Product Overview
The Allen Bradley 20BD077A0ANNANA0 PowerFlex 700 AC Drive is a high-performance Variable Frequency Drive (VFD) designed to provide precise speed control, outstanding torque performance, and reliable motor protection for demanding industrial automation applications. As a member of the renowned PowerFlex 700 series from Rockwell Automation, this drive combines advanced vector control technology, flexible configuration options, and intelligent diagnostics to improve machine productivity while reducing energy consumption and maintenance costs.
Designed for 480 VAC three-phase power systems, the 20BD077A0ANNANA0 provides a rated continuous output current of 77 A and supports 60 HP (45 kW) Normal Duty motor applications. By converting fixed-frequency AC input into adjustable voltage and frequency output, the drive delivers smooth acceleration, accurate speed regulation, and stable torque across a wide operating range.
This configuration features 24 VDC control I/O, sensorless vector control, a blank cover without a Human Interface Module (HIM), standard RS-485 (DPI) communication, no factory-installed industrial network communication module, no brake IGBT, no internal braking resistor, and an integrated EMC filter with common-mode choke for improved electromagnetic compatibility. Its modular design also allows optional communication adapters such as EtherNet/IP, DeviceNet, ControlNet, and PROFIBUS to be added according to system requirements.
With dimensions of 758.8 × 201.7 × 220 mm and an approximate weight of 24.49 kg, the drive is suitable for cabinet-mounted industrial control systems where high reliability, efficient cooling, and simplified maintenance are essential.
Typical applications include conveyor systems, compressors, pumps, fans, mixers, packaging machinery, material handling systems, process equipment, HVAC installations, mining machinery, water treatment plants, and OEM industrial automation equipment.
