AH220A Use Case
High-Availability Data Center Core Switch Power Redundancy
In hyperscale and enterprise data centers, network architects deploy the AH220A-MSL4048/8048/8096 redundant power supply (PL=3C) in dual-feed core switches to guarantee uninterrupted 48 V DC power. By hot-swapping failed modules without downtime, IT teams maintain continuous service-level agreements (SLAs) and streamline maintenance windows. The outcome is 99.999% network availability, lower mean time to repair (MTTR), and robust fault tolerance under peak load.
Industrial Automation 24/7 Uptime Assurance
Manufacturing plants implement the AH220A-MSL4048/8048/8096 redundant power supply in PLC racks and SCADA controllers to secure constant 48 V DC input across critical production lines. The module’s PL=3C rating and hot-swap capability enable field engineers to replace faulty units during live operations, preventing unplanned stoppages. This delivers measurable OEE improvements, reduced downtime costs, and enhanced operational safety in high-volume industrial environments.
Telecom Base Station DC Power Continuity
Telecom operators integrate the AH220A-MSL4048/8048/8096 redundant power supply into 48 V DC remote radio units (RRUs) and baseband cabinets to ensure seamless backup power during grid fluctuations. The dual-module configuration automatically load-shares and isolates faults, preserving voice and data traffic. As a result, providers achieve carrier-grade reliability, simplify on-site servicing, and meet stringent uptime mandates for 5G and legacy networks.
