Allen-Bradley 25B-D1P4N104 PowerFlex 525 AC Drive

The Allen-Bradley PowerFlex 525 25B-D1P4N104 is a compact 0.4 kW (0.5 HP) AC drive designed to deliver precise speed control for 380–480V three-phase motors. The drive provides 1.4 A rated output current and 0–460 V output with a 0–500 Hz range, using V/Hz control and Sensorless Vector control for stable performance across light industrial loads. With integrated EtherNet/IP, it can be readily networked into PLC-based control systems for coordinated automation. It comes in an IP20 open enclosure for panel-mount installations and operates from 0°C to 50°C without derating in typical environments. Common applications include small conveyors, dosing and packaging equipment, HVAC components, and other compact machines that require accurate speed control. Maintenance teams, OEMs, and system integrators use this PowerFlex 525 for panel retrofits, equipment repairs, system upgrades, and replacement of existing VFD units in PLC-based control environments. Related part numbers such as 25B-D2P3N104 and 22B-D1P4N104 are common replacements.
