Product description
DK PDU managed, high-end power distribution incl. energy measurement, switching and monitoring functions per output slot, with network interface and display, WHD: 450x44x144 mm; IEC 60 320: 6x C13
Energy measurement per output slot enables precise cost allocation and load trending, reducing waste and optimizing capacity planning. Business impact: lower energy bills and better budgeting for IT loads. Application: data centers and enterprise server rooms needing per-outlet visibility. The fully redundant Ethernet interface with PoE supports reliable, remote monitoring and seamless integration into existing network architectures. This translates to faster fault detection and simpler maintenance, lowering mean time to repair. Business impact: higher uptime and reduced service windows. Application: rack-scale deployments with centralized management. The compact 19" design (450x44x144 mm) and zero-U mounting option allow vertical installation in VX IT racks, saving valuable rack space. Business impact: denser computing layouts and easier cabling. Application: VX IT and TS IT rack ecosystems. The rotatable display/controller unit (180°) is serviceable and replaceable, reducing downtime during maintenance. Business impact: improved lifecycle management and lower spare parts costs. Application: fielded IT environments requiring easy, tool-free servicing. The PDU supports C13 sockets (6x) with 230 V, 16 A rating and IEC C20 inlet, ensuring compatibility with standard IT power architectures. Business impact: straightforward sourcing and predictable performance. Application: new or upgrade IT rack builds. Optional CMC III CAN bus sensors enable ambient monitoring, extending visibility to environment conditions. Business impact: proactive environmental control and compliance support. Application: data centers with strict ambient monitoring requirements. Overall, the DK PDU aligns with IT managers’ needs for scalable, compliant, and monitorable power distribution.

FAQs
The DK 7979.402 PDU is designed for VX IT enclosures and 19" mounting. It can be attached in the zero-U space of compatible VX IT frames, saving rack space and simplifying cabling. You will need a customer-supplied IEC C20 inlet cable; the PDU itself ships as a single unit with six C13 outlets and a rotatable display for easy setup and monitoring.
This PDU complies with the EMC Directive 2014/30/EU and EN 62368-1 safety standards, ensuring regulatory compliance and reliable performance in networked IT environments. It also supports standard IT power infrastructure with a 230 V supply and a 16 A maximum current rating, aligning with common rack architectures.
Yes. The DK PDU provides energy measurement and monitoring per output slot, enabling precise usage reporting and cost allocation. It is designed to integrate with a Web server interface, allowing remote access to per-outlet data and fault indicators for proactive management.
Compatibility is built into the design for VX IT enclosure frames and 19" mounting. The unit supports vertical mounting in zero-U spaces and includes mounting provisions for VX IT frames with adjustable enclosure width, offering flexibility for space-constrained data centers and edge deployments.
The per-outlet energy visibility, remote management via a secured interface, and automated power sequencing translate into reduced energy waste, faster fault isolation, and lower operational downtime. Combined with regulatory compliance and lifecycle efficiency, this can shorten payback periods and improve total cost of ownership for IT power infrastructure.
