Power Distribution Unit Rittal 7979.302 6 AC outlets 1U Black

The Rittal 1U power distribution unit provides switched distribution for rack-mounted IT equipment. Designed for vertical installation, it offers six individually switchable C13 outlets and supports single-phase operation up to 16 A (max. 3700 W). The unit includes per-phase measurement, phase colour coding, a TFT display and local status indicators, and an internal real-time clock with battery buffering.

Advantages

This switched PDU delivers precise per-phase measurement with an accuracy of ±1% (kWh) and programmable behaviours for startup and switching. It can be mounted tool-free in compatible racks, includes adjustable alarm limits for voltage, current and output, and features an integral buzzer for acoustic alarms. The device is self-supplied (no external power supply required) and provides resettable operating hour meters for maintenance tracking.

Suitable for

• Rack-mounted servers and network equipment requiring individual outlet control
• IT cabinets with limited U space where vertical (zero-U) mounting is needed
• Environments that need per-phase power measurement and basic alarm functions

When it may not be suitable

This PDU is intended for single-phase installations and therefore is not appropriate for three-phase distribution requirements. It is a 1U unit with six C13 outlets, so it may not fit use cases that require a larger number of outlets, different outlet types, or higher current capacity than 16 A / 3700 W.

Key specifications

• Form factor: 1U, vertical/zero-U mounting compatible
• Outlets: 6 × C13 (switchable individually)
• Input: single-phase, nominal 230 V, max. current 16 A
• Maximum power: 3700 W
• Measurement: per-phase energy measurement, accuracy ±1% (kWh)
• Display and indications: TFT display and LED status indicators
• Controls: programmable startup behaviour and programmable switching (time/logic)
• Alarms and monitoring: adjustable warning/alarm limits for voltage, current and output; integral buzzer
• Clock and logging: real-time clock with battery buffering (replaceable), operating hours meter (resettable)

How to use

Install the PDU vertically in a compatible rack's zero-U space or other supported mounting position according to the rack manufacturer's instructions. Connect the input power and distribute loads to the six C13 outlets, controlling each outlet individually via the front-panel interface. Configure measurement, alarm thresholds, startup behaviour and programmable switching through the TFT display and menu options. Replace the clock battery when indicated to maintain timekeeping and logged operating hours.

What to consider before purchase

• Requires single-phase 230 V supply and is rated for max. 16 A / 3700 W
• Check rack compatibility for vertical zero-U mounting (Rittal VX IT or TS IT racks supported for tool-free attachment)
• Verify that six C13 outlets and individual outlet switching meet your device connection and control needs
• Consider whether per-phase measurement and the provided alarm/monitoring features satisfy your monitoring requirements

Usage recommendations

For reliable monitoring and control, distribute high-draw devices across outlets to avoid exceeding the 16 A limit, set appropriate alarm thresholds for early warning, and schedule periodic checks of the real-time clock battery and operating hour counters.
