Allen-Bradley 80026-044-06-R PowerFlex 7000 IGDPS Power Supply Module

Description

The Allen-Bradley 80026-044-06-R is an Isolated Gate Driver Power Supply (IGDPS) switching power supply module designed for medium voltage industrial drives. Specifically engineered for integration within the PowerFlex 7000 medium voltage AC drive platform, the 80026-044-06-R serves as a specialized power delivery unit that converts DC link or bus voltages into multiple isolated outputs. This configuration is optimized to drive Symmetrical Gate-Commutated Thyristors (SGCT) or Integrated Gate-Commutated Thyristors (IGCT) in high-power converter and inverter configurations. By providing independent, low-noise power paths, the module isolates gate control circuitry from high-voltage main power structures, minimizing electromagnetic interference (EMI) and preventing cross-channel fault propagation across the gate driver sub-assemblies.

Features

• Multi-channel electrical isolation delivering power across 6 distinct outputs to mitigate cross-channel interference
• High-current capacity tailored to handle the transient peak power requirements of medium voltage thyristor gating
• Ruggedized component layout for reliable deployment within industrial drive enclosures and high-vibration power structures
• Direct mechanical and electrical compatibility with the standard PowerFlex 7000 component chassis layouts

Applications

• Gate driver power distribution in PowerFlex 7000 medium voltage AC drives
• Isolated power provisioning for SGCT and IGCT power semiconductors
• High-power inverter and rectifier bridge power subsystem configurations

Installation Guidelines

• Enclosure Isolation: Ensure the main power feed to the PowerFlex 7000 drive is locked out and all internal DC link inductors and capacitors are fully discharged before initiating installation.
• Surface Mount Torque: Secure the module to the internal panel or chassis using specified surface-mount fasteners to prevent mechanical stress under continuous operational vibrations.
• Cable Routing: Routinely separate low-voltage gate driver output cabling from high-voltage motor or line cables to maintain clean signal delivery paths and preserve low noise thresholds.
• Thermal Management: Ensure surrounding airflow channels remain unobstructed to maintain steady convective cooling across the module's power electronics under full rated load.
