Devtech 3 Phase Coupler

Devtech 3 Phase Coupler is specifically designed for the Gateway products (IoT 5101/5104) which uses power line communication (PLC) mesh technology. It is used for coupling AC mains with PLC data lines (PLT + and PLT -). This can also be used for connecting AC mains signals between mutually different 3 phases (R, Y, B) in the PLC environment and especially optimized to be used in the LonWorks® power line communication. It is an important infrastructure component intended to use for all commercial PLC network applications especially for Street light management systems.

Features

  • Acts as a bridge between AC Mains and PLC Data lines ( PLT + and PLT -).
  • Attenuates large AC Mains signals ( 50 ~ 60Hz) while passing high frequency PLC communication signals.
  • Galvanic safety isolation between AC Mains and PLT+ & – terminals
  • Supports Line-to- Neutral Coupling.
