The 20BD248A5ANNANC1 adjustable frequency AC drive produced by Allen Bradley falls within the PowerFlex 700 series, making it suitable for sophisticated motor control in industrial settings. This unit is specifically designed for three-phase systems and is rated for an input voltage of 480V AC. It boasts a substantial maximum current capacity of 248 Amps, providing a robust 200 horsepower output for demanding applications.
Engineered to operate at a frequency of 60 Hz, the drive has a maximum output frequency capability of 400 Hz, with an optional increase to 420 Hz for specialized requirements. In terms of housing, it features an enclosure with an IP20 rating and meets NEMA/UL Type 1 standards, indicating a reliable level of protection for indoor use.
For I/O capabilities, the drive accommodates 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs, supporting complex control schemes and additional integrations. An encoder input is provided, capable of 12 V DC and dual-channel operation at 250 mA, which is essential for accurate feedback in motor control applications. There is no brake IGBT or internal brake resistor included, simplifying the design while ensuring efficient performance.
Lastly, a conformal coating adds a protective layer to the drive, safeguarding its components from potential environmental factors. The inclusion of CE filtering and common mode choking helps to mitigate electrical noise and ensures compatibility within various industrial systems.
