Product description
DK PDU managed, high-end power distribution incl. energy measurement, switching and monitoring functions per output slot, with network interface and display, WLD: 44x1095x70 mm, IEC 60 320: 12x C13 + 4x C19
Per-output energy measurement and monitoring deliver precise visibility into energy use for each outlet, enabling targeted load balancing and waste reduction. This translates to measurable savings on monthly electricity bills and more predictable rack performance in dense deployments. Network interface with a PoE-enabled web server and rotatable display enables remote monitoring without on-site visits, reducing management overhead and accelerating incident response. High-density outlets—12 x C13 and 4 x C19 on a compact 44x1095x70 mm enclosure, 230 V and 32 A rating—support scalable IT power distribution while maintaining cable hygiene and serviceability. Redundancy and sensor integration provide a fully redundant Ethernet interface plus CAN bus ambient sensors, improving reliability and environmental awareness across data centers. Optional protections and compliance features, including Type 3 overvoltage protection with interchangeable arresters and residual current measurement, help meet regulatory requirements and reduce risk. Installation advantages include zero-U mounting compatibility with VX IT frames and configurable mounting options for 19" racks, enabling fast deployment with minimal tools.

FAQs
The DK 7979.413 PDU is designed for VX IT racks and related VX IT enclosure frames. It supports zero-U vertical mounting and fits VX IT frame widths and mounting rails specified by Rittal, ensuring a clean integration with minimal tools. The 44 mm width and 1,095 mm length are tailored for high-density IT enclosure deployments.
It offers per-output energy measurement and monitoring for 12 C13 and 4 C19 outlets, plus an integrated network interface and PoE-enabled web server for remote access. This enables real-time power visibility, outlet-level fault detection, and centralized dashboards, which translate to targeted energy savings and improved uptime management.
The unit complies with EMC Directive 2014/30/EU and EN 62368-1, aligning with essential electrical safety and electromagnetic compatibility requirements for IT infrastructure. Optional protections and environmental monitoring features further support regulatory compliance and safer operation in enterprise data centers.
Yes. The PDU supports optional monitoring through CMC III CAN bus sensors for ambient conditions and can connect multiple sensor units (up to two RJ45 sensor ports). This enables environmental awareness, early fault detection, and improved preventive maintenance in data centers.
Plan for a VX IT deployment with zero-U mounting where possible to save rack space and simplify installation. Leverage the rotatable display for ease of service access, the 3 m CEE supply cable for flexible placement, and the 12x C13 / 4x C19 outlets to consolidate power distribution, reducing wiring complexity and improving mean time to repair (MTTR).
