The energy management system for the utility

EMU Electronic provides total solutions for measuring, monitoring and reporting electrical energy and other energy flows such as gas, water and heat.

kWh meters with many types of bus systems 

The measuring instruments can be equipped with a variety of bus systems such as M-Bus, Modbus, KNX, Modbus TCP and BACnet IP. This makes the meters easy to integrate into different types of building management systems. With the M-Bus datalogger it is possible to store, visualize and link the data of different M-Bus kWh meters via Bacnet IP or OPC UA. With Joulio web (software) the systems are complemented and the energy flows can be monitored via a Web-based interface both locally and in the cloud.

Due to the simple installation and configuration, the EMU Electronic systems are ideal for any installer who wants to offer a total solution for energy monitoring in, for example, schools
, utilities, office buildings and apartment complexes.

Systeemopbouw van EMS van EMU

EMU Allrounder kWh meter

3-phase energy and power meter

The EMU Allrounder is a 3-phase energy and power meter. The meter is MID B + D approved for energy management according to ISO 50001. The kWh meter is easy to configure via the buttons on the meter and can be used universally. The EMU Allrounder is perfectly suited for energy measurement and consumption measurement of several small groups and for building management systems.

Interface to read out the EMU Allrounder

The kWh meter is standard equipped with one pulse output and is optionally available with an M-Bus interface. The M-Bus interface is integrated into the hardware, which guarantees maximum reliability of the measurement data. Many different measured values such as active energy, active power, current, voltage and frequency are sent via the bus system.

User-friendly display

A large graphic display of 60 x 30 mm with LED backlighting makes it possible to read the measured values under all circumstances. The quantities, the description of the quantity, the direction of the energy and the rotating field can be read from one screen.

Features

  • Actual consumption measurement (kWh sum)
  • Direct measurement 75 A.
  • Indirect measurement / 5 and / 1 A (current transformers)
  • Accuracy class B (+/- 1%)
  • Double rate (day / night)
  • S0 pulse output (1x)
  • M-Bus interface (optional)
  • MID approved for billing purposes
  • Suitable for energy management ISO 50001

EMU Professional kWh meter

Universally applicable kWh meter

Like the EMU all-rounder, the EMU Professional is a universally applicable kWh meter and is optionally equipped with a TCP / IP, M-bus, Modbus, KNX or LON communication interface.

EMU Professional with TCP/IP connection

The top model of the EMU line is the EMU Professional with TCP / IP connection. This meter has a built-in web interface for visualizing the measurement data. A standard web browser on a PC, laptop, tablet, smartphone or touch panel PC is sufficient for the presentation and analysis of the measurement data.

Alarm systeem

The built-in alarm system warns you by e-mail or via an SMS gateway if a measured value exceeds a set limit value. Saving energy has never been easier!

User-friendly display

A large graphic display of 60 x 30 mm with LED backlighting makes it possible to read the measured values under all circumstances. The quantities, the description of the quantity, the direction of the energy and the rotating field can be read from one screen.

Features

  • Actual consumption measurement (kWh sum & per phase)
  • 4 quadrant measurement
  • Direct measurement 75 A.
  • Indirect measurement / 5 and / 1 A (current transformer)
  • Accuracy class B (+/- 1%)
  • Double rate (day / night)
  • S0 pulse output (4x)
  • Digital output and Web interface (optional)
  • TCP / IP, Modbus, M-Bus, KNX and LON interface (optional)
  • MID approved for billing purposes
  • Suitable for energy management ISO 50001

Datalogger/Gateway - EMU M-Bus Center

Datalogger

The EMU M-Bus Center is a data logger and is fully configurable using a user-friendly interface. The interface can be accessed with any usual web browser (HTML5). The graphic display shows the IP address that has been manually configured or obtained via a DHCP. The automated meter reading ensures continuous and error-free data collection and storage for subsequent analysis and billing according to ISO 50001. In addition, gas, water and heat meters can also be read.

M-Bus to BACnet IP Gateway

The M-Bus Center is an ideal system component for integration into a BACnet IP network. As soon as an M-Bus meter is registered or imported, it can be read directly via BACnet IP. The connected kWh meters are individually read in as a slave and recognized as a separate measuring instrument. Integration into a higher BACnet IP system does not require any configuration.

Plug & Play-communication with energy management and billing software

The M-bus loggers can be read in an overhead energy monitoring system. Drivers can optionally be added to communicate with other devices. All available measurement data is retrieved by the parent energy monitoring system (EMS) Joulio-Web. Using Joulio-Web, the measurement data can be visualized for energy management and billing purposes.

Features

  • M-Bus to TCP/IP, BACnet IP and OPC UA
  • M-Bus high performance level converter
  • Data expot as .CSV and .JSON and (s) FTP-upload
  • Automatic data storage in case of failed server connection
  • IoT & Industry 4.0 ready
  • Configuration, updates and backups via web server

Technical data EMU M-Bus center:

  • Supply voltage 24VDC, 1A
  • Expandable memory (16 or 32 GB Micro SD)
