【英文介绍】

Allen-Bradley 20BD248A0ANNANC0 is an adjustable frequency three-phase PowerFlex 700 AC inverter with A rated voltage of 480V AC, rated voltage of 248A, normal duty cycle of 200 HP, input voltage of 480V. The frequency is 60 Hz. It uses a frame size of 6 and has a NEMA Type 1, IP20 housing. The Man Machine interface module (HIM) for this drive is blank and it 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 in storage). 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 a peak operating vibration of 1 g, a peak operating shock of 15 g, and a duration of 11 ms (+/ -1 ms). The 20BD248A0ANNANC0 driver has three available motor controls, voltage per Hertz, vector control using patented Allen-Bradley Force technology, and sensorless vector control. It also has additional features such as inertial crossing, fly start, integrated process PI control, speed and torque regulation, high-speed analog inputs, position divider/speed profiler, current limiting and bus voltage regulation, TorqPrve, and programming flexibility.

The Allen-Bradley 20BD248A0ANNANC0 is a PowerFlex 700 adjustable frequency AC inverter. The driver mainly has an input supply voltage range of 380-480 volts AC (three-phase) and provides an output voltage of 0-460 volts AC (three-phase). It drives the connected motor through its applicable output power (200 HP under normal conditions) and an output power of 150 HP during heavy duty operation, as well as a continuous output current of 248 amps.

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 supports 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 and offers 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 flying start and is used to establish a smooth and instantaneous connection to the 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 prevents the drive from tripping by utilizing the inertia of the storage. This feature is useful during power outages.

The 20BD248A0ANNANC0 also features an Integral proportional + integral (P+I) controller algorithm that makes the drive an independent controller. This eliminates the need for an external PID controller to operate the inverter. 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.
