New auxiliary power supply units for Amsterdam metro

In order to keep the Amsterdam Metro trains (type S3/M4 from CAF, APU builder Transtechnik) running, the operator GVB was in urgent need of a company that could replace the aging and failing GTO based APU’s. Strukton designed a from-fit-function replacement for the customer using our standard IGBT based modulear technology.
