VACON® NXP Common DC Bus

  • Helppo integrointi – erinomainen joustavuus

    VACON® NXP Common DC Bus -tuoteperhe sisältää syöttöyksiköitä (Active Front End), invertteriyksiköitä ja jarrukatkojia. Ne varmistavat energian tehokkaan hyödyntämisen ja takaisinsyötön verkkoon.

    Common DC Bus -yksiköitä voidaan käyttää monipuolisesti erilaisissa yhdistelmissä. Regeneratiivisessa DC-väyläjärjestelmässä Active Front End -yksiköt syöttävät tehoa takaisin verkkoon. Tämä sopii prosesseihin, joissa jarrutusta tarvitaan usein ja jarrutusteho on melko suuri. Ei-regeneratiivisessa järjestelmässä jarrutusteho syötetään takaisin järjestelmän muille taajuusmuuttajille, ja mahdollinen ylimääräinen teho voidaan haihduttaa lämpönä hyödyntämällä lisävarusteina saatavia jarrukatkojia ja jarruvastuksia. Tämä soveltuu erinomaisesti pienille tuotantolinjoille, joissa jarrutusta tarvitaan harvemmin.

    3 x 525690 V...32 000 kW

    Ominaisuudet ja edut

    • Energiakustannukset pienenevät, koska regeneratiivinen yksikkö syöttää ylimääräisen jarrutusenergian takaisin verkkoon 
    • Investointikustannukset pysyvät alhaisina, koska verkkokaapeleita tarvitaan vähemmän ja asennusaika on lyhyempi
    • Kustannuksissa ja tilankäytössä saadaan säästöä, koska optimoitu moduulirakenne vähentää lisäsuunnittelun ja kotelotilan tarvetta
    • Viisi sisäänrakennettua laajennuspaikkaa I/O-lisäliitännöille, kenttäväylille ja toiminnallista turvallisuutta lisääville korteille helpottavat suunnittelua ja mahdollistavat yksinkertaisemman järjestelmän.
    • Active Front End -yksikkö parantaa järjestelmän sietoa jännitelaskua ja jännitteen harmonisen särön vaikutusta vastaan
    • Kompaktien lisäkorttien helppo asennus

    Käyttökohteet
