Allen-Bradley 20G11ND052AA0NNNNN Variable Frequency Drive

PowerFlex 755 AC drive, Allen-Bradley 20G11ND052AA0NNNNN, is an open-type, air-cooled variable-frequency drive designed for 480V three‑phase motor control. It provides a 52 A continuous input current rating and is configured for 480 VAC input with DC terminals on the input side, and it includes embedded EtherNet/IP for plant‑floor networking and remote configuration. This model is built for general‑purpose motor control in industrial environments, delivering precise speed and torque management for loads such as conveyors, pumps, and fans when integrated with Rockwell Automation hardware and software. The open architecture supports installation in control panels or on machine frames, with standard 3‑phase power and DC‑link connections, while maintaining compatibility with the PowerFlex 755 family’s protection features and straightforward network communication. The device embodies the PowerFlex 755 design philosophy of scalable performance, easy wiring, and reliable integration into Rockwell Automation ecosystems, making it a suitable choice for mid‑range automation projects that require networked drive control.
