VLT® Lift Drive LD 302

  • Luotettava toiminta ja erinomainen käyttömukavuus

    VLT® Lift Drive on suunniteltu toimimaan luotettavasti ja parantamaan hissin käyttömukavuutta vähintään 2,1 miljoonan käyttökerran ajan, kun ympäristön lämpötila on alle 45 °C. Erinomainen uusissa projekteissa tai jälkiasennuksissa. Toimii ilman moottorikontaktoreja ja voidaan ottaa käyttöön nopeasti ja helposti alle 10 minuutissa.

    Sopii kaikille moottoreille, mukaan lukien asynkroniset, induktiomoottorit, kestomagneettimoottorit, kupariroottorit ja suorat online-PM-moottorit. VLT Lift Drive soveltuu sekä veto- että hydraulihisseihin, joissa käytetään joko takaisinkytkemätöntä (open loop) tai takaisinkytkettyä (closed loop) säätöä.

    Kompaktin rakenteensa ja älykkään jäähdytyskonseptinsa ansiosta se sopii ahtaisiinkin asennuspaikkoihin. Sisäänrakennettujen toimintojen ansiosta ylimääräisiä komponentteja ei tarvita. Skaalattavat RFI-suodattimet vähentävät sähkömagneettisia häiriöitä ja integroidut tasavirtakuristimet suodattavat harmonista säröä sekä varmistavat, että taajuusmuuttajat täyttävät asianmukaiset EMC-standardit eikä jännitteennosto- tai -laskumuuntajia tarvita.

    380–400 V...4–55 kW

    Ominaisuudet ja edut

    • Hissimatkojen mukavuus paranee melua vähentävien toimintojen ansiosta
    • Energiaa säästyy, kun jäähdytyspuhaltimia käytetään vain silloin, kun se on välttämätöntä
    • Taajuusmuuttaja on nopea ja helppo ottaa käyttöön, sillä se sopii kaikkiin yleisiin järjestelmiin, joissa on takaisinkytkentä, ja määritettäviä parametreja on vain 10
    • Taajuusmuuttaja toimii luotettavasti vaativissakin olosuhteissa erikoislakattujen piirilevyjen ansiosta
    • Jämäkän rakenteen ansiosta komponentit pysyvät tiukasti paikoillaan myös ympäristöissä, joissa on paljon tärinää

    Käyttökohteet

    Korkeahkojen ja korkeiden asuin- ja liikerakennusten hissit, teollisuuskohteiden rahtihissit, kaivoskuiluhissit, vapaa-ajankohteiden hissit, kuten hiihtohissit, venehissit, lentokonehissit, ajoneuvohissit, liukukäytävät.
