Allen-Bradley 25A-D024N114 PowerFlex 523 VFD 15kW 20HP

Product Overview

The Allen-Bradley 25A-D024N114 is a high-performance Variable Frequency Drive (VFD) from the PowerFlex 523 family, specifically engineered for standalone machine-level control. This Frame D drive features an IP20 NEMA / Open Type enclosure, offering a compact footprint for cabinet mounting. Developed by Rockwell Automation, it provides an economical and reliable solution for applications requiring 15 kW (20 HP) of power, combining ease of use with flexible motor control options for three-phase 480V systems.

Power and Efficiency Performance

Designed for maximum energy savings, the 25A-D024N114 boasts a typical efficiency rating of 97.5%. It accepts a 480 VAC Three-phase input and provides a 24 Amp continuous output current. The drive's output frequency is fully programmable from 0 to 500 Hz, allowing for high-speed motor operation. Its ability to maintain a consistent output voltage range from 0V up to the rated motor voltage ensures smooth torque delivery across the entire speed spectrum, reducing mechanical wear on connected equipment.

Physical Characteristics & Weight

The 25A-D024N114 is built into a robust Frame D chassis, optimized for heat dissipation and durability. While the drive offers significant power density, it maintains a manageable physical profile suitable for standard industrial enclosures. The unit has a net weight of approximately 3.9 kg (8.6 lbs), facilitating easier installation and maintenance within control panels. Its IP20 rating ensures protection against solid objects larger than 12.5mm, making it ideal for clean, dry industrial environments.

Technical Specifications

Advanced Control Features

The PowerFlex 523 series excels in precision with its Sensorless Vector Control (SVC), providing ±0.1% speed regulation across a 100:1 range. For specialized motors, the 25A-D024N114 supports Permanent Magnet (PM) motors up to 10 HP. Additionally, the SVC Economizer mode automatically adjusts the output voltage to optimize motor efficiency based on the load. With independently programmable acceleration and deceleration times ranging from 0 to 600 seconds (in 0.01s increments), users have granular control over machinery startup and shutdown cycles.

Technical FAQs

Q1: What is the benefit of the SVC Economizer feature?
A1: The SVC Economizer reduces energy consumption by dynamically lowering the voltage applied to the motor during periods of low demand or constant speed, without sacrificing performance.

Q2: Can this drive be mounted side-by-side?
A2: Yes, the PowerFlex 520-series features a unique modular design that allows for "Zero-Stacking" or side-by-side mounting to save valuable panel space, provided ambient temperature limits are observed.

Q3: Does the 25A-D024N114 include an internal EMC filter?
A3: This specific model is a non-filtered version (indicated by the 'N' in the part number). If EMC compliance is required for your installation, an external filter may be necessary.
