Three-phase AC drive AS700

vector controlfloor-standingfor industrial applications

AS700 High Power Multi Drives is designed and developed for industrial applications of DC multi-drive inverter, mainly used in lifting industry, such as large gantry crane, quayside bridge, bulk crane. Also used in paper, metallurgy, mining, cement, energy, petrochemical and natural gas industries. The product adopts advanced vector control technology and torque control technology, combined with the crane industry application characteristics, strengthened the reliability of the product and the adaptability of the environment as well as the customer design, can better meet the needs of a variety of transmission applications. · Multi-drive, big power · Work for both two quadrant and four quadrant operation · Used for large lifting, steel rolling and mining belt equipment Can offer two modes including SCR rectifier and AFE active rectifier according to the user demand. AFE  · A bidirectional (returnable) rectifier in a common dc bus system； · Composed of power unit +LCL filter； · AFE need additional pre-charge circuit； · AFE can be parallel to each other, and no special connector is required； · Suitable for applications requiring low harmonic and energy feedback SCR · Unidirectional (electrically directed) rectifying device in a common dc bus system； · The input side is equipped with a special reactor and the support units are in parallel； · SCR rectifier units do not require an external charging circuit； · The SCR rectifier unit can charge the dc bus, which is suitable for the occasions where there is no higher requirement for harmonic quantity and no energy feedback
