The Allen Bradley 20AD3P4A3NYYNCNN is a versatile component within the PowerFlex 70 series, serving as a variable speed drive (VSD). This unit operates effectively at an input voltage of 480 VAC, utilizing a three-phase setup. Capable of handling a power rating of 1.5 kW, or 2 horsepower, the drive supports an output current of up to 3.4 A, allowing for precise motor control.
The 20AD3P4A3NYYNCNN drive features a panel-mounted installation style, designed for simple integration. Users benefit from a fully numeric LCD interface, which facilitates straightforward monitoring and adjustments. The 20AD3P4A3NYYNCNN drive incorporates a built-in dynamic braking resistor, complemented by an electromechanical brake assembly, for enhanced performance during rapid deceleration.
However, this variable speed drive does not offer internal EMC filtering. Connectivity is achieved via a ControlNet communication port, which supports integration into larger control networks. The drive operates in a standard open-loop control mode, and it does not include an encoder interface for feedback, simplifying its design.
