Power Distribution Unit Rittal 7979.139 24 AC outlets 0U Black Silver

The Rittal 7979.139 Power Distribution Unit (PDU) is a 0U rack-mounted power strip offering 24 AC outlets in a mix of C13 and C19 socket types. Designed for data center and network cabinets, this PDU accepts a nominal input voltage of 230 V, supports up to 32 A of current and a combined power capacity of 22,000 W. Its compact 0U form factor and two-tone silver and black finish allow installation without occupying usable rack units while providing broad compatibility with servers, switches and other rack equipment.

Advantages

The unit provides centralized power distribution for multiple devices in a single rack, reducing the need for separate power strips and improving cable management. With 24 AC outlets (C13 and C19) it accommodates both standard IT equipment and higher-current devices. The 32 A maximum current rating and 22,000 W capacity support consolidated power delivery for dense rack configurations. The 0U mounting preserves rack space and the metal housing in silver and black offers robust construction suitable for professional environments.

Suitable for

• Data center racks and server cabinets requiring multiple AC outlets
• Network closets and equipment rooms with mixed C13 and C19 device connections
• High-density rack installations where 0U mounting is preferred
• Environments needing up to 32 A input and up to 22,000 W total power delivery

When it may not be suitable

This PDU is a basic non-switched distribution unit; it does not include remote monitoring, individual outlet switching, metering or surge protection integrated on the unit. If remote power control, outlet-level metering, environmental sensors or advanced power management features are required, a managed or metered PDU would be more appropriate. Also, ensure that rack power infrastructure and upstream cabling can safely supply a 32 A input.

Key specifications

• Form factor: 0U rack-mounted
• Outlet types and count: 24 AC outlets (combination of C13 and C19)
• Nominal input voltage: 230 V
• Maximum current: 32 A
• Maximum power capacity: 22,000 W
• Product colour: Silver and Black
• PDU type: Basic (non-switched)

How to use

Mount the PDU in the rack using the 0U mounting position to avoid occupying vertical rack units, following the rack manufacturer’s instructions. Connect the PDU to a compatible 230 V, 32 A power supply or distribution source using appropriate cabling and connectors rated for the current. Plug C13 and C19 equipped devices into the matching outlets, balancing load across outlets where possible. Verify upstream protection (breakers/fuses) and confirm total rack load does not exceed the 32 A rating or the 22,000 W capacity.

What to consider before purchase

• Confirm upstream power source and cabling support 230 V at up to 32 A.
• Check whether C13 and C19 outlet mix matches your devices’ plugs.
• Decide if features like remote monitoring, outlet switching, metering or surge protection are required; this model is a basic PDU without those features.
• Ensure proper rack mounting space and clearance for a 0U installation.

Usage recommendations

Distribute connected equipment load evenly across outlets, document circuit loads during installation, and ensure the upstream breaker rating and cabling match the PDU’s 32 A specification. For critical systems, pair this basic PDU with external surge protection and consider combining it with environmental monitoring or redundant upstream feeds where necessary.
