Quick Summary
The Rittal DK 7979.332 PDU provides switched power distribution with per-phase energy measurement for IT racks in data centers. Engineers often struggle to see and control power at the slot level in dense racks, risking inefficiency, overheating, and unplanned downtime. CE compliance and EN 62368-1 certification support regulator audits, while the modular web server and SSL/TLS protection help maintain data integrity. Its zero-U mounting for VX IT racks eliminates tool requirements and frees rack space, while the rotatable display improves local configuration and fault diagnosis. This configuration supports data center power distribution and energy management with remote monitoring, enabling faster incident response and sustained energy efficiency.
