150-B54NBRA

The 150-B54NBRA smart motor controller by Allen-Bradley is an intelligent smart motor controller form the SMP Dialog plus family of controllers that are designed to provide microprocessor starting for 3-phase squirrel-cage induction motors. The SMC Dialog plus controller family are designed to provide smooth acceleration without arcing, chattering, or vibration to significantly reduce maintenance and production costs. The 150-B54NBRA smart motor controller has a current rating of 54 Amps at 480 Volts AC and it is suitable for controlling motors with 5 to 100 Horsepower ratings. It has an integral control module with 24 Volts AC/DC control voltage and it has an RC snubber network which provides DV/DT protection. The 150-B54NBRA smart motor controller incorporates electronic motor overload protection as one of its standard protective features, and it features stall protection and detection capabilities for preventing mechanical damages and winding insulation break down. The 150-B54NBRA smart motor controller also features the highly dynamic phase rebalance feature, which helps to compensate for any voltage unbalance.

The 150-B54NBRA smart motor controller offers the full voltage start, dual ramp start, current limit start, and the soft-start (with a selectable kick start) as standard starting modes, and the optional soft stop modes, which is suitable for applications requiring extended stop (e.g. high friction load application). The 150-B54NBRA smart motor controller features seamless programming and control via its integral LCD and keypad, and it has built-in SCANport Communication port that allows for interfacing with a compatible HMI and communication modules for more sophisticated programming, control, monitoring, and troubleshooting processes. The 150-B54NBRA smart motor controller has 3 auxiliary hard contacts that can be programmed for Normal/Fault or Normal/Up to speed control. It has an open-type of design and it is designed for use at an ambient temperature range of 0 to 50 degrees Celsius. The 150-B54NBRA smart motor controller has an average shipping weight of 25 pounds, and total mounting dimensions of 11.42 x 9.61 x 8.86 inches.
