Allen-Bradley 20G11ND077AA0NNNNN PowerFlex 755 AC Drive 60HP 77A VFD

Product Description

The 20G11ND077AA0NNNNN (20G11ND077AA0NNNNN) is a high-performance Variable Frequency Drive (VFD) from the Allen-Bradley PowerFlex 755 series. Engineered for sophisticated motor control, this Frame 4 drive provides exceptional integration into EtherNet/IP networks and is designed to handle demanding industrial loads. It features a 77 Amp output rating, capable of supporting up to 60 HP (45 kW) in Normal Duty applications.

This specific configuration, 20G11ND077AA0NNNNN (20G11ND077AA0NNNNN), is an air-cooled, open-type unit (IP20/IP00) optimized for installation within control cabinets or Motor Control Centers (MCC). It incorporates an AC input with a precharge circuit to protect the DC bus components during power-up. Notably, this model includes an internal dynamic braking transistor, allowing for simplified braking resistor connection for high-inertia loads. The unit is supplied with the filtering jumper removed (Type AA) to accommodate specific grounding configurations, and it comes without a pre-installed Human Interface Module (HIM) to allow for modular customization.
