Allen-Bradley 160-BA03NPS1 Variable Speed Drive

Allen-Bradley 160-BA03NPS1 is a compact AC Smart Speed Controller (Bulletin 160 SSC) designed to provide straightforward speed control for small three-phase induction motors. It accepts 380–460 V AC, three-phase input at 50/60 Hz and delivers up to 2.3 A to the connected motor, supporting a motor rating of 0.75 kW (1 HP). This preset-speed controller is offered in an open IP20 enclosure and is intended for DIN-rail or panel mounting, with overall dimensions of about 6 in (H) by 3.15 in (W) by 6.51 in (D) and a weight of roughly 2.24 lb. The device uses a voltage/frequency (V/Hz) control method and is part of the 160 SSC family, providing a Ready/Fault indication for quick status checks in process environments. Typical applications include small, non-networked drives where fixed or limited-speed variation is sufficient for a single 3-phase motor. The 160-BA03NPS1 is discontinued/obsolete, so it is primarily encountered in surplus or refurbished inventories. Overall, it offers a compact, easy-to-install solution for reliable basic speed control of moderate-capacity 3-phase motors without advanced tuning or network integration.
