The ECBD005 series multifunction power meter is designed for advanced three-phase power monitoring, energy management, and electrical parameter analysis in commercial and industrial power distribution systems. Supporting high-accuracy energy measurement, harmonic analysis, demand monitoring, programmable DI/DO functions, and RS485 communication, the series is suitable for power quality monitoring, substation monitoring, energy management systems, and intelligent distribution applications.
Supports both MODBUS and DL/T645-2007 communication protocols with automatic protocol adaptation.
Class 0.5 active energy measurement and Class 1 reactive energy measurement for accurate power monitoring.
Equipped with RS485 communication interface supporting remote data collection and centralized monitoring.
Supports AC voltage input from 5V to 500V for various three-phase monitoring applications.
Supports AC current input from 20mA to 5A with overload capability for industrial power systems.
Standard energy pulse output with pulse constant of 8000 imp/kWh for energy monitoring integration.
Supports programmable remote control and alarm digital output with configurable alarm thresholds.
Supports passive dry contact digital input for remote telemetry switch status monitoring.
Selected models support demand display and harmonic analysis functions.
Stud-type current terminal design helps prevent loosening and reduces overheating risk caused by poor contact.
