Hardware Comparison: PowerFlex Selection Guide: 523 vs. 525 vs. 527
Allen Bradley Powerflex 520 series drives are an innovative take on modular drive configuration. Common power structures and form factors allow for interchangeability between 3 versions of the 520 series drive, the 523, 525, and 527. Each version adds to the performance options available and allows for easy upgrading of drive systems and reduces maintenance and spares requirements. There are some common features among the 520 series drives. Common frame sizes, 0.5-30HP power ratings, 100-600V voltage ratings, local HMI’s for programming, and the ability to zero-stack and mount either vertically or horizontally are just some of the more prominent ones. The 523 series drive is the baseline drive of the 520 series. Available in voltage ranges from 100-600 volts and power ranges from 0.25-30HP, these drives include a local HMI and the ability to add EtherNet/IP capability through a dual-port accessory module, among other things. This is the baseline drive of the family, typically...
