Allen-Bradley 80026-524-01 PowerFlex 7000 Power Supply

Allen-Bradley 80026-524-01 AC/DC Power Supply

The Allen-Bradley 80026-524-01, also cataloged as the 80026-524-01-R Power Supply Module, operates as a dedicated hardware component for 56 VDC regulated voltage execution within PowerFlex 7000 drive systems.

Hardware Specifications

Allen-Bradley Industrial Control Characteristics

The 80026-524-01 module leverages deterministic AC-to-DC conversion to maintain stable voltage rails for high-power drive logic. The hardware architecture utilizes I/O density scaling via modular form factors, allowing seamless integration into existing control cabinets alongside other PowerFlex components. Proactive firmware flash compatibility ensures that power regulation logic remains synchronized with the drive's internal communication protocols. Furthermore, the unit supports Profinet and EtherNet/IP deterministic networks by providing isolated 56 VDC power, preventing back-plane bus communication latency during heavy transient load demands. Integrated thermal heat sink dissipation profiles enable sustained peak current delivery even when the internal ambient temperature approaches its upper operating limit.

Frequently Asked Questions

Q: Does the power supply support hot-swapping in a multi-drive configuration?

A: The module is not designed for hot-swapping. Technicians must isolate the primary AC input and verify zero-energy states before disconnecting or replacing the unit to prevent damage to the drive's control logic.

Q: How is the 56 VDC output regulated during fluctuating AC input conditions?

A: The internal switching regulator utilizes pulse-width modulation (PWM) to maintain a steady 56 VDC output across the specified AC input voltage range, ensuring voltage stability for the drive's gate driver circuits.

Field Installation Guidelines

1. Safety Precautions: Verify that the main AC input disconnect is locked and tagged out. Discharge all residual high-voltage capacitors in the PowerFlex 7000 drive before touching internal terminals.
2. Mounting: Secure the power supply module to the cabinet backplane using the mounting holes provided. Ensure the convective air-cooling path is not obstructed by cable bundles or ductwork.
3. Wiring: Use appropriately rated gauge wire to connect the 230 VAC input and the 56 VDC output terminals. Tighten all screw terminals to the specified torque setting to minimize contact resistance.
4. Validation: After installation, perform a low-voltage test. Use a calibrated multimeter to verify the output voltage matches the 56 VDC nominal requirement before enabling the main drive enable signal.
