20BD481N3ANNNCD1

The Allen Bradley 20BD481N3ANNNCD1 model is intended for demanding applications requiring robust motor control. This adjustable frequency AC drive operates at a nominal voltage of 480 volts AC and is designed for 3-phase systems. It can handle a significant current capacity of 481 Amperes, catering to high-load scenarios.

This drive does not utilize an Insulated Gate Bipolar Transistor (IGBT) for braking, which streamlines its operation. Instead, it employs a standard encoder (operating at 12 or 5 Volts) for feedback, ensuring precision in motor performance. The bus voltage rating is measured at 648 Volts DC, supporting efficient operation of connected devices.

User interaction with this unit is facilitated through a liquid crystal display (LCD) that includes a full numeric keypad, allowing for straightforward programming and monitoring. The internal communication is managed via a ControlNet coaxial communication adapter, further enhancing the drive's integration capabilities within control systems.

The 20BD481N3ANNNCD1 features fan cooling for temperature management. It has a protection class rating of IP00 and comes in an open enclosure, which is treated with a conformal coating to provide some degree of protection against environmental conditions. It is classified within frame size 8, which defines its physical dimensions for mounting. The sensorless vector control capability is supported with an input and output specification of 115 Volts AC. Overall, this drive offers necessary functionalities for a variety of industrial applications.
