TDK-Lambda is aiming at large industrial distributed power systems with a 45kW non-isolated ac-dc PSU. Called TPF45000-385 it can operate from can operate from 360 – 528Vac three-phase (delta or Y) and produces a stable 385Vdc. Input to ground isolation is 2kVac. Efficiency is up to 98%, allowing air cooling by internal variable speed fans. Operation is across -10 ...
