Overview

  • About Power Quality Meter EPM 7000

EPM 7000 power meters are conceptualized to revolutionize the traditional power quality metering industrial. Each power quality meter is a compact, electronically advanced and programmable multi-display metering device (MDMD). It is the solution to the next electrical generation.

  • PLC Modbus(R) Compatible

The Modbus(R) communications protocol allows information and data to be efficiently transferred between EPM 7000 and Modicon programmable logic controller (PLC) or other third party Modbus(R) compatible monitoring and control systems. The EPM 7000 can also establish a monitoring system by just simply adopting an IPC-based centralized master display software. The RTU mode Modbus(R) protocol with default to baud rate 9600 bps, 8 data bit.

  • Increase Productivity & Efficiency

The power meters are specifically designed to be compatible with the most widely used DIN standard panel with DIN 92 * 92mm panel cutout holes. It is also a standardize hardware suitable for various wiring set ups including 1 phase 2 wires, 1 phase 3 wires, 3 phase 3 wires or 3 phase 4 wires networks.

  • Improved Technical Superiority and Reliability

These power quality meters are endowed with technical specifications (overload capabilities, accuracy levels, long term stability, readout dependability etc.) far exceeding conventional instruments. Furthermore, the software provides a simple yet practical solution to energy management in factories and plants, small industries, building services, etc.

  • Factory & Building Automation ( FA & BA )

The EPM 7000 was developed for factory and building automation (FA & BA) applications. The EPM 7000 allows more power and energy parameters to easily be applied to a wide range of AC switch-gear or power distribution system for metering.

  • Field Programmability

This field programmable power quality meter is able to set e.g. CT and PT ration, Modbus(R) address, communication baud rate, meter's display, etc. either through rear RS-485 communication port or a maintenance port on the front panel with a communication module RX-024 specifically produced by HCE.

  • Comprehensive System Integration

With PLC compatible RS-485 / RS-232 (Option) Modbus(R) communication protocol, the 7000 series allows information and data to be efficiently transferred between power quality meter EPM 7000 RTU, Power SCADA system, DCS system.
