Major Changes in the New Standard1Expanded Scope of Application
Scope of the old-edition standard: Power electronic converter systems (PECS), any specified accessories and their components for electronic power conversion and electronic power switching, including means for control, protection, monitoring and measurement. It applies to equipment primarily intended for power conversion with a rated system voltage not exceeding 1 000 V AC or 1 500 V DC.
It also serves as a reference standard for the following products:
Power drive systems (PDS);
Stand-alone uninterruptible power supply (UPS);
Low-voltage stabilized DC power supplies;
Bidirectional converters.
