Power Distribution Unit Rittal 7979.140 42 AC outlets 0U Black

The Rittal 7979.140 is a compact 0U power distribution unit designed for professional IT rack environments. It provides 42 AC outlets (C13 and C19) and comes with a 3 m power cable. With a maximum current rating of 16 A and a maximum power of 11000 W, it supports three-phase supply and is intended for basic, reliable power distribution in data center or server rack installations. Its slim housing (1495 mm × 44 mm × 70 mm) allows efficient use of rack space, including mounting in zero-U or horizontal 19" positions depending on model configuration.

Advantages

The unit offers a high-density outlet configuration in a compact 0U form factor, enabling installation without occupying valuable rack units. Its combination of C13 and C19 sockets covers a wide range of IT equipment, while a 3 m cable provides flexible connection to upstream power sources. Rated for 16 A and up to 11000 W, the PDU supports three-phase setups and basic professional power distribution needs in server rooms and network cabinets.

Suitable for

• Server racks and network cabinets requiring compact, high-density power distribution
• Three-phase power environments with devices using C13 and C19 connectors
• Installations where 0U or horizontal 19" mounting is preferred to save rack space

When it may not be suitable

This PDU is a basic power distribution unit without advanced monitoring, remote management, or individual outlet switching. It may not be suitable when detailed power metering, remote control, environmental sensors, or outlet-level management are required. Also, its 16 A maximum current rating should be verified against the total load of connected equipment to avoid overload.

Key specifications

• Form factor: 0U (zero-U) compatible, horizontal 19" or vertical mounting options
• AC outlet count and types: 42 outlets (combination of C13 and C19)
• Maximum current: 16 A
• Maximum power: 11000 W
• Cable length: 3 m
• Colour: Black
• Dimensions (approx.): 1495 mm × 44 mm × 70 mm

How to use

Mount the PDU in the rack according to available space and the chosen orientation (horizontal 19" level or vertical/zero-U). Secure cabling and route the 3 m supply cable to the appropriate upstream power source or distribution panel. Connect IT equipment using compatible C13 and C19 power cords, ensuring the combined current draw of connected devices does not exceed 16 A. Follow local electrical codes and the rack infrastructure guidelines during installation.

What to consider before purchase

• Verify total expected load of connected equipment to ensure it does not exceed 16 A or 11000 W
• Confirm required outlet types and quantities (C13 vs C19) match your devices
• Decide on mounting orientation (zero-U vertical or horizontal 19") based on rack layout
• Assess whether advanced features (monitoring, remote control) are needed — this is a basic PDU

Usage recommendations

For reliable operation, balance loads across phases in three-phase environments, secure power cords to prevent strain on outlets, and periodically check connections. If monitoring or outlet-level control is required, consider a managed PDU option instead.
