Allen-Bradley 25A-D1P4N104/B Variable Frequency Drive

The Allen-Bradley 25A-D1P4N104/B Variable Frequency Drive from the PowerFlex 25A family is a compact panel-mount VFD designed for 380–480V three-phase service and delivers 0.4 kW (0.5 HP) to small, three-phase motors. It provides 0–460V AC output up to 500 Hz with a rated output current of 1.4 A and uses V/Hz control to maintain torque across speed ranges in light-duty conveyors, pumps, fans, and automated machinery. This open-type IP20 enclosure is suitable for standalone machines or control panel retrofits in industrial environments, with an ambient operating range of 0°C to 50°C without derating, making it a common choice for packaging lines, material handling conveyors, HVAC components, dosing systems, and compact machine builds. Common replacements for this drive include Allen-Bradley 25B-D1P4N104 and 22B-D1P4N104.
