Allen-Bradley 25B-D030N114 Variable Frequency Drive

Allen-Bradley 25B-D030N114 PowerFlex 525 is a 15 kW (20 HP) three-phase variable-frequency drive designed to regulate speed and torque of AC motors in industrial control systems. It accepts 240 V AC input and delivers up to 30 A of output current, with V/Hz and sensorless vector control to handle a range of load profiles and provide smooth acceleration. The drive supports a 0–400 Hz output frequency range and comes in an IP20 enclosure with Open NEMA configuration for panel mounting. Typical applications include conveyors, pumps, compressors, fans, and other heavy-duty equipment where precise speed control improves process stability and energy efficiency. It is commonly used by maintenance teams, OEMs, and system integrators for equipment replacement, control panel upgrades, retrofits, and energy optimization in manufacturing plants, water and wastewater facilities, oil and gas operations, and material handling systems.
