Allen-Bradley 25B-B2P5N104 Variable Frequency Drive

The Allen‑Bradley PowerFlex 525 drive, model 25B-B2P5N104, is a compact 0.4 kW (0.5 HP) AC variable-frequency drive with a 200–240 V three‑phase input and a rated output of 0.4 kW (0.5 HP) at up to 2.5 A. Housed in Frame A with an IP20/NEMA open-type enclosure and no external filter, it is designed for panel mounting in light‑to‑moderate duty applications. It includes embedded EtherNet/IP connectivity and safety features for networked automation and Safe Torque‑Off capability, making it well suited for integrated control in small machinery. The drive supports 0.5 HP performance in both normal and heavy‑duty configurations and offers motor-control options such as V/Hz with sensorless vector performance to improve speed regulation on smaller motors. Typical use cases include conveyors, pumps, fans, and other equipment requiring reliable, compact speed control with straightforward network integration in 240 V three‑phase systems. This model is specifically designed for 240 V three‑phase operation and targets installations where a space‑saving, easily networked drive with solid motor protection is desirable.
