ACREL Multifunction Three Phase Power Meter
ACREL Multifunction Three Phase Power Meter is a multifunction three-phase AC power meter for monitoring electrical parameters, energy consumption and power quality. It measures voltage, current, active, reactive and apparent power, while providing harmonic analysis, demand measurement, event recording and communication functions. The meter supports RS485 Modbus RTU communication as standard, with optional digital I/O, analogue outputs, additional RS485 and Ethernet communication depending on configuration.
The ACREL Multifunction Three Phase Power Meter is designed for applications requiring more than basic voltage, current and energy measurement. It combines electrical measurement with power quality analysis, event logging and network communication in a multifunction meter.
The meter can monitor three-phase electrical parameters and provide information such as active, reactive and apparent power, power factor, frequency, energy and demand. It also provides power quality information including voltage and current unbalance, phase angles, waveform information and harmonic content up to the 63rd harmonic.
The ACREL Multifunction Three Phase Power Meter supports RS485 communication using Modbus RTU, making it suitable for connection to power monitoring and energy management systems. Optional configurations can add digital inputs and outputs, 4-20 mA analogue outputs, a second RS485 interface and Ethernet communication with Modbus TCP and FTP protocols.
How it works
- The meter measures voltage and current within a three-phase AC electrical system.
- It calculates electrical parameters including active, reactive and apparent power.
- Energy and demand information can be monitored, including maximum demand with timestamps.
- Power quality functions provide information on voltage and current unbalance, phase relationships, waveform characteristics and harmonics.
- Electrical data can be communicated through the RS485 Modbus RTU interface, with additional communication options available according to the selected configuration.
