Anywire / Breitband Power Line Communication (PLC) Repeater

Description

The broadband PLC repeater is used in transformer stations or in distribution cabinets. When the PLC repeater is used in the distribution cabinet, it is exposed to high temperature fluctuations and moisture. Therefore, the PLC repeater must withstand adverse environmental conditions. Since no personal protection by means of an RCD is guaranteed in transformer stations and distribution cabinets, the Ethernet interface must be separated from the mains side by means of reinforced insulation. With this product, the voltage regulator was optimised so that the lowest possible switching emissions can return to the grid via the mains line. This enables the use of all available PLC carriers for maximum power line data throughput. Overview of commissioned services
