ELTA PUBLISHES NO-NONSENSE GUIDE TO ERP LEGISLATION
E
lta Fans has published a comprehensive and easy-to- understand 48-page document entitled “How fans are affected by the ErP Directive.” The Directive was implemented in EU member countries by the European Parliament, on November 20, 2010 and adopts the European Commission's (EC) proposal to widen the scope of the Eco- design Directive 2005/32/EC to include energy-related products. The aim of the Elta Fans’ document is to offer a straightforward, no-nonsense guide for potential purchasers to understand the implications of the new legislation, now and in the future. Alan Macklin, Technical Manager of the Elta Group, says: “The introduction of mandatory, energy-efficiency legislation is the biggest issue the fan industry has ever faced. Despite its importance, there is still a lack of understanding in many quarters and this document is designed to help dispel the confusion, to cut through the complexity of the legislation and to spell out simply what it means for the industry. I urge anybody involved in specifying fans to get a copy as ignoring or not understanding the legislation is not an option.”
The enormous explosion in global population density and the resultant worldwide shortage in energy, requires reductions in energy consumption throughout the entire life cycle of the fan. The Directive is intended to help in delivering European Union (EU) objectives to reduce greenhouse gas emissions, to reduce the adverse environmental impacts of product manufacture and to ensure free trade in energy-using and energy-related products. It goes beyond simple efficiency of energy usage into the entire product- lifecycle and accounts for total lifecycle cost, monitoring efficiency from the mining of raw material right through to end-of-life recycling. The first phase of the new directive becomes mandatory in January 2013 – with the second phase of legislation coming into effect two years later, at the start of 2015.
The significance of the new ErP regulations is that manufacturers such as Elta Fans are now required to review their product range in order to attain new efficiency levels. Inefficient fans are being taken out of production by legislation, in the same way that inefficient, old-style light bulbs are being phased out for energy-efficient ‘compact fluorescent
Carlo Gavazzi launches MID-compliant Energy Meters
C
arlo Gavazzi has updated its popular family of easy-to-install DIN three phase energy meters to meet the requirements of the Measuring Instruments Directive (MID). The EM23- DIN energy meter and EM24-DIN energy analyser are available with immediate effect and will be closely followed by the EM21 meter with detachable display and
EM26 meter with pulse output and MODBUS. Suited to both active and reactive energy metering and cost allocation, the meters are ideal for use in smart building and building automation applications.
The self-powered EM23 energy meter offers direct three-phase connection up to 65A and is now available with 2V or 9V rating and an autorange function up to 1kWh. Just four DIN modules wide, the meter requires no programming and simple configuration is achieved via a built in joy stick. An LCD display shows both active and reactive measurements and a pulse output is provided for easy transmission of energy values to PLCs. The meter is mounted in an IP50 housing (front face) to protect against dust and moisture ingress. Featuring a built in joystick and LCD display, the EM24 three-phase Energy

Analyser has two digital outputs for either dual pulse, dual alarm or one pulse/one alarm, and the pulse output duration can be set at Ton of 30 or 100ms. Alternative input options are for a RS485 communication port or Dupline port, both with three digital inputs for connection to up to three energy meters such as gas, hot/cold water or kWh. In addition, the prescaler decimal point can be selected by the user from 0.001 to 999.9 (m3 kWh/pulse).

The EM24 is now available with full integrated power for easy installation or just positive power integration, and the CT ratio can be selected when switched on for the first time. When used in conjunction with the VMU-B RS485 to M-BUS converter, EM24 outputs can be read by a secondary address programmed at the calibration stage.

lamps’ (CFLs) as part of the EU’s eco- design for energy-saving products regulations.
The European Commission has not yet come up with a definitive product list, but ‘energy-related’ products are defined as: “goods having an impact on energy consumption during use". This includes not only all energy-using products, but also energy-saving products. The Elta Fans 48-page explanatory document can be viewed at
