The Allen-Bradley PM3328B-6-1-3-E 80026-524-01, also cataloged as the PM3328B Power Supply, operates as a dedicated hardware component for AC-to-DC power conversion within PowerFlex 7000 medium-voltage drive systems. The unit accepts a single-phase 100-240 V AC input and delivers regulated 24 V DC output power for internal control electronics, communication assemblies, and drive auxiliary circuits.

Product Identification

The PM3328B-6-1-3-E 80026-524-01 is supplied as a complete power supply assembly for PowerFlex 7000 AC drive platforms. No official suffix decoding data is available in the provided documentation; therefore, the catalog number should be referenced exactly as specified during maintenance and replacement activities.

Technical Data

EtherNet/IP Infrastructure and Firmware Compatibility

Within PowerFlex 7000 drive architectures, stable operation depends on compatibility between power conversion hardware, drive firmware revisions, and associated control modules. During replacement activities, the PM3328B power supply should be verified against the installed drive firmware revision and control assembly documentation. Maintaining approved firmware combinations helps prevent startup faults, communication initialization delays, and controller diagnostic alarms.

Technical Questions

Q: Does the module require an external DC power source?
A: No. The unit converts incoming 100-240 V AC power into regulated 24 V DC output for connected drive subsystems.

Q: Can the power supply be replaced while the drive remains energized?
A: Power isolation procedures should be completed before removal or installation. Follow the drive manufacturer's lockout and discharge requirements.

Q: What output voltage is provided by the unit?
A: The power supply provides a nominal 24 V DC output.

Q: What environmental conditions are supported during operation?
A: The specified operating temperature range is -25 deg C to +70 deg C with 5-95% non-condensing relative humidity.

Q: Is the unit intended for direct field mounting?
A: Installation location depends on the PowerFlex 7000 enclosure configuration. The module is normally installed within the drive cabinet according to manufacturer documentation.

Installation Recommendations

• Verify input voltage availability before energizing the power supply.

• Ensure all protective earth connections are properly terminated.

• Route power conductors separately from low-level communication wiring where possible.

• Inspect cabinet ventilation paths to prevent excessive thermal accumulation.

• Confirm terminal tightness according to applicable maintenance procedures.

• Use anti-static handling practices when servicing adjacent control electronics.

• Inspect connectors and mounting hardware for mechanical damage before installation.

• Verify correct catalog number matching prior to replacement activities.
