Power distribution unit Rittal 7979.114 — Basic three-phase PDU, 16 AC outlets, 230 V, 32 A, 3 m cable, Silver

The Rittal 7979.114 is a basic three-phase power distribution unit (PDU) designed for 0U rack mounting to deliver concentrated AC outlet capacity in server racks, network cabinets and industrial enclosures. It accepts a 230 V nominal input and supports up to 32 A input current, providing up to 7,400 W of total power through 16 AC outlets. Supplied with a 3 m power cable and finished in silver, this PDU is intended for straightforward power distribution where a compact, rack-friendly, multi-outlet solution is required.

Advantages

The unit offers a compact 0U form factor that saves rack space while providing a high number of outlets for multiple devices. Its ability to accept 230 V at up to 32 A enables distribution of substantial power in a single, centrally mounted device. The 3 m cable length allows flexible placement within standard cabinet installations, and the silver housing provides a neutral appearance that integrates with most rack and enclosure designs.

Suitable for

• Server racks and data centre cabinets requiring multiple AC outlets in a 0U position
• Network cabinets and telecom enclosures with concentrated device power needs
• Industrial control cabinets where reliable multi-outlet AC distribution is needed
• Laboratory racks or test benches that use several 230 V devices simultaneously

When it may not be suitable

This basic PDU does not include advanced monitoring, metering or outlet-level switching features; it is intended for simple power distribution rather than intelligent power management. It also does not provide surge protection or built-in redundancy—additional components would be required if surge suppression or power redundancy is needed.

Key specifications

• Nominal input voltage: 230 V
• Maximum current: 32 A (maximum combined output power up to approximately 7,400 W)
• AC outlets: 16 outlets
• Form factor: 0U rack-mounted PDU
• Power cable length: 3 m
• Colour: Silver

How to use

Mount the PDU in a 0U position inside the rack or cabinet following the enclosure manufacturer’s mounting guidance. Connect the supplied 3 m cable to a compatible 230 V supply capable of delivering up to 32 A. Distribute connected equipment across the 16 AC outlets, taking care to calculate total connected load so as not to exceed the 32 A maximum. Regularly inspect connections and the cable for wear; power down connected equipment before performing maintenance.

What to consider before purchase

• Confirm available supply: ensure the rack or facility provides a 230 V feed with sufficient capacity (32 A) for the intended load
• Load calculation: add the power ratings of all devices to ensure the combined load does not exceed the PDU capacity
• Required features: determine if you need metering, outlet switching, surge protection or redundancy that this basic model does not provide
• Compatibility: check outlet types match the plugs of your equipment and that the PDU’s form factor fits your rack layout

Usage recommendations

Distribute high-draw devices across outlets to avoid concentrating load on adjacent outlets, perform a formal load calculation prior to installation, and consider installing surge protection or an upstream breaker if the environment requires enhanced electrical protection. For environments that require monitoring or remote control, consider an intelligent PDU instead of the basic model.
