摘要

Transformers and DC power supplies are specified in the relevant standards. These include DIN VDE 0550, DIN VDE 0551 (EN 60742), DIN VDE 0570 (EN 61558) and DIN 19240. In practice, the actual demands extend beyond the specifications in the various Standards, especially when manufacturing woodworking machines.
