Silverteam ups power of its variable-speed drives

摘要

Silverteam has launched high-power versions - 160kW to 400kW - of the Hitachi SJ700 variable-speed drive. The SJ700 is the first off-the-shelf unit with integral easy sequence programmable functionality (EzSQ) as standard. The SJ700 is compact and incorporates a power-switching technology to reduce dVdT, with the IGBT (insulated gate bipolar transistor) stack at the heart of the drive.
