Why Choose the Rittal DK 7979.342 PDU Switched?
The Rittal DK 7979.342 is an intelligent three-phase switched Power Distribution Unit (PDU) designed for high-end power distribution, monitoring and remote outlet control within IT racks, server enclosures and data centre infrastructure. As part of the Rittal DK PDU switched series, it combines 42 IEC 60320 C13 outlets with per-phase energy measurement, individually switchable outputs, network connectivity and an integrated display.
Designed for professional IT environments, the DK 7979.342 allows every output slot to be switched individually while monitoring electrical consumption at the infeed and per phase. Programmable switching behaviour, adjustable warning and alarm thresholds and configurable start-up states provide administrators with precise control over connected equipment. Sequential outlet activation following voltage recovery also helps reduce simultaneous inrush-current peaks.
Operating from a 400 V AC, 16 A three-phase supply, the PDU provides a rated power capacity of 11 kW. Its 42 C13 outlets are arranged as 14 outlets per phase, while the slim 44 × 1695 × 70 mm anodised aluminium housing supports space-efficient Zero-U installation in compatible Rittal VX IT and TS IT racks.

Intelligent Three-Phase Power Control for IT Racks
Switched PDUs such as the Rittal DK 7979.342 provide significantly greater control than conventional rack power strips. Each of the 42 C13 outputs can be switched individually, enabling administrators to remotely power-cycle connected servers and network devices, create controlled switching sequences and manage equipment power states without physical access to the rack.
Per-phase energy measurement provides visibility into three-phase rack loading, while network connectivity enables integration with data centre and infrastructure management systems. Programmable switching, configurable thresholds, alarm functions and support for up to 16 CAN bus sensors make the DK 7979.342 a comprehensive power management solution for high-density and mission-critical IT installations.
Typical Applications
- High-density data centre server racks.
- Remote switching and power cycling of servers.
- Network and telecommunications equipment.
- Three-phase rack-level power distribution.
- Per-phase energy and load monitoring.
- Remote IT infrastructure management.
- Rittal VX IT and TS IT rack installations.
- Zero-U vertical PDU installations.
