The Rittal DK 7979.131 is a robust three-phase basic Power Distribution Unit (PDU) designed for professional power distribution within IT racks, server enclosures and network infrastructure. As part of the Rittal DK PDU basic series, it combines a high-capacity three-phase input with 12 IEC 60320 C19 outlets for powering servers, storage systems and other demanding rack-mounted equipment.
Designed for high-density IT environments, the DK 7979.131 operates from a 400 V AC, 32 A three-phase supply and provides a rated power capacity of 22 kW. Six integrated 16 A hydraulic-magnetic circuit-breakers provide circuit protection, while colour coding identifies the individual phases and fuse circuits as L1 pink, L2 black and L3 white for straightforward load management.
With dimensions of 44 × 1095 × 70 mm, the PDU provides substantial power distribution capacity in a slim anodised aluminium housing. Vertical mounting in the Zero-U space of compatible Rittal VX IT and TS IT racks helps preserve valuable 19" equipment space, making the DK 7979.131 particularly suitable for professional data centres and high-density server installations.
The Rittal DK 7979.131 provides a straightforward solution for distributing substantial three-phase electrical loads within professional server and network racks. Its 12 C19 outlets are suited to equipment with higher power requirements, while the integrated hydraulic-magnetic circuit-breakers provide dedicated protection for the output circuits.
The slim aluminium housing is particularly advantageous in high-density data centres where conventional rack space must be reserved for active equipment. Tool-free vertical installation in the Zero-U area of compatible Rittal VX IT and TS IT racks allows the PDU to provide up to 22 kW of rack-level power distribution without consuming valuable 19" rack units.
