FAQs
When deploying the DK 7979.434 in VX IT frames, use the zero-U mounting option to maximize space efficiency. The enclosure supports a 2,200 mm or greater footprint and the PDU’s 2,095 mm length aligns with VX IT system rails, enabling tool-free mounting in many configurations. Ensure cable routing maintains 3 m supply length and proper earthing to meet EMC requirements.
The PDU provides energy measurement, switching and monitoring on each individual output slot, with a network interface for centralized visibility. Monitoring includes status indicators and the ability to integrate with CAN bus sensors for ambient data. This allows precise load profiling, fault detection, and energy accounting per circuit in data centers and server rooms.
Yes. The DK 7979.434 PDU complies with CE marking and EN 62368-1 safety standards, reflecting adherence to rigorous European safety and EMC requirements for IT equipment. The EMC Directive 2014/30/EU guidance is also applicable, ensuring reliable operation in networked, high-density IT environments.
The PDU includes a PoE-enabled web server and a fully redundant Ethernet interface, allowing secure HTTP/HTTPS access, NTP time synchronization, and SSH/Telnet for management. This enables remote configuration, event logging, and energy data collection across multiple racks without direct on-site visits, improving incident response and operational uptime.
ROI benefits come from improved energy visibility, reduced outages due to advanced protection features, and streamlined maintenance via replaceable controllers and easy access to per-outlet data. Maintenance considerations include periodic firmware/MCU checks, assessing the optional overvoltage protection and CAN sensors for ambient monitoring, and ensuring compatibility with VX IT enclosure frames for future scalability.
