Product description
DK PDU switched, compact basic power distribution incl. energy measurement per phase, individually switchable output slots, with network interface and display, WLD: 44x1695x70 mm, IEC 60 320: 42x C13
Energy measurement per phase with a rotatable display provides immediate visibility into power usage, enabling accurate accounting, chargeback capability, and load balancing in dense IT deployments. Business impact: reduced energy waste and improved capacity planning; Application: IT racks in data centers needing per-phase insight. 42 x C13 sockets deliver high-density power distribution within a compact footprint, simplifying cabling and reducing the number of PDUs required on large racks. Business impact: lower CAPEX per rack and cleaner installations; Application: server and storage cabinets. Fully redundant Ethernet interface with 10/100/1000 Mbps (2x RJ45, one with PoE) enables secure remote monitoring and web-based management, improving uptime and operator control. Business impact: faster fault detection and reduced on-site visits; Application: data centers and edge deployments. Zero-U mounting compatibility with VX IT frames and a rotatable, replaceable control unit streamline installation and maintenance, saving time during rack-outages and upgrades. Business impact: easier scale-out and lower maintenance windows; Application: IT room upgrades and modular architectures. Overvoltage protection options, residual current measurement (type B) per infeed/phase, and CAN bus sensor connectivity provide enhanced safety and environmental monitoring. Business impact: safer operation, regulatory compliance, and proactive risk management; Application: mission-critical IT environments. Emergency power sequencing and PoE-powered PDU web server support simplify power-down procedures and ensure continuous monitoring, reducing the risk of unexpected outages. Business impact: improved reliability, lower maintenance overhead, and better IT service continuity; Application: resilient data-center operations.

FAQs
Install the DK 7979.342 PDU switched by mounting it in the VX IT rack's zero-U space, connect the 3 m CEE feed, and route the 42 C13 outputs to devices. The rotatable display simplifies alignment during setup, and the controller is replaceable to minimize downtime during service. Appropriate cable management and labeling are recommended for scalable deployments.
Key specs include a 400 V AC rated voltage, a maximum 16 A current, and an overall power capacity of 11 kW. It provides 42 sockets of type C13, uses a 3 m connection cable, and supports three-phase infeeds. The enclosure connects via a CEE input and offers an Ethernet interface for management, with EMC and safety compliance.
Yes. The DK 7979.342 PDU switched is designed for vertical mounting in VX IT enclosures, occupying zero-U space and enabling tool-free placement. This compatibility simplifies installation in existing VX IT frames and reduces rack footprint, making it ideal for dense data-center environments where space is at a premium.
The unit provides a fully redundant Ethernet interface with 10/100/1000 Mbps (two RJ45 ports, one with PoE) and supports standard web protocols including HTTP, HTTPS, SSL, SSH, Telnet, and NTP. These features enable secure remote monitoring, controlled access, and reliable time synchronization for compliant IT operations.
Per-phase energy measurement enables precise usage analytics and chargeback, while remote monitoring reduces on-site visits and unplanned outages. The rotatable display and replaceable controller lower maintenance costs, and the high-density 42 x C13 output count lowers CAPEX per rack. Together, these capabilities support energy efficiency programs and faster fault resolution in mission-critical IT spaces.
