Power distribution unit Rittal DK 7979.814 — Basic PDU, 20 AC outlets (16x BS 1363, C19), 230V 16A, 3 m cable

The Rittal DK 7979.814 Basic PDU is a rack-mount power distribution unit designed for IT, telecom and data centre environments that require straightforward, reliable AC power delivery. This unit provides 20 AC outlets, including sixteen BS 1363 sockets and a single IEC C19 coupler, accepts 230 V nominal input at up to 16 A and delivers up to 3,700 W via an integrated 3 m supply cable. The design follows recognised safety and electromagnetic compatibility standards, making it suitable for standard server racks and equipment cabinets where a simple, durable PDU is required.

Advantages

The PDU offers a compact and robust solution for distributing AC power across multiple devices in a rack. With a mix of BS 1363 sockets and a C19 coupler it supports common server and network equipment configurations without additional adapters. The fixed 3 m cable simplifies installation in typical rack layouts while the 16 A, 230 V rating allows continuous operation of multiple devices up to the combined power limit.

Suitable for

• Standard 19-inch server and network racks requiring multiple BS 1363 outlets
• Small and medium data centres or telecom cabinets with mixed equipment
• IT rooms where a basic, non-switched PDU is sufficient for power distribution
• Environments needing a C19 outlet for high-current appliances alongside BS 1363 sockets

When it may not be suitable

This basic PDU does not include remote monitoring, switching, or per-outlet metering, so it is not suitable where active power management, outlet control or detailed consumption reporting is required. Environments needing redundant power feeds, automatic transfer switching or intelligent rack power management should consider managed or redundant PDUs instead.

Key specifications

• Number of AC outlets: 20 (16 BS 1363 sockets, 1 IEC C19 coupler plus remaining outlets as specified)
• Nominal input voltage: 230 V AC
• Maximum current: 16 A
• Maximum power: 3,700 W
• Supply cable length: 3 m
• Form factor: Rack-mount PDU suitable for standard server cabinets
• Standards: Conforms to applicable safety and EMC standards for IT equipment

How to use

Mount the PDU securely within a compatible 19-inch rack or cabinet in a location that provides good access to the outlets. Route the 3 m supply cable to a suitable mains outlet rated for 230 V and 16 A, ensuring the supply can handle the combined load of connected devices. Distribute equipment across the available sockets to avoid exceeding the total current and power ratings; calculate the summed device power to stay within the 3,700 W limit. Follow local electrical codes and safety procedures when connecting high-current devices to the C19 coupler.

What to consider before purchase

• Confirm rack compatibility and available mounting space for a basic rack-mount PDU
• Verify that 230 V / 16 A supply and circuit capacity are available where the PDU will be installed
• Check the outlet types match the plugs of your equipment (BS 1363 and IEC C19)
• Decide whether you need managed features (monitoring, remote switching) that this basic unit does not provide

Usage recommendations

Balance high-draw devices across the outlets and avoid grouping all power-hungry equipment on adjacent sockets. Regularly inspect connections and ensure ventilation within the rack to maintain safe operating temperatures for both the PDU and connected equipment.
