Rockwell Automation PowerFlex 7000 AC Drives

Series AC converters PowerFlex 7000 designed to control asynchronous and synchronous electric motors for high voltage applications from 2300 to 6600 V It is a highly efficient solution for conducting heavy-duty production processes, the range of capacities used reaches the limit in 24,500 kW. Advanced functionality for precise control of speed, torque and direction of rotation. Due to the peculiarities of the technology used, these electric drives can simultaneously boast of simplicity of architecture and versatility of application in a wide range of industrial sectors. A high degree of adaptability and a wide range of offers provide an exhaustive choice for solving a wide variety of project tasks.

For the comfort of interaction and visualization of the functionality of the intelligent control system, an intuitive interface of the operator panel with a color touch screen is used, as well as configuration using modern configuration software, remote control. There are three types of rectifiers: Direct-to-Drive technology (no transformer is required for connection), active (AFE) and 18-pulse. High level of safety for personnel and equipment, built-in algorithm for safe torque shutdown, mechanical locking methods. The monitoring and diagnostic tools used in the work make it easy to find faults and avoid long downtime.

The product range includes versions with air (size A and B) and liquid (size C) cooling systems, as well as a range of high-power converters, special modifications for marine applications. In addition to the standard design, reinforced ArcShield arc-resistant enclosures are available, earthquake-resistant, with increased IP42 penetration protection. Custom settings for specific operating conditions are also available to order.
