Overview
The Allen-Bradley 25B-D4P0N104 is a PowerFlex 525 AC drive engineered for 480 VAC 3-phase industrial applications. This variable frequency drive delivers 2 HP (1.5 kW) nominal output and 4 amperes, supporting both normal and heavy-duty motor control modes. Built by Rockwell Automation, the drive features embedded EtherNet/IP with safety-rated torque control and is housed in a compact Frame A IP20 NEMA open-type enclosure, making it suitable for panel-mounted installations.
Key Features
- Embedded EtherNet/IP & Safety Functions: Native industrial Ethernet connectivity with SIL 2 / Category 3 safety-rated torque off control
- Wide Input Voltage Range: Accepts 3-phase input voltages from 380 to 480 volts AC
- Flexible Control Modes: Sensorless vector, closed-loop vector, and permanent magnet motor control with integrated braking IGBT
- Standard Communication Interfaces: Uses Ethernet and USB port for communication
- Multiple Protocol Support: Supporting Protocol for DeviceNet, EtherNet/IP, MODBUS, Other Bus Systems, PROFIBUS
- IP20 NEMA Rated Enclosure: Uses IP20 NEMA enclosure for mounting in standard industrial control cabinets
Technical Specifications
The drive operates at 50–60 Hz input frequency and includes a standard interface module and brake option for straightforward integration into existing automation systems.
Typical Applications
The 25B-D4P0N104 is ideal for process and motion control applications in manufacturing, material handling, HVAC, pump and fan drives, and other general-purpose variable speed motor applications requiring 2 HP induction or permanent magnet motors on 480 VAC 3-phase supplies.
Compatibility & Replacements
As a PowerFlex 525 Frame A drive, the 25B-D4P0N104 offers backward compatibility with legacy PowerFlex 525 installations and serves as a direct replacement for worn or failed units. Rockwell Automation supports this model with repair services and access to firmware updates through the Technical Documentation Center.
