The Allen-Bradley 150-A97NC is a three-phase soft-starter smart motor controller from the SMC-2 series, designed for solid-state control with a power range of 500 to 575V AC at both 50 and 60 Hz. This advanced controller supports motor applications up to 97A and offers a maximum horsepower rating of 30 HP at 200 and 230V AC, scaling up to 75 HP at 460 and 575V AC, alongside a robust kW capacity of up to 63 kW at 500V AC. Key features include energy-saving functionality for light or idle loads, three operational modes—current limit start, full voltage start, and soft start—and user-friendly configuration through a rotary digital switch, DIP switches, and an LED status indicator monitoring critical parameters. Engineered for environments within 0 to 50 °C and altitudes up to 2000 meters, this controller is housed in an open NEMA type enclosure, dissipates up to 285W of heat, and weighs approximately 10.5 kg.
