20BD077A3ANNARD1

The Allen Bradley 20BD077A3ANNARD1 is an adjustable frequency AC drive specifically designed to offer robust motor control capabilities. Operating at an input voltage of 480V AC, this drive supports high-performance applications with a nominal current rating of 77 Amperes and a rated output of 45 kilowatts. This translates to a corresponding horsepower rating of 60.

This drive operates on a 3-phase input and features a control input/output of 24 volts AC/DC vector control, enabling precise motor regulation. It is also equipped with a ControlNet communication adapter, allowing for effective network integration.

For enhanced performance, the drive utilizes a brake IGBT (Insulated-gate Bipolar Transistor), which provides reliable braking capabilities. The cooling of the unit is managed by a fan, ensuring optimal thermal conditions during operation.

With regard to design, the unit features a human interface module that includes a liquid crystal display along with a full numeric keypad, allowing for user-friendly control and monitoring. It is important to note that this module functions without encoder feedback.

The 20BD077A3ANNARD1 also includes a CE filter and a common mode choke for effective signal filtering, thus minimizing electrical interference in the system. Its NEMA Type 1 enclosure offers appropriate protection against environmental risks, ensuring reliable operation in typical industrial settings, where relative humidity can range from 5% to 95%. Overall, this adjustable frequency AC drive is ideal for applications demanding both control precision and robust performance.
