Allen-Bradley 160-BA04NPSI Variable Speed Drive

Allen-Bradley 160-BA04NPSI is a 2 HP AC Smart Speed Controller from the Bulletin 160 family designed to deliver open-loop speed control for three-phase motors on 380–460 V systems. Implemented in an IP20, open-style enclosure, the unit is compact for panel- or machine-mount installations and includes a Ready/Fault indication panel for quick status checks. This BA04 variant provides preset-speed operation via the NPS interface, aligning with other BA04NPS configurations while maintaining a 380–460 VAC, 3-phase input and a 4 A continuous current rating. With a 2 HP output rating, it is intended for small to mid-size industrial motors, enabling smooth acceleration, controlled deceleration, and stable speed during operation. It is commonly used to drive three-phase motors in standard automation tasks where precise speed control is required, such as handling conveyors, pumps, or fans in suitable duty cycles.
