Rockwell Automation PowerFlex 525 AC Drives

Compact series of AC drives PowerFlex 525 from the company Rockwell Automation (Allen-Bradley) It is designed to control asynchronous and synchronous electric motors with a capacity of up to 22 kW. In comparison with the younger 523 series, they have more extensive process management capabilities. Four types of speed parameter control using feedback sensors and sensorless modes, sequential positioning are implemented, and there is also an energy-saving operation algorithm to save consumed resources.

They are characterized by optimal flexibility and ease of installation and configuration, for ease of interaction, the drives can be equipped with a graphical interface for both integrated and remote mounting. A rich arsenal of software products for configuring and maintaining production processes is provided. Built-in EtherNet/IP port, easy integration into the Logix environment, and modules for industrial protocols are also available.

Practical modular design, the model range has five overall offers, four types of network power characteristics, two types of operation modes with periodic load. A wide range of optional blocks to obtain the optimal variant of the technological equipment of the drive. They are capable of operating at ambient temperatures from -20 to 50 °C (up to 70 °C with additional preparation). Horizontal and vertical mounting, including close to each other.
