PowerFlex 7000使用6.5KV 800A/1500A的对称门极换流晶闸管(SGCT)，变频所用逆变开关器件数量比其他任何中压变频技术的器件数量都少。功率结构为无熔断器，具有电流抑制DC电抗器。其结果是更简单，牢固，可靠之产品。
PowerFlex 7000具有免传感器的直接矢量控制。免传感器的直接矢量控制对马达的磁通是测算而不是估算。如同直流驱动，马达力矩可快速改变而不影响马达磁通。此控制方式可产生较标准V/Hz型变频更优越的运行性能。对持续运行在6Hz以下的低速应用，可选用带测速反馈的完全矢量控制 PowerFlex 4系列变频器是适用于机器级独立控制应用或简单系统集成的简便、高性价比解决方案。这一通用型系列变频器本着易于使用的设计宗旨，可提供
紧凑的封装以优化面板空间和应用的多功能性。
PowerFlex 7系列变频器功能丰富、针对具体应用的参数众多，非常适合于高性能应用场合。该系列变频器专为实现高级应用的灵活性和控制系统的集成而设计。
aintenance faster, more economical and more efficient.
Industrial” is a world-leading all-round integrated open control system launched by ABB Group Automation Headquarters.
It integrates the advantages of traditional DCS and PLC in one body and supports a variety of international field bus standards. It has both the complex analog loop regulation capability of DCS
Power-friendly human-machine interface (HMI) and convenient engineering software, and at the same time have high-speed logic and sequence control equivalent to high-end PLC indicators.
control performance. The system can be connected to both conventional I/0 and various field bus devices such as Profibus, FF, CAN, and Modbus. system tool
It has a high degree of flexibility and excellent scalability, whether it is the control of small production units, or the control of ultra-large-scale whole plants – integrated control, even
The Industrial” system can handle the application of field equipment maintenance management and cross-plant production management control with ease.
An important member of the Industrial” family, the AC800F system fully embodies the Industrial” (Industrial Information) system pioneered and led by ABB in technology.
