Product Description

Application

The multi-functional monitor and control meter is a high-performance intelligent instrument. It measures power parameters and harmonic waves in real-time, including positive and negative active/reactive energy. It analyzes electric quality, displays real-time waves, and records events and demands. Integrated with RS-485 ports, it supports various intelligent distribution systems. It is widely used in energy management systems, power monitoring, industrial facilities, and smart buildings.

Performance Characteristics

High precision measurement of three-phase voltage, power, factor, and frequency.
Forward and reverse active/reactive energy measurement.
Time-sharing / power timing meter reading capabilities.
Measurement of THD (Total Harmonic Distortion) and 2-31 odd harmonic components.
Nixie tube or liquid crystal display options with local data query.
Programmable current and voltage gain.
Supports multiple circuit leakage monitoring and loop control nodes.
Remote cut-off support for fault circuits via fire control signals.
RS-485 communication with Modbus-RTU protocol.
AC/DC 80V-270V wide-range power supply.
