Main Features and Advantages
The Allen-Bradley 80026-044-06 delivers a combination of multi-output flexibility, robust isolation, and environmental resilience that addresses the power supply requirements of high-voltage drive and IGCT applications. Its design emphasizes dependable performance in the most demanding industrial settings.
Multi-Output Architecture for System Flexibility: The Allen-Bradley 80026-044-06 provides seven total output rails from a single module—a 50 VDC main output at 10 A plus six secondary outputs at 20 VDC and 3 A each . This configuration eliminates the need for multiple discrete power supplies in drive systems that require several isolated voltage levels for gate driver circuits, control electronics, and auxiliary functions. The Allen-Bradley 80026-044-06 simplifies cabinet wiring and reduces component count while maintaining clean separation between power domains.
High Isolation for Safety and Noise Immunity: The Allen-Bradley 80026-044-06 features a 3000 VDC isolation rating, providing a substantial safety barrier between the input supply and all output circuits . This isolation is essential in drive applications where the power supply may interface with high-voltage bus circuits, protecting control electronics from fault propagation and ensuring personnel safety during maintenance. The isolation also contributes to noise immunity by preventing ground loops and common-mode interference from affecting sensitive control signals.
Wide Input Tolerance for Global Compatibility: The Allen-Bradley 80026-044-06 accepts input voltages from 24 to 60 VDC, accommodating the DC bus voltage variations commonly found in industrial drive systems . This wide input range provides design flexibility and ensures stable output regulation even when the source voltage fluctuates due to load changes or distribution losses. The module’s switching technology delivers high conversion efficiency, minimizing heat generation and reducing the thermal burden on enclosed cabinets.
Environmental Resilience for Harsh Installations: The Allen-Bradley 80026-044-06 is specified to withstand 5 g shock and vibration from 5 to 32 Hz, making it suitable for installations where mechanical stress is a concern . Its operating humidity range of 5 to 95% non-condensing accommodates the varied environmental conditions found in industrial facilities, from dry control rooms to humid process areas. The module‘s protection features—including overvoltage and short-circuit protection along with EMI filtering—further enhance its reliability by preventing damage from common electrical disturbances .
