Rockwell Automation has extended the ratings of its Allen-Bradley PowerFlex 755 AC drives to 1500 kW/2,000 Hp, completing the power range of the PowerFlex 750-Series portfolio and providing customers with a wide selection of options and features. The high-power drive builds on the application flexibility and common user experience of the PowerFlex 750-Series, giving heavy industries a new option for advanced power control.
The PowerFlex 755 drive is well suited for a wide variety of applications ranging from simple variable speed and variable torque control to the most demanding systems requiring constant torque control. Target applications include fans, pumps, mixers, compressors, conveyors and extruders, as well as applications for the oil and gas, tire and rubber, refining, metals and mining industries.
“We designed the PowerFlex 755 drives with ease-of-use in mind, and expanded its power range to deliver this user experience to a wider range of applications,” said John Cherney, global product manager, Rockwell Automation. “Whether an application demands one or 2,000 horsepower, the way users interface with any PowerFlex 755 frame is nearly identical. This commonality helps to simplify operation, from configuration and integration to maintenance and troubleshooting.”
最新的帧扩展可提供早期的高功率模型的增强控制功能，包括特征，例如400/480/600/690伏特级和N-1技术。使用N-1技术，用户可以配置PowerFlex 755高功率驱动器，以利用其一个，两个或所有电源结构。这为有效地管理负载变化，保护设备，并在电源故障时保持驱动器和运行，这提供了冗余和高级控制。公共DC总线选项允许用户将PowerFlex 755 AC驱动器连接到DC总线配置，这利用不同的驱动循环来共享能量。使用普通的直流总线系统有助于提高系统性能并减少损耗 - 最终提高应用的能效。
与所有PowerFlex 755驱动器一样，最新的帧大小包括嵌入式以太网端口和多个选项插槽，因此用户可以根据其应用程序定制驱动器。选件模块包括I / O，反馈，安全性，额外的通信和辅助电源。此外，方便的卷展栏设计允许轻松进入驱动器以进行快速安装和维护。当逆变器推出时，驱动器的转换器和控制吊舱可以保留在本机中，因此控制接线可以保持完整。驱动器适用于独立应用，并具有实时时钟，可提供数据记录和增强的诊断。
The power-range extension is one of several enhancements to the PowerFlex 755 drive designed to provide application flexibility. Additional features and benefits available include the following floor-mount drives and dual-port EtherNet/IP option module.
PowerFlex 755落地式驱动器IP54 / UL Type 12级 - 用于需要额外保护的应用程序，PowerFlex 755落地式驱动器可提供IP54 / UL Type 12机箱。这些外壳有助于保护驱动器免受灰尘和飞溅水，适用于适度的苛刻室内环境。
PowerFlex 755 Floor-Mount Drives with IP00, NEMA/UL Open-Type Ratings – The open-type drives are designed to provide packaging flexibility, including the option for either vertical or horizontal mounting orientations. This option provides machine builders, system integrators and packagers with the ability to customize the drives by adding specialized content and using the drive packaging of their choice. The drive is available as a series of modules along with user-selected kits.
PowerFlex 750-Series Dual-Port EtherNet/IP Option Module – This new option module for the PowerFlex 753 and PowerFlex 755 drives provides flexible, cost-effective ways to apply EtherNet/IP and supports all three industry-standard Ethernet topologies: star, linear and ring, as well as device-level ring (DLR) functionality.
