Why Choose the Rittal DK7979.238 PDU Metered?
The Rittal DK7979.238 is a high-performance three-phase metered power distribution unit (PDU) designed for reliable power distribution and energy monitoring in IT network and server racks. Part of the Rittal PDU metered range, it combines a high outlet density with integrated per-phase measurement, network connectivity and a local display for professional data centre and IT infrastructure applications.
Designed for a 16 A three-phase supply, the DK7979.238 provides a total of 30 IEC 60320 outlets, comprising 18 × C13 and 12 × C19 sockets. This combination supports the connection of a wide range of servers, switches, storage systems and other rack-mounted IT equipment from a single vertically installed power distribution unit.
The PDU is housed in a robust aluminium profile measuring approximately 44 mm wide × 1695 mm high × 70 mm deep. It is designed for vertical Zero-U installation and can be mounted tool-free in compatible Rittal VX IT and TS IT racks. Integrated energy measurement, a TFT display and network interfaces provide convenient monitoring of electrical consumption and operating conditions.

Reliable Metered Power Distribution for IT Infrastructure
The Rittal DK7979.238 combines rack-level power distribution with detailed electrical monitoring. Parameters such as voltage, current, frequency, power factor, active power, active energy and apparent power can be monitored, helping IT administrators understand power demand and identify potentially critical operating conditions within the rack.
Network interfaces and supported communication protocols enable the PDU to form part of a wider infrastructure monitoring system. Adjustable alarm thresholds, an integrated acoustic alarm and connectivity for compatible environmental sensors further enhance its suitability for data centres and other installations where power availability and environmental monitoring are critical.
