A-B 150-C85NBD
The Allen-Bradley 150-C85NBD is an intelligent motor controller from Rockwell Automation’s SMC-3 family. It is mainly used to control the three-phase induction motor to achieve soft start, soft stop and other functions to protect the motor and extend its service life. By controlling the start and stop process of the motor, the impact on the power grid is reduced and the working performance of the motor is improved.
Product parameters and specifications (specific parameters may vary depending on the model and configuration, please refer to the official data)
Type: Intelligent motor controller
Voltage: 480V 60Hz (line voltage)
Control voltage: 100-240V AC
Control mode: microprocessor control, silicon controlled rectifier (SCR)
Functions: soft start, soft stop, overload protection, undervoltage protection
Cooling method: self-cooling
Mounting method: DIN rail mounting
Main function
Soft start: Start the motor by gradually increasing the voltage to reduce the starting current and reduce the impact on the power grid and mechanical system.
Soft stop: Stop the motor by gradually reducing the voltage to reduce the braking impact and extend the mechanical life.
Overload protection: When the motor is overloaded, the controller will automatically cut off the power to protect the motor.
Undervoltage protection: When the power supply voltage is too low, the controller will automatically stop the motor to prevent motor damage.
Application field
Pump: Control the start and stop of the pump to reduce water hammer phenomenon.
Fan: Control the start and stop of the fan to reduce the impact on the power grid.
Compressor: Control compressor start and stop, protect the motor.
