The Rittal DK 7979.539 is a high-end three-phase metered Power Distribution Unit (PDU) designed for intelligent power distribution and detailed energy monitoring within IT network and server racks. As part of the Rittal DK PDU metered plus series, it combines 12 IEC 60320 C13 outlets and 12 IEC 60320 C19 outlets with energy measurement for every individual output slot.
Designed for demanding data centre environments, the DK 7979.539 provides detailed visibility into the electrical requirements of individual connected devices. In addition to measurements at phase and infeed level, the PDU measures consumption at each output slot, helping administrators analyse equipment-level energy usage, manage rack capacity and identify abnormal electrical conditions. Adjustable warning and alarm thresholds can be individually configured for current, voltage and power at each output.
Operating from a 400 V AC, 32 A three-phase supply through an EN 60309 / CEE 3L+N+PE, 6h input, the PDU provides a rated power capacity of 22 kW. Its slim 44 × 1695 × 70 mm anodised aluminium housing is designed for vertical Zero-U installation in compatible Rittal VX IT and TS IT racks, providing high-capacity monitored power distribution without consuming valuable 19" rack space.
Metered Plus PDUs such as the Rittal DK 7979.539 provide considerably more detailed energy information than conventional rack power strips or PDUs that measure only at the infeed. Measurement at each individual C13 and C19 output enables administrators to determine the power requirements of specific servers, storage systems and network devices while maintaining visibility of overall three-phase rack loading.
The integrated display, Web server and network interface make consumption information available locally and remotely, while individually configurable warning and alarm limits help identify unusual electrical conditions. Compatibility with SNMP, OPC-UA and Modbus/TCP allows the PDU to integrate with DCIM platforms, while the CAN bus interface can connect up to 16 environmental sensors for wider rack and infrastructure monitoring.
