The PDU – or power distribution unit – has been the backbone of data center power distribution architecture for many decades. Today’s models are evolving faster than ever, reflecting the needs and demands of the industry. In the last ten years alone, the progress of this technology has seen tremendous growth – all of which is changing the way data centers function positively.

How PDU Technology is Adapting

As consumer needs have changed, PDU manufacturers have had to adapt their products, as well. One of the ways they are doing this is by compartmentalizing the lower- and higher-powered areas of the PDU. What benefit does this have? Varying flash energy calculations can be applied to the different areas of the PDU, meaning that maintenance professionals won’t have to suit up quite so drastically when working in the lower-power areas of the unit. This saves time and trouble and keeps things moving more smoothly.

The compartmentalization is also great for safety. It allows for the addition of high-tech, newly reimagined distribution breakers to make adding circuits safer than ever before. The improvement of both the electrical and mechanical technology used in these breakers means they are both more efficient and safer.

More Breakthroughs in Power Distribution

What else are today’s data centers doing to improve their energy distribution and usage? In some cases, facilities have actually eliminated PDU technology altogether. However, this is not advisable for most centers. Instead, these techniques are becoming popular in more conservative approaches to shaking up power distribution:

  • Distribution of medium voltage to the IT racks where it can then be stepped down as needed.
  • Expansion of sub-feeds.
  • Designs including transformer impedance, reducing fault current in whitespace.
  • Busway integration optimization, as well as AC and DC rectification in direction to equipment racks.
  • Implementation of reactor-based PDU technology.
  • Enhanced safety for compartmentalization for wiring down feeders, creating a scenario in which technology can grow with a center.

What to Look for in Your PDU Supplier

If your center is ready to implement improved PDU technology, you’ll need to know what to look for in a provider. Some tips include:

  • In-house magnetic engineering capability.
  • In-house transformer manufacturing.
  • Offerings that include Static Transfer Switches and a record of reliability when it comes to their technology.
