DK7979.242 Rittal PDU METERED 16A/3P CEE 42XC13

Why Choose the Rittal DK 7979.242 PDU Metered?

The Rittal DK 7979.242 is an intelligent three-phase metered Power Distribution Unit (PDU) designed for high-end power distribution and energy monitoring within IT racks, server enclosures and network infrastructure. As part of the Rittal DK PDU metered series, it combines 42 IEC 60320 C13 outlets with energy measurement per phase, network connectivity and an integrated display.

Designed for professional data centre environments, the DK 7979.242 measures electrical consumption at the infeed and per phase, providing detailed values including voltage, current, frequency, active power, active energy, apparent power, apparent energy, power factor and phase angle. Measurement accuracy of ±1% for active energy supports dependable capacity planning, while adjustable warning and alarm thresholds help administrators identify abnormal voltage, current and power conditions.

Operating from a 400 V AC, 16 A three-phase supply, the PDU provides a rated power capacity of 11 kW. Its slim 44 × 1695 × 70 mm black anodised aluminium housing supports vertical Zero-U installation in compatible Rittal VX IT and TS IT racks, providing high-density power distribution and intelligent monitoring without consuming valuable 19" rack space.

Three-Phase Energy Monitoring for High-Density IT Racks

Metered PDUs such as the Rittal DK 7979.242 combine high-density rack power distribution with detailed electrical measurement. Monitoring consumption independently across the three phases enables IT administrators to understand rack loading, detect load imbalances, identify abnormal conditions and make informed decisions about available electrical capacity.

The integrated network interfaces enable the PDU to communicate with infrastructure management platforms using protocols including SNMP, Modbus/TCP and OPC-UA. Adjustable thresholds, alarm functionality and compatibility with up to 16 CAN bus environmental sensors further extend its monitoring capabilities, making the DK 7979.242 suitable for sophisticated data centre and distributed IT environments.

Typical Applications

• High-density data centre server racks.
• Server and network equipment power distribution.
• Three-phase rack-level energy monitoring.
• Power load and phase imbalance monitoring.
• Remote IT infrastructure management.
• Network and telecommunications cabinets.
• Rittal VX IT and TS IT rack installations.
• Zero-U vertical PDU installations.
