Two Major Communication Modules of Four-Faith Reach Directly to the Core of the Centralized DTU

The New Specification of the National Network Redefines the Industry Standard

In order to further deepen the standardization of distribution networks and improve the durability of equipment, the State Grid Corporation has organized and released a new specification "Standardized Design Plan for 12 KV First and Second Fusion Ring Main Unit (Boxes) and Distribution Automation Terminals (DTUs) (Version 2021)", which provides a standardized definition of the classification, appearance and interface of centralized DTU.

F-LC100 and F-RT100 communication modules of Four-Faith conform to industry standards with local and remote dual links support, meeting the needs of industry applications in all aspects.

Local and Remote Communication Modules Reach Directly to the Core of the Centralized DTU

The external remote communication module F-RT100 and the local communication module F-LC100 are installed on the centralized DTU core unit. The remote communication module connects to the distribution network dispatching master station through the operator's 2G/3G/4G network or the electric power company's own 1.8GHz private network, and realizes data interaction with the main dispatching station at the centralized DTU core; the local communication module F-LC100, on the other hand, uses LoRa 2.4GHz and 470MHz to provide wireless short-range small data transmission function for users.
