Allen-Bradley PowerFlex 523 AC Drive 1.5 kW 2 HP | 25A-D4P0N104

Hardware Performance Overview

The 25A-D4P0N104 (Catalog Number: 25A-D4P0N104) is a compact and versatile Variable Frequency Drive (VFD) within the PowerFlex 523 series, optimized for standalone machine-level control. This Frame A drive is engineered to deliver 2.0 HP (1.5 kW) of output power for three-phase motor applications. Featuring an innovative modular design, the power module and control core can be separated, streamlining installation and reducing downtime during maintenance. Its standard IP20 NEMA/Open Type enclosure supports DIN-rail or panel mounting, with "Zero Stacking" capability to maximize enclosure space efficiency.

Key Operational Features

The PowerFlex 523 series prioritizes flexibility and precision for mechanical systems:

• PointStop Technology: Provides consistent and predictable stopping positions for loads without the need for an external encoder.

• AppView and CustomView: Pre-configured parameter groups for specific applications (conveyors, fans, pumps) to accelerate commissioning.

• Programming: Supports the USB-based configuration tool for offline programming and the MainsFree power option for configuration without high-voltage input.

Technical Integration FAQ

Does this drive support Safe Torque Off (STO)?The standard 25A-D4P0N104 (PowerFlex 523) does not include integrated STO. For safety-integrated applications requiring SIL2/PLd, the PowerFlex 525 (25B series) is the recommended alternative.

What is the maximum ambient temperature for Zero Stacking?The drive can be mounted side-by-side without clearance at ambient temperatures up to 45°C. For temperatures reaching 50°C, a minimum clearance or the use of a fan kit is recommended to maintain optimal thermal performance.
