PDU Rittal 7979.210 metered power distribution unit 13 AC outlets (12×C13 + 1×C19) 230V 16A, 3 m cable, black

The Rittal 7979.210 metered power distribution unit (PDU) delivers monitored, rack-mounted power distribution for data centres and server rooms. Designed for vertical (0U) installation in IT racks, this black PDU accepts a 230 V nominal input at up to 16 A and supplies 13 AC outlets (12×C13 and 1×C19), with a total output capacity up to 3700 W. It features integrated current and voltage measurement, a 3 m power cable and an aluminium/plastic housing. Network management is supported via HTTP/HTTPS, SNMP, Modbus/TCP and OPC‑UA, and firmware updates can be performed via USB.

Advantages

The unit provides accurate energy measurement with ±1% kWh accuracy to EN 62 053-21 and includes an integral real-time clock with battery buffering for stable timestamping of measurements and events. Colour-coded phase marking and adjustable alarm thresholds for voltage, current and output simplify monitoring and fault detection. The PDU is self-supplied so no external supply is required, and an integrated acoustic buzzer and operating hours meter support operational management.

Suitable for

• Rack-mounted servers, switches and network appliances requiring consolidated AC distribution and monitoring
• Data centre rows or cabinet-level power management where 0U vertical mounting is needed
• Environments needing networked monitoring via SNMP, HTTP/HTTPS, Modbus/TCP or OPC‑UA
• Installations requiring a mix of C13 and C19 outlets for IT equipment

When it may not be suitable

This PDU is intended for single-phase 230 V systems up to 16 A and is not suitable for three-phase high-current distribution or locations requiring higher than 3700 W output. It is a metered device focused on monitoring rather than remote outlet-level switching; if per-outlet switching or switched PDU functionality is required, choose a switched model instead.

How to use

Install the PDU vertically in the rack’s zero-U space or suitable vertical mounting position following rack manufacturer guidelines. Connect the PDU to a 230 V, 16 A supply using the integrated 3 m power cable. Plug IT equipment into the C13 and C19 outlets according to the equipment’s inlet type. Access the PDU’s web interface or management protocols (SNMP, Modbus/TCP, OPC‑UA) to view live voltage and current readings, configure alarm thresholds and record energy consumption. Use USB for firmware updates and replace the real-time clock battery when service intervals indicate.

What to consider before purchase

• Verify the rack supports vertical 0U mounting and has space for the PDU
• Confirm your IT equipment requires the provided mix of C13 and C19 outlets
• Ensure your supply is a single-phase 230 V circuit rated up to 16 A
• Decide if metered (monitoring-only) functionality meets your needs or if a switched PDU is required
• Plan network access and protocol compatibility for SNMP, HTTP/HTTPS, Modbus/TCP or OPC‑UA integration

Usage recommendations

Distribute connected equipment across outlets to balance load and set appropriate alarm thresholds to detect overcurrent or undervoltage conditions early. Regularly monitor logged measurements and perform firmware and battery maintenance to ensure accurate metering and reliable operation.
