What does IE2 mean for VFDs?

Motor and fan related questions


The Ecodesign regulation EU 2019/1781 covers 3-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 International Efficiency level (IE) is given at the nominal point. After 1st July 2021, drives covered by the regulation must be IE2 compliant as a minimum in order to be CE marked.

Single-phase drives and fan speed controllers are excluded from this regulation.
