The Allen-Bradley 150-C43NBR SMC-3 Smart Motor Controller, part of the 150 SMC-3 series, is engineered for efficient motor control with its simple solid-state design. With inline input voltages ranging from 200 to 480V AC at 50-60Hz and handling a current of 43A, it ensures robust motor operation while offering 1000V/ µs DV/DT protection. This controller provides advanced protection features, including a 150A non-time-delay K5 fuse and a thermal magnetic circuit breaker, along with a control circuit operational voltage of 24V AC/DC and 2500V impulse capability. Its smart functionalities include a soft start for torque management with an adjustable start time, alongside current limit and soft stop modes. Designed for thermal efficiency, it operates with 34W heat dissipation and maintains performance up to 2000m altitude with environmental tolerance of 0-55 °C and 5-95% non-condensing humidity. Suitable for open environments with an IP2X rating, this unit is compact at 72mm x 206mm x 130mm and is CCC, c-UL-us, CSA, CE certified, also offering Delta Compatibility for diverse motor applications.
