Power Distribution Unit Rittal 7979.131

The Rittal 7979.131 is a 0U power distribution unit designed for efficient, compact power management in equipment racks. It provides twelve C19 AC outlets, a three-metre input cable and supports up to 32 A at 230 V, enabling a maximum power delivery of approximately 22,000 W. With a narrow profile (1095 mm × 44 mm × 70 mm) and black finish, this basic three-phase PDU is intended for reliable distribution of electrical power to servers, network devices and other rack-mounted equipment in space-constrained installations.

Advantages

The unit combines a high outlet count with a slim 0U form factor, allowing installation without consuming rack mounting units. Twelve C19 sockets support higher-current peripherals and provide compatibility with common rack power cords. A 3 m input cable simplifies connection to rack power sources while the 32 A rating and 230 V nominal voltage allow three-phase configurations and substantial aggregate power delivery. The black enclosure and compact depth help integrate the PDU into dense rack environments without protruding into equipment space.

Suitable for

• Data center and server rack power distribution where vertical space is limited
• Network and telecommunications racks with multiple C19-powered devices
• Small to medium enterprise server rooms requiring up to 32 A input capacity
• Environments that need a basic, reliable three-phase PDU without advanced monitoring

When it may not be suitable

This basic PDU does not include remote monitoring, metering or outlet-level control, so it may not meet needs where power consumption monitoring, remote rebooting or detailed load balancing are required. It is also not a surge-protected or UPS-backed device; installations that require surge suppression or battery backup should consider additional equipment.

Key specifications

• Form factor: 0U rack-mountable
• Input voltage (nominal): 230 V
• Maximum current: 32 A
• Number and type of outlets: 12 × C19 AC outlets
• Power capacity: up to approximately 22,000 W (at 230 V, 32 A aggregate)
• Cable length: 3 m input cable
• Dimensions (W × D × H): 1095 mm × 44 mm × 70 mm
• Colour: Black

How to use

Mount the PDU in a suitable 0U position within the rack so it does not occupy U-space required for equipment. Route the 3 m input cable to the appropriate rack power source or distribution block and ensure the supply matches the unit rating (230 V nominal, up to 32 A). Plug rack equipment into the C19 outlets using compatible power cords and distribute load to avoid exceeding the overall current rating. Periodically inspect connections and cable routing to maintain airflow and prevent obstructing equipment cooling paths.

What to consider before purchase

• Verify that rack power infrastructure supports a 32 A input and the required three-phase configuration if applicable
• Confirm connected devices use C19 inlet plugs and that the number of outlets meets current and future needs
• Decide if monitoring, outlet switching or surge protection is required—this basic model does not include those features
• Check rack depth and mounting options to ensure physical compatibility with the PDU dimensions

Usage recommendations

Distribute high-draw devices across multiple outlets to balance load and avoid localized overheating. Combine this basic Rittal 7979.131 PDU with external surge protection or UPS systems where electrical protection or runtime is required. Follow local electrical codes and, when in doubt, consult a qualified electrician for installation and load planning.
