The 25B-D2P3N114 is a model number for a Rockwell frequency converter. Rockwell Automation is a leading manufacturer of industrial automation equipment, including variable frequency drives (VFDs) or inverters, commonly referred to as frequency converters.

The 25B-D2P3N114 is a specific model of the PowerFlex 525 series frequency converter manufactured by Rockwell Automation. It is designed to provide variable speed control to three-phase induction motors, allowing for precise control of motor speed and improved energy efficiency.

Here's a breakdown of the model number:

- "25" indicates the series or family of the frequency converter (PowerFlex 520).

- "B" represents the frame size of the converter. Different frame sizes correspond to different power ratings and physical dimensions of the unit.

- "D2" indicates the input voltage rating. In this case, it likely represents a 200-240V AC three-phase input.

- "P3" refers to the capacity or power rating of the converter. It denotes the maximum continuous output current or horsepower rating.

- "N114" is a variation code that may specify certain options or features specific to that model.
