Allen Bradley 25B-D2P3N114 PowerFlex 525 0.75kW (1Hp) AC Drive

Allen-Bradley 25B-D2P3N114 PowerFlex 525 AC Drive

The Allen-Bradley 25B-D2P3N114 is a PowerFlex 525 adjustable frequency AC drive rated at 0.75 kW (1 HP). Designed for compact motor control applications, it combines integrated EtherNet/IP communication, embedded Safe Torque-Off functionality, and a modular architecture within a Frame A enclosure. The drive supports both normal-duty and heavy-duty operation and is suitable for variable speed control of three-phase AC motors.

Product Specifications

Motor Control Capabilities

The PowerFlex 525 series is designed to provide variable frequency and voltage control for three-phase induction motors. By adjusting output frequency and voltage, the drive enables accurate motor speed regulation across a wide operating range.

The 0.75 kW rating makes this model suitable for small motor applications requiring reliable speed control, acceleration management, and deceleration control.

Integrated Communication

Embedded EtherNet/IP communication is included as a standard feature, allowing the drive to be connected directly to Rockwell Automation control architectures without requiring an additional communication module.

This capability supports parameter configuration, diagnostics, status monitoring, and control integration through EtherNet/IP networks.

Safety Features

The integrated Safe Torque-Off (STO) function provides a safety mechanism that prevents torque-producing energy from reaching the motor without disconnecting power from the drive itself.

The STO function is designed to support machine safety systems and carries safety ratings up to SIL 2 and Performance Level d (PL d) when implemented according to applicable safety requirements.

Compact Design

The drive is supplied in a Frame A, IP20 open-type enclosure, allowing installation inside properly protected control cabinets. Its modular design simplifies expansion and maintenance while reducing panel space requirements.

An integral EMC filter is included to assist with electromagnetic compatibility requirements, and the built-in brake IGBT supports applications requiring dynamic braking capability with an external braking resistor.

Application Considerations

The 25B-D2P3N114 supports both normal-duty and heavy-duty ratings at 0.75 kW (1 HP). Proper drive sizing should be based on motor full-load current, overload requirements, and application duty cycle.

Selection of braking components, network configuration, and motor protection settings should be verified during system design and commissioning.

Frequently Asked Questions

Q: What supply voltage is required for the 25B-D2P3N114?

A: This drive is designed for a 380-480 VAC three-phase supply at 50/60 Hz.

Q: Does the drive include EtherNet/IP communication?

A: Yes. Embedded EtherNet/IP communication is provided as a standard feature and does not require a separate communication module.

Q: Is a braking transistor included?

A: Yes. The drive includes an integral brake IGBT, allowing connection of an external braking resistor where application requirements demand dynamic braking.
