Designed for reliable single-phase energy monitoring and remote meter reading, this DIN rail energy meter supports RS485 communication with optional NB-IoT and LoRa connectivity. Its compact structure, multiple current rating options, and remote connect/disconnect capability make it suitable for sub-metering, energy billing, and distributed energy management applications.
The meter features a 7-digit LCD display to indicate active energy consumption and is characterized by high reliability, compact size, light weight, attractive appearance, and easy installation. It is widely applicable and convenient for system integration and supporting applications.
Supports 35 mm DIN rail mounting compliant with DIN EN 50022 or optional front-panel mounting.
7-digit LCD display with standard 6+1 digit format and optional 5+2 digit configuration.
Standard passive energy pulse output with optional non-polarized remote pulse output for AMR integration.
Three LED indicators for power status, energy pulse signal, and RS485 communication status.
Optional automatic load current direction detection with dedicated LED indication.
Unidirectional measurement of single-phase two-wire active energy consumption compliant with IEC 62053-21.
Supports direct connection, CT connection, and PT & CT connection configurations.
Standard short terminal cover with optional extended terminal cover for improved safety protection.
Equipped with RS485 interface for remote meter reading and centralized energy management.
Optional MODBUS-RTU and DL/T645 communication protocols available for system integration.
