FAQs
Yes. The DK PDU metered+ is designed for vertical mounting in VX IT enclosure frames and can be installed in zero-U spaces. It supports VX IT frames and TS IT frames with appropriate mounting angles and is supplied as a complete assembly, including the necessary assembly parts for a quick, tool-free installation. This makes it ideal for high-density IT racks where space is at a premium.
The PDU provides energy measurement per output slot, with measurement options per phase or infeed. Data is accessible via the USB 2.0 interface for mass configuration and firmware updates, and through the built-in web server (HTTP/HTTPS) for remote monitoring. This enables granular visibility into outlet-level consumption and supports efficient capacity planning.
The DK 7979.537 operates at 400 V AC with a rated current of 32 A and accommodates 24 C13 sockets plus 6 C19 sockets, totaling a 22 kW maximum load. Infeed is 1 with three phases, and a 3 m connection cable uses a CEE connector. Optional protections include Type 3 overvoltage with interchangeable arresters and residual current measurement (Type B).
This PDU meets CE marking requirements and EN 62368-1 safety standards, with compliance to the EMC Directive 2014/30/EU. These certifications ensure regulatory readiness for IT environments and help assure safety, reliability, and interoperability in professional data centers and industrial IT applications.
Zero-U mounting in VX IT frames reduces installation time and frees up valuable rack space, while the rotatable display and USB/web interfaces simplify commissioning and ongoing maintenance. Regular firmware updates, remote monitoring, and energy transparency contribute to faster troubleshooting, lower energy waste, and a measurable return on investment through improved capacity planning and operational efficiency.
