Power distribution unit Rittal 7979.416 Managed PDU 28 AC outlets (24×C13, 4×C19) Single-phase 230V 32A 3m cable Black

Rittal 7979.416 is a managed 0U rack power distribution unit (PDU) designed for single-phase 230 V IT environments. The unit provides 28 AC outlets (24×C13 and 4×C19), supports up to 32 A and a maximum load of 7,400 W, and is supplied with a 3 m power cable in a black finish. Integrated metering and monitoring deliver per-outlet current and voltage measurement, and the PDU supports multiple network protocols for remote management and firmware updates.

Advantages

The managed design offers precise energy measurement (kWh accuracy ±1% to EN 62 053-21) and per-outlet monitoring, allowing individual outlet limits, alarms and programmable switching. Network protocol support (HTTP/HTTPS, SNMP, Modbus/TCP, OPC-UA, SSH, Telnet, TCP/IP v4 & v6, DHCP, DNS, NTP) and USB firmware update capability enable flexible integration into existing data centre management systems. Tool-free mounting options for compatible racks and colour-coded phase/fuse indication simplify installation and maintenance.

Suitable for

• Data centre and server rack power distribution where per-outlet monitoring and control are required
• IT closets and network cabinets using 230 V single-phase supply with up to 32 A input
• Environments requiring integration with SNMP, Modbus/TCP or OPC-UA management systems
• Racks where a 0U vertical PDU is preferred to preserve U space

When it may not be suitable

This PDU is single-phase 230 V only, so it is not suitable for three-phase power systems that require balanced multi-phase distribution. It is intended for environments that can accept a single input up to 32 A and a CEE-style input connector; installations requiring different input types or integrated mains distribution should consider alternative products.

Key specifications

• Input voltage: 230 V nominal (single-phase)
• Maximum current: 32 A
• Maximum power: 7,400 W
• AC outlets: 28 total (24×IEC C13, 4×IEC C19)
• Mounting: 0U vertical mounting for rack installation
• Monitoring: Per-outlet current and voltage measurement; energy measurement accuracy ±1% (kWh)
• Communication: HTTP/HTTPS, SNMP, Modbus/TCP, OPC-UA, SSH, Telnet, DHCP, DNS, NTP, TCP/IP v4 & v6
• User interface: TFT display and programmable settings (startup, switching behaviour)
• Cable: Supplied with 3 m power cable
• Colour: Black
• Weight: 5.74 kg

How to use

Mount the PDU vertically in the rack zero-U space according to the rack manufacturer's instructions and connect the CEE input to the appropriate supply. Use the onboard TFT and network interface to configure network settings and monitoring parameters, set per-outlet limit values and program startup or switching behaviour. Monitor current, voltage and energy consumption remotely via supported protocols or locally through the display. Perform firmware updates via the USB interface when required.

What to consider before purchase

• Confirm that your rack and power infrastructure support a single-phase 230 V input with a CEE-style connector and up to 32 A.
• Verify that 28 outlets (24 C13 + 4 C19) match the types and number of devices to be powered.
• Ensure compatibility with your network management systems (SNMP, Modbus/TCP, OPC-UA, etc.).
• Check available vertical space (0U mounting) and any required tool-free mounting accessories for your rack model.

Usage recommendations

Balance connected loads across outlets where possible, configure per-outlet limits to prevent overloads, and enable SNMP or Modbus/TCP monitoring for continuous visibility. Schedule firmware updates during maintenance windows and replace the backup battery for the real-time clock when indicated by the device diagnostics.
