The part number 20BD248A3NNNANC1 is an adjustable frequency AC drive designed by Allen Bradley within the PowerFlex 700 series. It is engineered for three-phase input systems, operating at a standard voltage of 480V AC and a frequency of 60Hz, making it suitable for demanding electric motor control applications.
This AC drive can handle a substantial current of 248 Amps while delivering a power output of 200HP. Its robust design is complemented by a conformal coating, providing additional protection against environmental factors. The enclosure is rated IP20, adhering to NEMA/UL Type 1 safety specifications, suitable for indoor environments.
User interactions are facilitated through an LCD display, accompanied by a full numeric keypad. However, the design lacks an internal brake resistor and does not have a brake IGBT. The drive integrates CE filtering and a common mode choke, which mitigate electrical noise and promote reliable operation.
The drive supports extensive I/O options, providing six digital inputs, three digital outputs, two analog inputs, and two analog outputs, enhancing versatility in various control systems. The encoder input is dual-channel, supporting 12 V DC and a maximum current of 250 mA, allowing precise feedback for applications requiring accuracy. Finally, the maximum output frequency is configured at 400 Hz, with an optional extension to 420 Hz, increasing its flexibility to meet specific operational demands.
