Allen-Bradley 25B-D2P3N114 Variable Frequency Drive

The Allen-Bradley PowerFlex 525 0.75 kW (1 HP) AC drive, model 25B-D2P3N114, provides compact, panel-mount speed and torque control for three-phase motors in automation systems. It accepts 240 V AC input and delivers up to 2.3 A on a three-phase output, with IP20 / NEMA Type Open enclosure and a panel-mount form factor suitable for tight installations. It features V/Hz control and sensorless vector control across a 0–400 Hz range to optimize motor performance and energy use. Commonly installed in small conveyor systems, pumps, fans, mixers, and packaging machinery where precise speed regulation and a compact footprint are required, it is used by maintenance teams, OEMs, and system integrators for equipment replacement, panel integration, and system upgrades that improve overall efficiency. Common replacements include Allen-Bradley 25A-D2P3N104, ABB ACS355-03E-02A4-2, and Siemens 6SL3210-1KE11-8UF1.
