How does this affect variable frequency drives?
The latest Ecodesign Directive introduces International Efficiency (IE) classes for certain variable frequency drives. From 1st July 2021, specified VFDs must meet IE2 specification. Our HP Combi drive range already meet these requirements.
New requirements for drive support information.
From 1st July 2021, support information for every drive covered by this directive must include its IE class and year of manufacture. VFD manufacturers must also provide power losses in terms of 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 three-phase standard drives with a diode rectifier in the range 0,12 kW ≤ Pn < 1000 kW. After 1st July 2021, the power losses of these drives shall not exceed the maximum power losses corresponding to the IE2 efficiency level. The efficiency level is given at the nominal point.
HP Combi drive range by Lafert is built to exceed the requirements of IE2 as required by the Ecodesign Directive.
