简要说明：SIRIUS — 适合各种应用的理想软起动器 目前，三相电机通常作为用户最终选择的驱动形式。但在很多情况下， 直接起动或星三角起动等传统起动方式会引起机械冲击、电网电压骤降 等问题

　　西门子软起动器SIRIUS 3RW40
SIRIUS 3RW40是西门子SIRIUS软起动器的新成员其创新的控制技术，使之至今仍是世界上唯一能够在250kW、400V功率范围内两 相控制的软起动器。是世界上最小的软起动器。因此可保证节省空间，使控制柜排布清晰。是两相控制的SIRIUS 3RW30/31系列软起动器的姊妹产品。SIRIUS 3RW40采用拥有专利权的全新控制技术－“相位平衡”。该控制技术能够防止两项控制软起动器中的直流成分。对于两相控制软起动器 ，来自两个控制相位的电流会流经未受控制的相位。SIRIUS 3RW40标准配备有最佳的功能。具有集成状态显示和故障监控功能。
