Allen-Bradley 25B-D030N104 AC Variable Frequency Drive

The Allen-Bradley 25B-D030N104 PowerFlex 525 AC Drive is a variable-frequency drive designed to control three-phase motors with up to approximately 20 HP. It accepts 480 V AC, 3-phase input and provides programmable speed control from 0 to 60 Hz, with V/Hz and sensorless vector control for precise torque when needed. The unit comes in an industrial drive housing suitable for panel or enclosure mounting and includes built-in diagnostics and motor protection to help monitor motor health and fault conditions. Optional network modules enable communication over EtherNet/IP, DeviceNet, and other protocols for integration with broader control systems. This PowerFlex 525 family drive is commonly used in conveyor systems, pumps, HVAC equipment, compressors, and general automation machinery where adjustable motor speed improves process control and energy efficiency. Typical operating environments align with industrial-rated conditions, making it a common replacement or retrofit for similar 480 V three-phase drives. The model designation 25B-D030N104 identifies the specific configuration within the PowerFlex 525 series, ensuring compatibility with industrial automation projects requiring robust control and diagnostics.
