The 150-A54FCD from Allen-Bradleys SMC-PLUS series is a versatile solid-state motor controller housed in a robust NEMA Type 4 enclosure, ideal for controlling motors and resistive loads. It accommodates 200-600V AC (3-phase) input at 50-60 Hz and generates 54 A output, compatible with motors rated from 1-40 HP at 480V AC. Key features include three operational modes: soft start with a selectable kickstart, current limit start, and full voltage start, along with energy-saving capabilities for lightly loaded or idle motors. Designed with input flexibility, it requires 30 VA of power at 100-240V AC (single phase) and supports easy adjustments via DIP and rotary digital switches. Optional functionalities enhance performance with smart motor braking, slow speed control, and soft stop features. The controller efficiently manages power while maintaining optimal temperatures between 0-50°C, with maximum heat dissipation of 200W. Measuring 245 x 290 x 200 mm and weighing 11.3 kg, it supports cable sizes from 16-120 mm² (#6 to #4/0 AWG) for power terminals and 1.5-4 mm² (#18 to #12 AWG) for control terminals, making it a comprehensive solution for various industrial applications.
