Carlo Gavazzi expands its Quick Fit range with EM271
Speeding up the retro fit market with faster installation times

Frimley, UK, 10th September 2014– Carlo Gavazzi shows its latest EM271 energy meter and miniature split core current sensors complete with umbilical cable at the Energy Event 2014 on stand No. A20.  A dramatic speedup of installation time is achieved when compared to existing methods thanks to its innovative features which allow a 3 phase energy meter and its current transformers to be installed 5-10 times faster.

EM271 is part of the favoured EM270 family of quick fit energy meters.  Similar to the EM270 it can measure up to two three phase loads or up to six single phase loads as well as creating a virtual meter to provide the sum of two three phase or six single phase loads.

Available as either Modbus + Pulse or Modbus + Modbus versions it provides fast and easy data transmission to PCs and PLCs for full load control, whilst all electrical parameters of the installation can be sent via the RS485 serial port for integration with BMS (Building Management Systems) and other standard acquisition-monitoring systems.

A choice of systems can be programmed providing active and reactive energy measurement and a selection of 3-phase or single
phase loads. Options include: system variables such as W, var, PF, Hz and phase-sequence; single-phase variables including A, VLL, VLN, PF; TRMS measurements with distorted sine waves; and energy measurements (total kWh and kvarh) for up to two 3-phase loads or 6 single phase loads. Voltage connection is achieved by detachable terminals allowing fast daisy chain of multiple meters.

Instantaneous variables are displayed as 3 x 3 digits, with energy meter readings to 6+1 digit resolution. Accuracy is ±0.75% RDG ( A) for complete meter and CT combination and the meter is rated equivalent to class 1 (kWh) according EN62053-21.

Operating temperature range is from -25°C to +55°C and the front panel offers IP50 protection against dust and water ingress.

The EM271 quick-fit meter is an offspring of the popular EM21 family of meters which are an innovative and cost-effective energy meter solution.  The patented self-powering detachable display enables the meter to be mounted either on a front panel with just 72x72mm footprint, or on a DIN-rail in only four modules wide.

Featuring three miniature split core current transformer (TCD series) specifically designed for the EM271 quick-fit meter comes complete with a 80cm pre-wired RJ11 connector; available in 60A, 100A, 200A and 400A with various cable lengths available up to two metres.  With a single click auto connection of the primary current of the external miniature split core sensors provide zero wiring errors and the meter is automatically programmed for CT ratio accuracy and calibration.

The EM271 quick-fit meter is especially suited to retrofit applications, switchgear or distribution panel manufacturers as well traditional panel builders.  It offers a simple to use metering solution and a popular choice to ensure optimal performance.

Carlo Gavazzi presents a full metering solution at the
Energy Event 2014 demonstrating a closer integration between metering and building management systems.

Carlo Gavazzi UK will attend the forthcoming Energy Event on 16-17th September 2014 at Birmingham’s NEC.  On show will be a complete range of MID certified energy meters for billing applications as well as VMUC-EM, the latest cloud based energy monitoring platform. 

Energy metering experts will also be available to give free advice on any aspects of energy metering or MID cost allocation application.
Energy Metering Family

Carlo Gavazzi’s extensive family of easy-to-install three phase energy meters now includes the EM270 which speeds up installation time dramatically when compared to existing methods thanks to its innovative features which allow a 3-phase energy meter and its current transformers to be installed 5-10 times faster ensuring error free connection.

A single EM270 quick-fit meter can measure all electrical variables and energy of two independent three phase loads or six independent single phase loads via its two RJ11 current inputs.  The detachable dual voltage terminal blocks allow daisy-chaining of up to 20 meters whilst the RS485 port provides a daisy chain solution to the serial bus.

Available as either Modbus + 2 x Pulse or Modbus + Modbus provide fast and easy data transmission to PCs and PLCs for full load control, whilst all electrical parameters of the installation can be sent via the RS485 port for integration with BMS (Building Management Systems) and other standard acquisition-monitoring systems.

Supporting the energy metering family is the latest cloud based energy platform VMUC-EM which makes multi-site energy metering much easier and more cost effective as it doesn’t require a license fee and brings together closer integration with Building Management Systems.

The VMUC-EM collects data from the energy meters as well as analogue, digital inputs and it can also switch outputs.  It then exposes the data to local networks and the internet by providing three Web services: a file transfer protocol (FTP) server, which enables data to be pushed to a capable BMS, server or cloud-based service provider on a scheduled basis; an HTTP client that allows data to be pulled on demand; and a Web server providing always-on access to real-time data, trending and alarms. 

Logged instantaneous variables of each meter can be displayed on daily, monthly or annual basis on an easy to read GUI; displaying the entire installations energy consumption.  This data can be acquired from either the main meter or a virtual meter, which is the sum of any pre-defined sub-meters, helping drive down costs; estimations can be made based on a dual tariff system which includes active and reactive energy costs, and any monthly penalties that may occur due to exceeding the contractual power allowance.  All data is easily exported in a csv format.

Established meters such as the popular EM21 meter with its unique detachable display and EM24 three-phase energy analyser with built-in joystick and LCD data displays active and reactive energy metering for cost allocation applications.
