Quick Summary
Rittal 7979239 PDU with energy measurement per phase powers IT racks in data centers. Operators often lack visibility into per-phase loads, risking overloads and wasted energy. This unit complies with EMC Directive 2014/30/EU and EN 62368-1, and carries CE marking for safe, regulatory-compliant operation. Designed for IT networks and server racks, it enables granular energy monitoring, scalable integration, and accurate chargeback reporting. With its robust aluminium housing and a 3 m input lead, installers gain both durability and flexibility in challenging data-center layouts. The optional expansion features, such as ongoing sensor integration and optional overvoltage protection, help future-proof installations. Its web server and SSH access streamline remote management for centralized IT operations.
