## Long description

Rittal 7979.240 is a metered three-phase power distribution unit (PDU) for IT racks and network cabinets. It delivers 42 AC outlets (36×C13 and 6×C19) and accepts an IEC 60309 mains connection for nominal 400 V operation at up to 16 A per unit, supporting a maximum combined output of approximately 11,000 W. The unit features an aluminium and plastic IP20 housing, LED indicators for power and status, per-phase energy measurement and network-capable secure communication for remote monitoring and centralized power management.
Advantages
This PDU provides precise per-phase metering with measurement accuracy of ±1% (kWh) to EN 62053-21, enabling reliable energy monitoring and billing or capacity planning. Colour-coded phase and fuse circuits simplify installation and identification. Integrated functions such as a real-time clock with replaceable battery, adjustable alarm thresholds for voltage, current and power, and an operating hours meter increase operational transparency. The unit supports secure communication via HTTPS/SSL/TLS and includes audible alarm capability via an integral electromagnetic buzzer.
Suitable for
 Data centre rack power distribution and metering
 Network cabinets and server racks requiring mixed C13/C19 outlets
 IT environments needing per-phase energy measurement and remote monitoring
 Environments where vertical, zero-U mounting is required
When it may not be suitable
This PDU uses an IP20-rated housing and is intended for indoor use within cabinets or racks; it is not suitable for dusty, wet or outdoor environments that require higher ingress protection. It supports a single IEC 60309 mains input and a 16 A nominal current; locations that require higher input currents, different mains connectors, or single-phase-only distribution may need a different model.
Key specifications
 Input type: IEC 60309 compatible mains connection
 Phases: Three-phase (3~)
 Nominal voltage: 400 V
 Nominal current: 16 A
 Maximum output power: up to ~11,000 W
 Outlets: 36 × C13 and 6 × C19
 Measurement accuracy: ±1% (kWh) to EN 62053-21
 Housing: aluminium/plastic, IP20
 Indicators: LED power and status; TFT display for metering/readout
 Audible alarm: integral electromagnetic buzzer
 Mounting: vertical/zero-U mounting compatible with rack systems
 Communications: HTTPS/SSL/TLS secure network communication
 Additional: integral real-time clock with replaceable battery; adjustable warning/alarm limits
How to use
Install the PDU vertically in the rack’s zero-U space or suitable mounting location, following rack manufacturer guidance for vertical mounting. Connect the IEC 60309 mains supply according to site electrical standards and observe the colour coding for phases and fuse circuits during connection. Use the front panel TFT and LED indicators to read per-phase measurements, set alarm thresholds and configure operating parameters. Integrate the PDU into network monitoring systems via its HTTPS/SSL/TLS interface for remote status, logged consumption and alerting.
What to consider before purchase
 Verify cabinet/rack compatibility for zero-U vertical mounting and available space
 Confirm mains connector type (IEC 60309) and that 16 A / 400 V three-phase supply meets site requirements
 Check that IP20 protection and indoor cabinet installation are suitable for your environment
 Ensure the mix of C13 and C19 outlets (36 C13, 6 C19) matches equipment power connectors
 Plan integration with existing monitoring systems and required secure communication protocols
Usage recommendations
For reliable operation, balance loads across phases where possible and set appropriate warning and alarm thresholds for current and power to avoid overloads. Replace the real-time clock battery according to the maintenance schedule to preserve accurate timestamping of energy data. Use secure network configurations (HTTPS/SSL/TLS) and restrict access to management interfaces to authorised personnel only.
