Allen-Bradley 160S-AA03NSF1 Safety Relay Module

Allen-Bradley 160S-AA03NSF1 Smart Speed Controller is a compact AC drive that converts a 200-240 V single-phase supply into a 200-230 V three-phase output to power small motors. It handles a motor rating of 0.55 kW (0.75 HP) and delivers up to 3.0 A on the three-phase side, while drawing about 6.2 A from the 200-240 V input at 50/60 Hz. The drive offers variable speed control from 0 to 240 Hz, enabling precise adjustments for light-duty applications. The AA03NSF1 designation identifies the 0.55 kW, 1-ph input configuration in the 160S family, which is designed for general-purpose speed control in compact control panels. Typical use cases include small three-phase motors in general-purpose equipment where a single-phase supply must be converted to three-phase, such as fans, pumps, or light conveyors, all within a compact form factor suitable for panel mounting in standard enclosures. This model provides the essential features of the 160S line for straightforward speed regulation, smooth acceleration, and reliable, energy-efficient motor control in compact automation setups.
