Product description
PDU metered 16A/3P CEE 36xC13+6xC19, DK PDU metered, Compact basic power distributor incl. energy mearsuremnt per phase, with network interface and display, WHD: 44x1895x70 mm
Metered energy per phase is embedded in the DK 7979.240, allowing exact monitoring of power draw at the infeed or per phase. This translates to actionable data for capacity planning, chargeback, and cooling optimization, reducing waste and improving service levels in data centers. In practice, facilities teams gain visibility without additional meters or complex wiring. The 36x C13 and 6x C19 outlets support full IT rack power distribution needs, enabling servers, storage, and networking gear to be powered from a single, centralized PDU while preserving cable management and clearance. The business impact is straightforward: fewer outages caused by overloaded outlets and more predictable maintenance windows, supported by long-term operating cost reductions. The rotatable display/controller unit simplifies local configuration and diagnostics, especially in dense rack environments where access can be constrained. USB 2.0 for mass configuration and firmware updates accelerates deployment, reduces on-site service visits, and enables data logging for audits. The zero-U mounting capability for VX IT enclosures saves valuable rack space, improving density and reducing total cost of ownership. Optional overvoltage protection and sensor integration provide proactive risk management, while the standard operating range of 5 °C to 50 °C and 10–95% relative humidity ensures reliability in data-center and edge scenarios. Together, these features translate to enhanced operational efficiency, compliant infrastructure, and a smoother path to scalability in modern IT environments.
