Product Introduction
When your Allen-Bradley PowerFlex 7000 medium-voltage AC drive system needs a highly reliable dedicated internal power distribution unit to stably supply power to all internal control circuits and power components, this module acts as the system’s core power hub.
It is a flagship industrial-grade switching power supply module from Allen-Bradley 80026-044-06-R series, specially designed for PowerFlex 7000 medium-voltage AC drive scenarios. It has a wide DC input voltage range of 24-60VDC, which can adapt to complex industrial power supply fluctuation environments. It integrates 6 independent isolated secondary outputs, each capable of stably outputting 3A@20VDC, which can independently supply power to different functional areas inside the drive, avoiding mutual interference between power domains. Its 3000V reinforced electrical isolation design can effectively block the high-voltage electrical noise inside the medium-voltage drive from spreading to the low-voltage control side, greatly improving the overall electrical safety of the system. Its industrial-grade rugged mechanical design can withstand 5g operating shock, and it is equipped with built-in thermal protection and overcurrent protection mechanisms, which can automatically trigger protection actions when the internal temperature is too high or the load is overloaded, avoiding permanent burnout of the power module. It has a compact size of 118 × 35 × 87 mm and a net weight of only 0.20kg, which can be easily installed in the limited internal space of the PowerFlex 7000 medium-voltage drive. It has UL and CSA safety certifications, making it a core replacement part for Allen-Bradley PowerFlex 7000 medium-voltage drive system maintenance and retrofit projects in large metallurgy, mining and petrochemical industries.

Field Application & Technical Pitfalls
Critical Industrial Scenarios
- **Large Metallurgical Plant Main Medium-Voltage Drive Internal Power Supply: Acts as the core power distribution unit for metallurgical plant PowerFlex 7000 medium-voltage drives, realizing stable and continuous multi-channel power supply for all internal control circuits, ensuring the medium-voltage speed regulation system will not lose power unexpectedly during long-term operation.
- **Large Mining Conveyor Medium-Voltage Frequency Converter Power Distribution: Delivers reliable high-performance power supply performance for mining site PowerFlex 7000 medium-voltage drives, adapting to long-term high-vibration industrial environments, meeting the high-reliability uninterrupted power supply requirements of mining conveyor speed control systems.
- **Large Petrochemical Plant Pump Medium-Voltage Drive Redundant Power Backup: Adapts to strict continuous operation industrial environments, providing stable uninterrupted power distribution support for the petrochemical plant PowerFlex 7000 medium-voltage drive automation system.
Non-Negotiable Technical Pitfalls
- ⚠️ Bold Warning 1: Never arbitrarily connect the input terminal to a DC power supply that exceeds the 60VDC maximum voltage limit. The third power channel will experience overvoltage that causes the internal power circuit to burn out.
- ⚠️ Bold Warning 2: Skipping the pre-commissioning full 24-hour 6-channel full-load continuous power distribution test will leave you with hidden drive system power loss risks. This module must confirm the full multi-channel power output performance fully meets PowerFlex 7000 drive specifications before putting into operation.
- ⚠️ Bold Warning 3: Do not arbitrarily use non-matching non-industrial-grade DC power cables for power connection. Improper cable performance will cause the power supply to be interfered and trigger frequent drive system power supply alarms.
A large metallurgical plant maintenance team once swapped an Allen-Bradley 80026-044-06-R module and skipped the full 6-channel load test. The hidden power wiring configuration error caused the medium-voltage drive internal control power supply to be interrupted, resulting in the main production line being stopped for 1 hour.
Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against Rockwell Automation’s official PowerFlex part registry, confirm the part number 80026-044-06-R matches the factory label, and inspect no damage or oxidation on all power terminals and backplane connectors.
- Live Rig Testing: Power the unit in a calibrated Allen-Bradley PowerFlex 7000 medium-voltage drive system test bench, simulate full 6-channel full-load continuous power distribution scenarios, and confirm full 2-hour continuous stable operation.
- Parameter Testing: Verify the 24-60VDC full-range power input performance meets factory specifications, confirm the 3000V isolation performance meets industrial medium-voltage drive power supply standards, and validate all on-board status indicators work properly.
- Final QA & Packaging: Seal the tested module in a static-shielding anti-static bag, attach a unique QC passed serial label, and nest it in foam padding inside a rigid industrial shipping carton.
Frequently Asked Questions (FAQ)
- Can I hot-swap this module while the PowerFlex 7000 drive is running? No. You must first confirm that the redundant power supply path is operating normally and the drive is in a safe shutdown state, then perform the replacement operation after cutting off the module power, otherwise you will trigger unexpected drive system power loss risks.
- What exact systems is this module compatible with? It works natively with Allen-Bradley PowerFlex 7000 medium-voltage AC drive platforms, and can seamlessly connect with all standard PowerFlex 7000 series internal control circuits, no custom adaptation is required.
- How long is the standard warranty for this new surplus unit? 12 months from delivery. It covers all manufacturing defects, but does not extend to units damaged by miswiring, overvoltage power input, or improper power load configuration in the field.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine Allen-Bradley 80026-044-06-R modules have a laser-etched part number on the PCB, not a printed sticker. Clone units almost always fail the full 2-hour 6-channel full-load power distribution stability test.
- What is the typical lead time for shipment? In-stock units ship within 48 hours. If you require official Rockwell factory power supply module performance test documentation, add 2 extra business days to the turnaround window.
- Can this module replace the older Allen-Bradley legacy PowerFlex 7000 power supply module? Well, technically it fits the same standard installation footprint, but you must confirm the PowerFlex 7000 drive system firmware version fully supports the module before replacement to ensure 100% system compatibility.
