Features & Advantages

feature

Compact 1-Module Design

With an 18mm width, SEM1340 saves installation space and is suitable for compact meter boxes and distribution boards.

Bi-directional Energy Measurement

Measures import and export active energy, making it suitable for systems where power flow may occur in both directions.

WiFi & RS485 Communication

Supports wireless WiFi communication and RS485 Modbus, allowing flexible local or remote data access for monitoring systems.

Multi-parameter Monitoring

Measures voltage, current, active power, reactive power, apparent power, power factor, frequency, and energy data for complete single-phase circuit visibility.

CT Input Installation

Uses a 330mV CT input for current measurement, helping simplify installation in retrofit and space-limited applications.
