Quick Summary
Rittal DK 7979.433 PDU delivers high-end power distribution for IT racks, with integrated energy measurement and per-output monitoring. Engineers often struggle to see which outlets consume the most power, risking inefficiency and downtime. The solution complies with EMC Directive 2014/30/EU and EN 62368-1 with CE marking, offering robust safety and regulatory assurance. The built-in web server, PoE-enabled Ethernet interface, and rotatable display enable remote management, real-time energy visibility, and reliable IT operations across data centers and server rooms. In practice, per-slot data supports chargeback, capacity planning, and fault isolation, making maintenance teams more productive and procurement more informed about energy-efficient hardware.
