Product Introduction
The Allen-Bradley 25B-E012N104 PowerFlex 525 AC Drive is an adjustable frequency drive designed for precise speed and torque control of industrial AC motors. As part of the PowerFlex 525 family, the Allen-Bradley 25B-E012N104 replaces older generation drives with advanced features and higher efficiency. Operating on an input voltage of 446–660 VAC three-phase, this drive delivers a programmable output frequency from 0 to 500 Hz and a continuous output current of 12.0 A (10 HP / 7.5 kW). Built for demanding environments, the 25B-E012N104 offers a robust IP20/NEMA open-type enclosure and supports both panel mount and DIN rail installation.

The Allen-Bradley 25B-E012N104 achieves 97.5% efficiency, reducing energy losses compared to older drives. Its embedded I/O includes seven discrete inputs, one normally open and one normally closed contact, two digital/optocoupler outputs, two analog inputs (0–10 VDC or 0–20 mA), and one analog output (0–10 VDC or 0–20 mA). The drive supports zero stacking for space-saving installations.
Compatibility & Integration
The Allen-Bradley 25B-E012N104 features a built-in EtherNet/IP port alongside RS485, enabling seamless integration with Logix controllers using add-on instructions. This communication interface allows dynamic parameter control and remote configuration. The drive also supports standalone PI control for simple closed-loop applications. Its standard Human Interface Module (HIM) facilitates local setup, while remote operation can be managed via hardwired I/O or network commands.
Installation & Setup Guidance
Mount the Allen-Bradley 25B-E012N104 on a panel or DIN rail using the provided frame C mounting slots. Ensure the enclosure is placed in a clean, dry environment free from liquids and fine particles, as the IP20 rating protects only against solid objects larger than 12.5 mm. Connect input power (446–660 VAC, three-phase) to the designated terminals per the wiring diagram. Configure the drive using the standard HIM or via EtherNet/IP using Rockwell Automation’s software. Program accel/decel times and stop modes to match your motor and load requirements. For zero stacking, ensure proper airflow between drives.
Selection Guide & Purchasing Advice
When selecting the Allen-Bradley 25B-E012N104 for your facility, verify that the input voltage and output current match your motor specifications. The drive is ideal for replacing older PowerFlex 4, PowerFlex 40, or third-party drives in conveyor, pump, fan, and compressor applications.
