Modbus RS485 and Power Quality Measurement

The METSEPM5110 integrates electrical parameter acquisition with RS485 serial communication using Modbus RTU and ASCII protocols. The measurement engine samples electrical waveforms at 64 samples per cycle and records voltage, current, frequency, power factor, active and reactive power, and energy values. Harmonic analysis supports measurement up to the 15th harmonic for power quality evaluation.

The meter supports single-phase and three-phase network configurations with current transformer inputs rated at 1 A or 5 A. The RS485 communication port provides two-wire data transmission with configurable baud rates and supports remote monitoring through Modbus-based control systems.

Field Installation Guidelines

Install the METSEPM5110 in a suitable flush-mount panel opening with correct terminal assignment for voltage circuits, current transformer inputs, control circuits, digital output circuits, and RS485 communication wiring.

Use shielded twisted-pair cable for RS485 communication where required by the installation environment. Connect cable shields according to the site grounding practice to reduce electromagnetic interference. Keep communication wiring separated from high-current power conductors to minimize electrical noise coupling.

Verify the phase sequence, current transformer polarity, rated voltage range, and network configuration before energizing the meter. Confirm Modbus addressing, baud rate, and communication parameters before integrating the device into a monitoring network.
