150-F201NBRB Description

The 150-F201NBRB Smart Motor Controller is a high-capacity solid-state soft starter from the SMC™ Flex series, 

designed to provide smooth motor starting, stopping, and protection in industrial applications.
This 150-F201NBRB controller uses thyristor-based control technology to gradually ramp motor voltage during 

startup, reducing mechanical stress, electrical inrush current, and wear on equipment. It is ideal for medium-to-large 

motors used in demanding processes such as pumps, compressors, and conveyors.

Product Applications

Water treatment and pumping stations: The model suffix "RB" usually includes a pump control (Pump Control) option. 

It can effectively eliminate the "water hammer" phenomenon in the pipeline system and is suitable for municipal water 

supply and drainage, as well as industrial circulating water systems.
Manufacturing and processing plants: Used for controlling conveyor belts, mixers, crushers, and large fans. Its soft 

start function can reduce mechanical shock during startup and extend the service life of belts and gears.
Mining and quarries: Widely used in rock crushers, heavy conveyors, and other high-load equipment, helping the 

equipment start smoothly under limited power grid capacity.
Food and beverages: Used in filling lines, centrifuges, and freezer pump groups to ensure smooth production and 

comply with hygiene and safety standards.
HVAC (Heating, Ventilation, and Air Conditioning): Motor control for water chillers in large factories and industrial 

cooling tower fans.

Typical application scenarios
Air compressor: Provides controlled acceleration to prevent excessive current peaks during startup, which could 

cause fluctuations in the power grid.
Forging cleaning drum / centrifuge: Utilizes its optional braking function (Smart Motor Braking) to achieve rapid 

shutdown, enhancing production efficiency.
Long-distance belt conveyor: Supports dual ramp start-up (Dual Ramp), allowing the adjustment of starting torque 

based on load changes to reduce belt wear.
Constant speed positioning equipment: Through the low-speed (Slow Speed) operation mode, assists the equipment 

in achieving precise positioning or alignment operations.
