PDU Output Connectors

Compatible plugs from network devices fit into PDU output connectors to establish power distribution. These output connectors, or sockets, are specific to each PDU model. There are power distribution units commonly available which have been fitted with C13 and C19 output receptacles. The International Electrotechnical Commission (IEC) has established standards for electrical connections. C13 and C19 connectors are IEC-classified. IEC sets current capacities for connectors. For example, the C13 connector has a 10-ampere current rating. A C19 connector on a PDU will have a rated current of 16 amps. That’s why C19 connectors are often used in server applications which require higher power, including with PDUs and UPS equipment in the data centre.

A UK Socket PDU

A power socket is a connection point that is also known as a plug-in, outlet or receptacle. A UK socket PDU is designed in accordance with the British Standard, BS 1363. This standard specifies the single-phase, electrical power plugs and sockets found in the UK. The standard UK socket on a PDU accepts a UK plug, with a maximum current rating of 13 amps. When buying a PDU, installers should review the output or input connector specifications of the unit, which can be regionally specific.

IEC C13 and C19 PDU Connections

Both the IEC C13 and C19 PDU designs can be utilized when establishing a system of power management for a network. A PDU with C13 outlets is frequently used in the home or office, while the PDUs with IEC C19 connections are placed in network cabinets for direct device connections. The C19 is needed when output will surpass C13 ratings. Standard and intelligent PDU designs are available with UK sockets, C13 or C19 output, or mixed sockets.
