The Allen-Bradley 150-A97NBDA is a smart-motor controller with a compact design. It is ideal for use with a microcomputer starting for three-phase squirrel cage induction motors. To operate smoothly, this controller device requires an alternate current voltage of 200 volts alternate to 480 volts. This advanced motor controller features -15% to +10% voltage tolerance levels at 50/60 Hz. As far as rating is concerned, the Allen-Bradley 150-A97NBDA comes with a 97-ampere rating. It supports an output power of 5.5 kilowatts (75 horsepower). To avoid errors and downtime due to overheating, this smart controller unit comes with a heat dissipation rate of 285 watts. When it comes to protection against thermal anomalies, this module comes with an IEC/NEMA MG1 rating capacity. The Allen-Bradley 150-A97NBDA comes with a 45 VA heatsink fan that provides solid cooling and temperature control options. Thanks to the built-in RC Network, this smart controller module can avoid undesired outcomes due to sudden current surges and DV/DT spikes. When it comes to building components, the Allen-Bradley 150-A97NBDA includes high-temperature thermoplastic power poles and thermoplastic controls in its design. When it comes to building material, this smart controller uses anodized aluminum, plated brass, or copper metal parts. Using the single controller unit, users can deploy the controller for three different standard modes of operation: soft start, current limit, and full voltage start. To fend off phase loss and shorted SCRs, this smart controller module includes pre-start protection. Users can assess the state of this controller unit by looking at any of the indicator lights. The LED indicators show the status of the unit and stall protection for starting and running conditions. To ensure low load conditions, the Allen-Bradley 150-A97NBDA comes with an inbuilt energy saver option.
