Siemens zaus hloov pauv, nrog rau lawv cov txiaj ntsig muaj zog, tau rhuav tshem yav dhau los monopoly ntawm Japanese hom hauv Suav lag luam. Raws li kev txheeb cais los ntawm cov koom haum tshawb fawb kev lag luam, Siemens 'siab thiab qis voltage zaus converters tam sim no nyob rau hauv lub lag luam Suav.
Siemens zaus converters tau siv thawj zaug hauv kev lag luam steel hauv Suav teb. Txawm li cas los xij, nyob rau lub sijhawm ntawd, kev tswj xyuas lub cev muaj zog tseem yog raws li DC ceev tswj, thiab daim ntawv thov ntawm cov zaus hloov pauv tseem yog kev lag luam tawm tshiab. Tab sis nrog kev txhim kho txuas ntxiv ntawm cov khoom siv hluav taws xob thiab kev loj hlob ntawm kev tswj txoj kev xav, zaus hloov pauv ceev tswj tau maj mam hloov DC ceev tswj thiab dhau los ua lub ntsiab ntawm cov khoom siv tsav. Siemens zaus converters tau ua tiav qhov kev loj hlob txawv tshaj plaw hauv Suav lag luam loj no vim lawv cov khoom lag luam muaj zog. Siemens 'kev vam meej nyob rau hauv Suav teb zaus converter lag luam tuaj yeem raug ntaus nqi los ntawm kev sib xyaw zoo tshaj plaws ntawm Siemens hom thiab thev naus laus zis. Thaum ntxov Siemens zaus converters ntsib nyob rau hauv Suav lag luam feem ntau suav nrog tam sim no-qhov chaw SIMOVERT A thiab qhov hluav taws xob-qhov SIMOVERT P. Cov converters no nkag mus rau Suav lag luam feem ntau vim yog cov khoom siv tshiab thiab tseem siv tsawg. Tom qab ntawd, MICRO MASTER thiab MIDI MASTER series, nrog rau Siemens 'zoo tshaj plaws series, SIMOVERT MASTERDRIVE (feem ntau hu ua 6SE70 series), tau muag ntau hauv Suav teb. Cov koob no tsis yog tsuas yog muab AC zaus hloov pauv rau cov ntawv thov dav dav tab sis kuj tseem muaj DC cov kev daws teeb meem rau ntau lub cev muaj zog hauv kev lag luam tshwj xeeb xws li papermaking thiab tshuaj fibers. Siemens kuj tau pib ECO zaus converter, uas kuv tus kheej xav txog kev ua tsis tiav tab sis kev ua lag luam ua tiav. Nws cov kev tsis ua haujlwm tau tshwm sim los ntawm nws qhov tsis ua haujlwm siab, thaum nws txoj kev lag luam ua tiav tau zoo heev vim dhau Fuji zaus hloov pauv los ua lub hom lag luam hauv Suav lag luam. Siemens 'cov qauv tseem ceeb hauv Suav lag luam yog MM420, MM440, thiab 6SE70 series.
