Supports 1-phase 2-wire or 3-phase 3/4-wire systems.
High accuracy class 0.2S for active energy.
Graphical color display with customizable screens.
Memory for minimum and maximum values and archiving of up to 32 parameters.
Configurable alarm outputs and supervisory relay mode.
Analog output for retransmission and two Pt100 inputs for temperature measurement.
Ethernet interface with support for multiple protocols and services.

Measurement Capabilities:

Phase-to-phase and phase voltages, phase currents, and power factors.
Active, reactive, and apparent power and energy measurements.
Total harmonic distortion and individual harmonics up to the 51st order.
Temperature measurement with Pt100 inputs.

Communication and Interface:

RS-485 with Modbus RTU protocol.
Ethernet with Modbus TCP, HTTP, FTP, MQTT, and BACnet/IP protocols.
Web and FTP server capabilities for remote data access.

Technical Data:

Input types include Pt100 for temperature and current/voltage transformers.
