Product description
DK PDU switched, compact basic power distribution incl. energy measurement per phase, individually switchable output slots, with network interface and display, WLD: 44x1895x70 mm, IEC 60 320: 36x C13 + 6x C19
Per‑phase energy measurement with individually switchable outputs enables precise load management. This delivers actionable insights and reduces energy waste by identifying imbalance and overloads before they impact uptime. Use it in IT racks and data centers where per‑phase visibility informs capacity planning and green IT initiatives. High density capability: 400 V AC supply, 16 A max, 11 kW rating with 36 C13 and 6 C19 outlets. This supports modern server and networking gear while maintaining headroom for growth, improving energy efficiency and reducing risk of circuit trips. Ideal for VX IT enclosures and TS IT racks in enterprise data centers. Rotatable display/controller unit (180°) and replaceable module simplify installation and maintenance in confined rack spaces, cutting commissioning time and service downtime. It supports flexible positioning in tight cabinets and enables quick field replacement. Fully redundant Ethernet interface 10/100/1000 Mbps with two RJ45 ports and a PoE-capable port ensures robust remote management and network resilience. This enables reliable remote monitoring, alerting, and integration with monitoring systems and PDU web servers. Options include Type 3 overvoltage protection with interchangeable arresters, residual current measurement (type B), CAN bus sensors, and enclosure-color customization. These features enhance safety, electrical protection, and ambient monitoring while meeting regulatory expectations for data-center infrastructure. Mechanical compatibility with VX IT frames and 19" mounting rails supports straightforward integration into existing IT enclosures, reducing retrofit risk and aligning with standard rack footprints.

FAQs
The DK 7979.340 PDU supports zero‑U mounting in VX IT frames and TS IT racks, enabling deployment in tight spaces without tools. Compatibility with VX IT enclosure frames and standard 19" mounting rails simplifies integration, reduces installation time, and preserves valuable rack space while keeping power distribution and monitoring centralized.
This PDU operates at 400 V AC with a maximum current of 16 A and an 11 kW power rating. It provides 36 C13 and 6 C19 outlets across a 1,895 mm length, uses a 3‑phase infeed, and utilizes a CEE connection. A rotatable display, replaceable module, and a dual gigabit Ethernet interface with PoE support enhance remote management.
Per‑phase energy measurement delivers granular load data for each phase, enabling precise capacity planning and imbalance detection. Combined with individual outlet switching, it supports selective power downs during maintenance and audits, reducing energy waste and boosting uptime in critical data centers.
The DK 7979.340 PDU complies with EMC Directive 2014/30/EU and EN 62368‑1 safety standards, and carries CE certification for European deployment. These certifications assure regulatory compliance, safer operation, and compatibility with modern IT infrastructure.
Plan for a 1,895 mm length along the rack, with the 44 mm width and 70 mm height to fit VX IT or TS IT enclosures. Ensure a 3 m input cable and CEE connection are accessible, and leverage the redundant Ethernet interface for network resilience and remote monitoring integration.
