Quick Summary
Rittal 7979230 PDU metered provides per-phase energy measurement for IT rack power distribution. In dense compute environments, lack of visibility into energy usage drives higher operating costs and can compromise uptime. The unit is certified under EMC Directive 2014/30/EU and EN 62368-1 for safety and interoperability, with a built-in web server for secure configuration and monitoring. This solution enables per-infeed or per-phase measurement, supporting scalable energy management across multi-rack deployments. Optional USB mass configuration and plug‑and‑play integration with VX IT frames simplify deployment and ongoing maintenance, delivering clearer insights for IT and facilities teams and driving improved cost control.

FAQs
Installs in VX IT frames supporting zero-U mounting. Align the PDU length (845 mm) with the frame, attach using the included installation parts, and connect the 3 m CEE cable to the incoming 400 V supply. Use the rotatable display to position the interface for optimal readability, then configure the unit via the USB port or web interface. The compact design and standard 9x C19 sockets simplify wiring and maintenance in tight rack spaces.
The PDU delivers per-phase or infeed energy measurement, enabling visibility of power usage across all 3 phases. With a 16 A rating and a 400 V supply, it reports real-time power, energy, and associated metering data through its web interface and USB logging for audit trails. This supports chargeback, capacity planning, and compliance reporting for IT environments.
Yes. The DK 7979.230 PDU metered is designed for 3-phase 400 V (AC) IT installations, with a 16 A maximum current per circuit and a 3P infeed configuration. It uses CEE connections and includes a 3 m supply cable, making it suitable for standard data center and edge rack deployments that require centralized energy monitoring.
The unit complies with EMC Directive 2014/30/EU and EN 62368-1 safety standards. It supports secure web-based protocols (HTTP/HTTPS/SSL, SSH, Telnet, NTP) and includes configuration via USB, ensuring regulatory alignment and robust interoperability in modern IT environments.
By delivering per-phase energy visibility and centralized monitoring, the PDU enables precise usage analytics, reduces energy waste, improves uptime through better fault detection, and simplifies chargeback or capacity planning. Its compact form factor, VX IT compatibility, and easy remote management reduce deployment time and total cost of ownership for data centers and enterprise IT environments.
