20BD077A3ANNAND1

In the PowerFlex 700 series, the Allen Bradley model 20BD077A3ANNAND1 stands as a robust adjustable frequency AC drive. Designed to handle an input voltage of 480 Volts AC, it effectively manages a power rating of 45 kilowatts, achieving a rated horsepower of 60. The drive's design allows it to operate within three-phase systems, providing a rated current of 77 Amperes.

This unit does not feature an internal dynamic brake transistor for braking applications. Filtering is implemented through the inclusion of a CE filter along with a Common Mode (CM) choke, which improves the overall electrical performance and reduces harmonic distortion. Control is achieved via vector control methods, ensuring precision in motor management with input and output functioning at 115 Volts AC.

For feedback accuracy, the drive is compatible with a dual-channel incremental encoder, supporting either 12 Volts or 5 Volts configurations. The encoder duty cycle is estimated at approximately 50%, enhancing responsiveness in control applications. Moreover, the drive includes safety measures such as overvoltage and undervoltage trips at 570 Volts AC and 280 Volts AC, respectively.

The 20BD077A3ANNAND1 is designed to operate efficiently in a protected environment, with an allowable temperature range spanning from 0°C to 50°C, as long as conditions remain non-condensing. Additionally, its IP20-rated enclosure equipped with a conformal coating reinforces its durability and operational reliability in various industrial settings.
