150-SC1FBD

The Allen Bradley 150-SC1FBD serves as a highly efficient solid-state smart motor controller within the SMC-50 series. Engineered with a controller rating of 140 A, it ensures reliable performance across a range of demanding applications. Designed for environments requiring resilience, its NEMA Type 4/12 enclosure provides an IP65 rating, allowing it to withstand various conditions.

This unit accommodates line voltages from 400 to 460 volts AC, making it suitable for diverse industrial motor systems. It manages motor sizes from 60 to 150 horsepower while supporting motor currents between 70 and 210 A. The controller features a linear start function, which facilitates smooth motor acceleration, thus enhancing system stability during startup.

The trip current is carefully set to 118% of the full load current (FLC), providing essential protection against overload conditions. Furthermore, in case of temporary disturbances, the control power ride-through duration is specified as 22 ms, ensuring ongoing operation during brief outages.

Its operating frequency covers a range of 47 to 63 Hz, or it can accept DC control supply input, granting flexibility for various applications. For added reliability, it includes transient protection via MOV suppression rated at 220 joules and can withstand surges with a peak inverse rating of 1400 volts. The unit also meets dielectric withstand standards with a rating of 2500 volts per IEC, reinforcing its capability to perform effectively in challenging conditions.
