FAQs
Install the DK 7979.235 PDU metered in a VX IT enclosure frame, ensuring alignment with the enclosure's height (≥ 1,200 mm) and mounting angles. Connect the 3 m CEE cable to a 400 V three‑phase supply. Use the rotatable display for convenient orientation and leverage the USB-A port for initial mass configuration and firmware updates before commissioning.
The PDU operates at 400 V AC with a maximum current of 16 A and a power capacity of 11 kW. It provides 18 C13 sockets and 3 C19 sockets, arranged for IT rack density. The unit uses a 3‑phase infeed and includes a 3 m connection cable with a CEE connector, suitable for standard data center electrical infrastructure.
Yes. It features per‑phase energy measurement, infeed energy monitoring, and a network interface plus mass configuration via USB. Management protocols include HTTP/HTTPS and SSH, with data logging and time synchronization via NTP. This enables energy transparency, load profiling, and proactive capacity planning for data center IT racks.
This PDU complies with EMC Directive 2014/30/EU and EN 62368‑1 safety standards, with CE marking for interoperability and safety. These certifications ensure regulatory compliance, electrical safety, and compatibility with modern IT equipment, reducing risk during deployment and facilitating audit-ready documentation for IT infrastructure projects.
