The ECBD001 DIN-rail mounted single-phase electronic energy meter is newly developed using advanced microelectronics technology, dedicated large-scale integrated circuits (LSI), digital sampling processing technology, and SMT manufacturing processes.
The meter fully complies with the IEC 62053-21 Class 1 standard for single-phase energy meters and is designed to accurately measure the active energy consumption of loads in single-phase two-wire AC power systems with a rated frequency of 50 Hz or 60 Hz.
The meter features a 7-digit LCD display for active energy consumption and offers high reliability, compact size, lightweight structure, attractive appearance, and easy installation, making it suitable for a wide range of electrical measurement and monitoring applications.
Supports 35 mm DIN rail mounting compliant with DIN EN 50022, or front-panel mounting. Users can select either installation method.
7-digit LCD display with standard 6+1 digit format (999999.9 kWh). Optional 5+2 digit display format available.
Standard passive energy pulse output (polarized). Optional passive remote pulse output (non-polarized), compliant with IEC 62053-31 and DIN 43864.
Three LED indicators for power status, energy pulse signal, and RS485 communication status.
Standard version does not detect load current direction. Optional automatic current direction detection with dedicated LED indication.
Unidirectional measurement of single-phase two-wire active energy consumption, compliant with IEC 62053-21.
Standard S-type direct connection wiring (bottom input, top output). Optional CT or PT & CT connection configurations available.
Standard short terminal cover with optional extended terminal cover for enhanced electrical safety.
Equipped with RS485 communication interface for remote meter reading and centralized energy management.
Standard communication protocol included. Optional MODBUS-RTU or DL/T645 protocols available.
