Allen-Bradley 20BB028A0AYNBNC0 Variable Frequency Drive

The Allen-Bradley PowerFlex 700 20BB028A0AYNBNC0 is a 10 HP variable frequency drive (VFD) that precisely controls three-phase AC motors, delivering adjustable speed and torque for reliable motor performance in automated systems. Installed in motor control centers, panelboards, and machine cabinets, it provides soft-start/stop control and energy-efficient operation to improve process responsiveness and reduce mechanical stress. The PowerFlex 700 offers 0–60 Hz output, with input typically 380–480 V AC three-phase, and supports control methods including V/f, sensorless vector, and advanced torque control (model-specific); optional Ethernet/IP and DeviceNet communications modules extend network integration, while the integrated LCD/keypad enables on-site monitoring and parameter setup. Built-in protection covers overload, overcurrent, overvoltage, and ground-fault protection, and the drive is UL/cUL and CE certified for industrial use; mounting supports panel or enclosure installations. Applications include pumps, fans, conveyors, compressors, mixers, and material-handling machinery where precise speed regulation and smooth performance drive efficiency and control in manufacturing, HVAC, water treatment, and packaging lines.
