20BD248A3AYNARA0

The PowerFlex 700 series features the 20BD248A3AYNARA0, which is a highly efficient adjustable frequency AC drive designed for high-demand environments. This particular drive operates at a line voltage of 480 VAC, ideal for heavy-duty applications requiring reliable performance. It supports a maximum current rating of 248 Amps and provides an impressive 200 horsepower output.

The enclosure is rated at IP20, adhering to NEMA/UL Type 1 standards, making it appropriate for use in cleaner indoor settings where dust and moisture exposure is minimal. The internal features include a conformal coating that protects the electronics from environmental factors. An integrated Human-Machine Interface (HMI) with an LCD display and full numeric keypad facilitates easy monitoring and adjustment of operation settings.

Control is achieved through a sine-coded pulse-width modulation (PWM) method, which provides efficient motor control. The carrier frequency can be adjusted to meet specific application needs, with selectable rates of 2, 4, 8, or 10 kHz. Output voltage can vary from 0 to the rated voltage, ensuring flexibility in operation.

Safety features are significant in this drive, with an AC overvoltage trip set at 570 VAC, and an undervoltage trip at 280 VAC. The drive includes a brake IGBT for effective braking capabilities. However, note that it does not come with an internal braking resistor, which may need to be accounted for depending on the specific requirements of the application.
