tamper-events detected, logged and communicated even during a power failure; Energy measurement technology highly resistant to DC magnetic fields
  • Optional serial multipurpose expansion port (MEP) allows secure hardware extensions for communication with in-home devices, gas and water meters. Optional CNX 3000 for power line and CNX 2000 for ZigBee modules can be used to connect to building information and control devices for home area network management.
  • Forward, reverse, net active energy, kvarh import/export, and four-quadrant kvarh measurements enable customer micro-generation sources and power quality monitoring
  • Each meter acts as repeater  to reach other meters and establish a power line mesh network that shows the real topology of the low-voltage distribution system

For full specifications, see the IEC Poly Phase Smart Meter datasheet (PDF).
