The European Union (EU) Ecodesign Directive focuses on making sure we get the maximum possible performance from the energy we use. The directive offers EU-wide uniform rules for improving the environmental performance of products, from household appliances to technical products.
The EU has set targets for energy efficiency and CO2 emissions to help limit the average global temperature rise to 1.5°C. To support this goal, the latest Ecodesign Regulation (EU) 2019/1781 came into force in October 2019 and now includes variable frequency drives (VFDs) and a wider range of motors. A second phase, which extends the scope of the regulation and increases the requirements for engines, will start on July 1, 2023.
How does this affect frequency inverters?
The latest ecodesign directive introduces international efficiency classes (IE) for certain variable frequency drives. Beginning July 1, 2021, certain VFDs must meet the IE2 specification. Optidrive AC drives already meet these requirements.
New requirements for drive support information
From July 1st, support information for any drive covered by this directive must include the IE class and year of manufacture. VFD manufacturers must also report power losses as a percentage of rated apparent output power at eight different operating points, as well as standby losses and apparent percentage power loss at various operating points.
What does IE2 mean for VFDs?
The regulation covers 3-phase standard drives with diode rectifiers in the range of 0.12 kW ≤ Pn < 1000 kW. After July 1, 2021, the power loss of these drives must not exceed the maximum power loss corresponding to efficiency IE2. The efficiency is specified at the nominal point.
Invertek Drives AC drives are all built to exceed the requirements of IE2 under the Ecodesign Directive.
