150-A97NBD-8L4

The Allen-Bradley 150-A97NBD-8L4 controller is an SMC-2 series solid-state motor controller that is rated at 97 Amps of current. The enclosure on the 150-A97NBD-8L4 motor controller is open. The input line voltage range is 380 to 460 Volts AC (three-phase, at 50 to 60 Hertz). The 150-A97NBD-8L4 controller comes with a protection module for line side protection that is rated for 460 Volts AC. The protective module is required for applications where the controller can be exposed to abnormal or high line transients. The protective module contains snubber networks to shunt away the noise energy and Metal Oxide Varistors (MOVs) that protect the SCR from line surges. The open-type 150-A97NBD-8L4 controller is a stand-alone SMC-2 controller rated for a maximum of 55 kilowatts and with a 1 to 75 Horsepower range.

SMC-2 controllers like the 150-A97NBD-8L4 controller can be used as standard series controllers or as controllers with an interface option. The standard series controller is designed to operate in series with an electromechanical motor starters. This series mode eliminates the need for additional control wiring and it enables easy setup with easy digital adjustments. The controller with an interface option can be used without an electromechanical motor starter and it provides the following features: direct on/off control through an external pilot device, a selectable auxiliary contact, and a soft stop feature. The SMC-2 series controllers are CSA certified and CE marked. The peak heat dissipation for the 150-A97NBD-8L4 controller is 285 Watts. The 150-A97NBD-8L4 controller weighs approximately 10.5 kilograms and it measures 336 x 248 x 230 millimeters. The cable used for terminations on the power terminals of the controller should be 50 millimeters square, and for the interface terminals, the cable size is #1/0 AWG.
