Power distribution unit Rittal 7979.433 Managed PDU 18x Type F outlets 400 V 16 A 11 kW 3 m cable Grey

The Rittal 7979.433 Managed PDU is a three-phase power distribution unit designed for IT racks, network cabinets and industrial enclosures that require monitored and controllable AC power. It provides 18 Type F (Schuko) outlets for distributing 400 V power with a rated input current of up to 16 A and a maximum aggregated power of 11 kW. Housed in an aluminium and plastic enclosure with a grey finish and supplied with a 3 m power cable, this managed PDU integrates energy measurement and monitoring for each individual outlet and supports programmable switching and startup behaviour.

Advantages

This managed PDU delivers per-outlet energy measurement with ±1% kWh accuracy to EN 62053-21 and offers configurable alarms and limit values for current, voltage and power on each outlet. It supports programmable switching logic and startup behaviour after power recovery, includes an internal real-time clock with battery buffering, and provides visual phase/fuse colour coding for simpler installation and operation. The device is designed for tool-free mounting in compatible racks and does not require an external power supply for its management functions.

Suitable for

• Server racks and data centre cabinets needing per-outlet monitoring and control
• Network equipment cabinets where three-phase 400 V distribution with Schuko outlets is required
• Industrial enclosures that require documented energy measurement and alarm thresholds
• Installations that benefit from programmable startup and scheduled switching of loads

When it may not be suitable

This PDU is intended for three-phase 400 V systems and is rated for up to 16 A input and 11 kW total; it is not suitable for single-phase 230 V applications that require a different outlet configuration. It also requires racks or enclosures that accept vertical or zero-U mounting; installations without appropriate mounting space or with incompatible mounting standards will need an alternative mounting solution.

Key specifications

• Number and type of outlets: 18 x Type F (Schuko)
• Rated voltage: 400 V (three-phase)
• Rated input current: 16 A
• Maximum power capacity: 11,000 W
• Cable length: 3 m supply cable
• Enclosure material: aluminium and plastic, grey finish
• Per-outlet energy measurement with ±1% kWh accuracy (EN 62053-21)
• Programmable switching and startup behaviour; adjustable limit values per outlet
• Integrated real-time clock with replaceable battery and acoustic buzzer for alarms
• Colour-coded phases and fuse circuits for L1/L2/L3

How to use

Install the PDU vertically in the rack’s zero-U space or other compatible mounting position following the rack manufacturer’s instructions. Connect the 3 m supply cable to the appropriate three-phase source using the correct inlet/connector for the installation. Configure network access and management settings according to the supplied documentation, then set per-outlet measurement thresholds, programmable startup behaviour and scheduled switching as required. Use the monitoring interface to view current, voltage and energy data and to receive alarms when configured limits are exceeded.

What to consider before purchase

• Ensure your installation uses three-phase 400 V supply and that 16 A input and 11 kW total capacity meet your load requirements
• Verify that your rack or cabinet supports vertical or zero-U mounting and that space is available for a 3 m cable
• Confirm compatibility of Type F (Schuko) outlets with the plug types used by your equipment
• Plan network access and authentication requirements for managed PDU functions

Usage recommendations

For accurate monitoring and reliable operation, balance loads across phases, set appropriate warning and alarm thresholds per outlet, and schedule non-critical equipment to power up after confirming the programmed startup behaviour. Replace the real-time clock battery according to maintenance intervals stated in the documentation to retain scheduled functions.
