Allen-Bradley 20BD248A0ANNANC0 is an adjustable frequency three-phase PowerFlex 700 AC inverter with A 480V AC rating and normal load ratings of 248A and 200 HP at 480V/60 Hz inputs. It uses frame size 6 and has a NEMA Type 1 IP20 housing. The Man Machine interface module (HIM) for this drive is empty and comes with manual documentation. Although the 20BD248A0ANNANC0 driver has an EMC filter and CM choke, it is not equipped with an internal brake resistor, only standard controls. The drive can be installed inside or outside the cabinet, but it is important that its location is free of corrosive particles or volatile vapors, gases, or dust. It should also have an ambient temperature of 0 to 50 °C when running and -40 to 70 °C when the drive is stored. Its relative humidity should also be between 5% and 95%, and have a level 1 or 2 ambient pollution degree. In operation, the 20BD248A0ANNANC0 driver has 1 g peak operating vibration and 15 g peak operating shock in 11 ms (+/ -1 ms). The 20BD248A0ANNANC0 driver has three available motor controls, namely per-hertz volt control, vector control using patented Allen-Bradley Force technology, and sensorless vector control. It also has additional features such as inertial crossing, fly start, overall process PI control, speed and torque specification, high-speed analog input, position indexer/speed curve, current limiting and bus voltage regulation, TorqProve, and programming flexibility.

The Allen-Bradley 20BD248A0ANNANC0 is a PowerFlex 700 adjustable frequency AC inverter. The driver mainly has an input power supply voltage range of 380-480 volts AC 3 phase and provides an output voltage of 0-460 volts AC 3 phase. It has a continuous output current of 248 amps through its applicable output power (200 HP at normal load) and 150 HP at heavy load operation.

As part of the PowerFlex 700 inverter product family, rated at 200 HP, it has inherent features such as integrated EMC filtering; Internal communication; Integrated dynamic brake transistor. It also enables a variety of motor control methods, including volts/Hertz (V/Hz) for fan and pump applications; Sensorless vector control (SVC) for torque regulation. The 20BD248A0ANNANC0 is specially equipped with vector control to provide excellent torque regulation compared to the SVC, including excellent low/zero speed performance. The vector control method utilizes Allen-Bradley's patented technology, FORCE technology.

In addition, the 20BD248A0ANNANC0 features fast current limiting and bus voltage regulation for maximum acceleration and deceleration times without causing the driver to trip. It supports fast start for a smooth and instantaneous connection to a rotating load without speed feedback and is not affected by the direction of rotation of the command motor. It also has an inertial traverse function, which can use stored inertia to prevent the drive from tripping. This feature is useful during power outages.

The 20BD248A0ANNANC0 is also equipped with an integrated proportional + integral (P+I) controller algorithm that makes the drive a standalone controller. This eliminates the need for an external PID controller to operate the drive. It also has a TorqProve function, which ensures that the load is controlled during the transfer of control between the drive and the mechanical brake.
