The ECBD009 three-phase multi-circuit energy meter is designed for centralized multi-loop energy monitoring, prepaid billing, and intelligent power management in apartments, dormitories, commercial buildings, and tenant sub-metering applications. Its modular DIN rail architecture allows a single communication and display module to manage multiple metering modules, helping reduce installation space, simplify maintenance, and improve deployment efficiency for high-density energy monitoring systems.
One communication and display module supports up to 12 metering control modules for monitoring up to 36 single-phase circuits or 12 three-phase circuits.
Communication and display modules are separated from metering control modules for easier maintenance and partial module replacement.
Supports RS485 and LoRa communication methods with shared communication and display modules.
DIN rail mounting structure with standard RJ45 bus ports for fast modular installation and assembly.
Supports prepaid metering, user energy billing, arrears management, and multiple payment methods.
Supports scheduled power disconnection, overload protection disconnection, forced power-off control, and arrears cut-off functions.
Main and sub-modules support configurable DI and DO interfaces for monitoring and control applications.
Equipped with RS485 and infrared communication interfaces supporting DL/T645-2007 protocol.
