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.
Six LED indicators display phase status, energy pulse signals, load direction, and RS485 communication status.
Automatic load current direction detection with dedicated LED indication for enhanced monitoring accuracy.
Supports active energy measurement and optional multi-parameter monitoring including voltage, current, power, frequency, and power factor.
Supports direct connection, CT connection, and PT & CT connection configurations.
Standard short terminal cover with optional extended terminal cover for improved protection.
Equipped with RS485 interface for remote meter reading and centralized energy management.
Supports DL/T645 and Modbus-RTU protocols for integration with energy monitoring systems.
