Zero-U space integration enables 800 mm wide IT racks to host modular power distribution without sacrificing cabinet depth or airflow, increasing rack density and reducing wiring complexity in critical data centers. The DK 7859.090 delivers 1~, 32 A rated capacity with a fixed/CEE connection and 5 module slots, providing scalable distribution tailored to evolving workloads while minimizing hardware footprints and installation time. A 3 m connection cable simplifies installation across enclosure faces, lowering in-rack cabling and related heat generation. Aluminium section with natural anodised finish offers a corrosion-resistant, durable build suitable for demanding environments, improving long-term reliability and reducing maintenance intervals. IP20 protection supports indoor IT environments, while the product’s compatibility with VX IT enclosures up to 2000 mm height ensures a consistent, plug-and-play upgrade path. The modular PDU also benefits from precise ETIM and ECLASS classifications, streamlining technical data transfer and procurement workflows. In short, this solution reduces capital and operating costs by delivering scalable, space-efficient power distribution with straightforward servicing and compliance alignment.

FAQs
The DK 7859.090 is designed for vertical installation in the zero-U space between the side panel and the 482.6 mm (19-inch) mounting level in 800 mm wide IT racks. It uses a fixed/CEE connection, 1 infeed, and a 3 m lead, with up to five module slots. Ensure the enclosure height is at least 2000 mm and that the internal environment meets 5 °C to 45 °C and 10–90% non-condensing humidity requirements. This setup minimizes cable clutter and simplifies future upgrades because the module slots can be populated as needs evolve.
The PDU is a single-phase 1~, rated up to 32 A, with one infeed, five module slots, and a 1,695 mm length. It uses a fixed/CEE electrical connection and includes a 3 m connection cable. The design supports modular power distribution in 800 mm wide IT racks and is intended for environments that require reliable, scalable distribution with straightforward wiring.
Yes. The PDU is specifically engineered for zero-U installation, occupying space between the side panel and the 19-inch mounting level in 800 mm wide racks. Its 1,695 mm length and five module slots provide scalable distribution without sacrificing cabinet depth, while the 3 m lead and CEE connector simplify installation in tight spaces and reduce the need for additional cabling runs.
The unit uses aluminium with natural anodising for durability and carries an IP20 protection rating suitable for indoor IT environments. It aligns with ETIM 9 EC002762 and ECLASS 8.0 27371306, aiding data-driven procurement and data sheet consistency. While CE marking is a common expectation for electrical equipment, this product’s documented standards focus on protection, material, and classification to streamline compliance in regional markets.
The modular PDU reduces rack footprint by leveraging zero-U space, enabling higher rack density and easier cable management. Its 32 A capacity supports standard IT loads while five module slots allow scalable distribution. Durable aluminium construction lowers maintenance and replacement costs, and its compatibility with VX IT enclosures simplifies lifecycle planning and future expansions, delivering a lower total cost of ownership.
