Radical development sets benchmark for large drives

Radical development sets benchmark for large drives
Silverteam is launching high power versions - 160kW to 400kW - of the Hitachi SJ700 variable speed drive, adding to the small and medium sized versions introduced in 2007. The company claims the SJ700 represents a radical development of drives technology, it being the first off-the-shelf unit with integral easy sequence programmable functionality (EzSQ) as standard.

Perhaps the first notable thing about the SJ700 is its compact size - an increasingly important issue as users and systems builders seek to reduce control panel size. It also incorporates a patented power switching technology to reduce dVdT, with the IGBT stack at the heart of the drive. High dVdT is associated to motor insulation breakdown by the increased terminal voltage of motors when used with AC drives.
