150-F135NCD SMC-Flex Smart Motor Controller

The 150-F135NCD SMC-Flex Smart Motor Controller is a soft starter controller with an integrated by-pass and a modular design that is used for the microprocessor-controlled starting of 3-phase induction motors. The drive is modularly designed to save space and installation time, and its integrated by-pass minimizes heat loss, enclosure size, and operation cost. The drive is in a series of drives which features multiple protection features with flexible communication options and which is designed with LED indicators which display any fault before real damage happens. The 150-F135NCD has 135A, and 60 to 100HP controller ratings at 480V AC and it has an input line voltage range of 200 to 600V AC (3-phase) at 50/60Hz, with an input tolerance of -15% and +10%. It has a power circuit with a 2,200V AC dielectric withstand, and with a peak inverse current of 1600V, and it provides DV/DT protection using an RC Snubber Network.

Product Applications
Conveyors: Ideal for material handling where smooth starts prevent product damage and reduce wear on belts and gears.
Centrifugal Pumps: Includes specific Pump Control modes to reduce fluid surges (water hammer) during starting and stopping.
Fans and Blowers: Provides controlled acceleration for high-inertia loads, preventing belt slippage and mechanical fatigue.
Compressors: Efficiently manages the high torque required during startup while minimizing the impact on the electrical grid.
Crushers and Chippers: Suited for heavy-duty industrial machinery that requires robust protection against stalls and jams.
Positioning Equipment: Utilizing the Accu-Stop and Slow Speed with Braking features, it is used for precise alignment and positioning tasks.

Specialized Operational Modes
Soft Start & Soft Stop: Reduces torque and current spikes during every cycle.
Smart Motor Braking (SMB): Stops motors faster than a coast-to-rest without requiring external resistors or hardware.
Current Limit Start: Limits the maximum starting current to a specific level, which is critical for facilities with power capacity constraints.
Dual Ramp Start: Useful for applications with varying load characteristics, allowing two different start profiles.
