Allen-Bradley 161S-AA10NPU Controller

Allen-Bradley 161S-AA10NPU is a compact 3 HP (2.2 kW) AC drive from Rockwell Automation's Bulletin 161S family, designed to deliver variable-frequency control to small three-phase motors. It is rated for 200–230 VAC input and provides a three-phase output at adjustable frequencies from 0.5 Hz up to 360 Hz, enabling precise motor speed and torque management. The drive is housed in an IP20 enclosure and supports 50/60 Hz operation, making it suitable for panel-mounted installations in standard industrial environments. As a Series B member of the 161S family, the AA10NPU variant shares the same compact form factor as the line's other models, while delivering a 3 HP motor rating at 230 VAC. It is designed for straightforward setup and integration into control schemes that require variable-speed drive capability, with official documentation guiding installation, wiring, and parameter configuration for this model.
