Do I need a PDU or Extension socket?

There are some that think that Power Distribution Units (PDUs) are just another fancy extension socket. The reality is however that PDUs are often required to be fitted, powered up and left 24/7 for several years in many cases under varying loads and conditions. The build specification between the two types of product should therefore reflect the difference in use.

Furthermore, the nature of the procurement and supply chains often involved means that should a problem occur then it is not only a problem to you but also to your customer and, very often, your customer’s customer.

What is the risk?

When I buy a shirt for £10 and it lasts only three washes it’s a salutary reminder of the truism you get what you pay for. But can you take that risk with a PDU? Many PDUs are protecting personal data, business transactions, indeed people’s livelihoods depend upon them when sitting in data cabinets the length and the breadth of the land. A failure on one of these units has far wider implications than just your extension socket not working on Sunday when you want to vacuum the car.

Here at PDU Online we have been manufacturing for over 45 years in the UK. Discreetly developing our business over the period via the electrical trade and the OEM market. Price is always important in any commercial transaction but on commodities such as PDUs it should take its place alongside quality, reliability, specification, service and delivery.

Whilst global sourcing is a reality in most manufacturing businesses PDU Online, based in the Midlands, have actively mapped out its supply chain to try and buy locally. Buying from trusted local partners and operating a Quality System to ISO9001:2015, we can demonstrate a commitment to quality. Quality of manufacturing system is one thing but quality of before and after sales support is also important. Dealing direct with the manufacturer to provide a solution to meet individual needs, is what we have built our business on

What is the difference?

Most PDUs are made by hard wiring one socket to another and whilst a production line test will reveal whether the assembler has achieved this with no cross polarity connections it will not reveal whether all the connections are adequately tightened or all the strands of the conductors are correctly bundled. This manner of assembly is very labour intensive and therefore has been the reason why so many PDUs have been imported in recent times. As a result, we developed a unique clip-together socket 

system that ensures true connections are made simply by snapping the socket modules together. The bus bars within the design have a cross sectional area of 5.00mm2 compared to the cabled versions of either 1.5mm2 (16A) or 2.5mm2 (25A) which allows units to be simply made to the often required 32 A rating without significant upgrading of the assembly process. 100% testing and full product traceability that accompanies each product is not only meeting compliance to the ISO standard but is simply good practice.

Why PDU Online?

Distance selling does not necessarily mean being distanced from your customer. By having our own CAD design department we are able to enter a dialogue with our customers at the beginning of the process. Drawings can be produced which become a permanent record for any repeat business or be used as part of any technical documents for CE compliance.

Whereas importers can only stock standard ranges and be at the mercy of time and tides. The business model of PDU Online is that no stock of finished product is actually carried but its usual 24 hour turn round is achieved by a flexible manufacturing approach where all materials and sub-assembly variants are immediately available within the factory. Having design and manufacture under one roof enables a quick and efficient process which is essential in an age where ordered today, delivered tomorrow is the expectation.


So why compromise on what you actually want if it is physically possible to achieve it at an affordable price? In previous times a customised item invariably meant expensive as you very often expected to pay more, indeed were prepared to spend more, for the exclusivity of having a rare variant. This applied to cars, a new suit or a pair of glasses. With commodities such as PDUs however customised does not necessarily mean expensive.
