Allen-Bradley 25B-D1P4N114 Variable Frequency Drive

The Allen-Bradley PowerFlex 525 25B‑D1P4N114 is a 0.4 kW (0.5 HP) three‑phase variable frequency drive that precisely regulates speed and torque for small industrial motors in automated systems. Installed in motor control panels and machine cabinets, it provides smooth start/stop and built‑in motor protection to optimize performance and energy use. Key specs include an input voltage range of 323–528 V AC three‑phase, an output frequency range of 0–60 Hz, and a rated output current of approximately 1.4 A, with V/f control and adaptive motor control features; a built‑in LCD/keypad interface for setup and monitoring; and optional EtherNet/IP or DeviceNet communications modules for integration. Mounting is suitable for panel or enclosure installation, and it carries UL/cUL and CE certifications for industrial environments. Typical applications encompass fans, pumps, conveyors, mixers, compressors, and material handling equipment in manufacturing, HVAC, water/wastewater, and packaging facilities.
