Efficiency achieved
08 June 2015
Ahead of Ecodesign standard EN 50598-2 NORD Drivesystems is performing tests and numerical analyses for components and systems manufactured in-house and can therefore quickly provide detailed information to resolve any customer queries concerning the standard.
The standard defines efficiency classes for frequency inverters and motor starters: IE0 (high losses), IE1 (reference values), and IE2 (losses significantly below reference).
Current tests with NORD inverters have shown power losses significantly below the reference values in the EN 50598-2 standard both for the inverters themselves and for power drive systems (PDS) combining inverters and energy-efficient motors. Consequentially, NORD is always able to achieve an IES2 system efficiency rating.
