## Summary description

The Rittal-Werk 7979.440 is a managed three-phase power distribution unit with 42 AC outlets (C13 and C19) and an IEC 60309 input plug. Constructed from aluminium and plastic, it supports 400 V nominal input, up to 16 A and 11,000 W maximum power. Features include LED indicators for power and status, HTTPS/SSL/TLS security, and IP20 protection. Suitable for data centres, server racks and industrial cabinet power distribution where monitored, rack-mounted power management is required.

## Long description

High-end IT rack power distribution unit (PDU) with individual-slot energy measurement and monitoring. This three-phase managed PDU provides a local rotatable display and control unit, redundant internal power packs fed from all phases, and support for C13 and C19 outlets with a total power rating up to 11000 W. The device reports voltage, current, frequency, active and apparent power and energy, power factor and phase angle, and detects load imbalance through neutral conductor current measurement.
Advantages
The PDU includes a rotatable and replaceable controller unit with a bright 128 x 128 pixel TFT, backlight and energy-saving mode, and multi-colour LEDs that indicate per-outlet status and limit conditions. It uses fully-redundant internal power packs supplied from all phases and an error-tolerant supply design so operation is maintained during phase faults. Additional features comprise fuse monitoring for models with integral fuses, position sensors for correct display orientation and accurate web representation, and a low intrinsic power consumption design.
Key specifications
Form factor: rack-mount IT PDU, three-phase managed
Display: rotatable/replaceable controller unit, 128 x 128 pixel TFT (RGB) with back-lighting and energy-saving mode
Measurements: voltage (V), current (A), frequency (Hz), active power, active energy, apparent power, apparent energy, power factor (cosPhi), phase angle
Neutral conductor current measurement for load imbalance detection
Fuse monitoring: supported for PDUs with integral fuse
Indicators: multi-colour LEDs (green/amber/red) per outlet, power LED for voltage indication
Outlets: 42 AC outlets — C13 and C19 couplers
Total power rating: up to 11000 W
Design: integral fully-redundant power pack with supply from all phases; error-tolerant PDU power supply across phases
Power-saving design with minimal intrinsic consumption
How to use
Install the PDU into a standard IT rack following the manufacturer’s mounting instructions. Connect three-phase mains to the designated input terminals so redundant internal power packs receive supply from all phases. Use the rotatable display/controller to view real-time measurements and configure per-outlet limits; display orientation is detected by position sensors and shown correctly in the web interface. Monitor per-outlet status via the multi-colour LEDs and use the management interface for detailed measurements, alerts and remote control.
Recommendations
Ensure three-phase mains are correctly connected and protected for reliable operation. Check fuse options for models with integral fuses, configure per-outlet limits and alerts in the management interface, and regularly review neutral conductor current readings to detect load imbalances and preserve redundancy and low intrinsic power consumption.
