Ask most people involved in data center operations to explain three-phase power to you, and you’ll notice that they get a little squeamish. Except for your Principals of Electricity professor in college, most people have a difficult time explaining three-phase power. Heck, most people have a tough time explaining how power works, period.Read More

We’ve extolled the virtues of single phase 60A power distribution to the rack. But there are still may situations in which a three phase deployment is required to power the needs of racks that consume 12kW or more. In other words, situations that begin with ‘high’ and end with ‘density.’Read More
Considering Power Distribution Units (PDU) for your data center racks and IT equipment should require much more thought than simply selecting a ‘power-strip’ hardware configuration. If you care about Green energy initiatives and desire to save on electricity cost by making the most efficient use of the energy you use, make the move to intelligent rack PDUs if you haven’t already done so. This is particularly true for a new data center build and collocations. If you’re considering a collocation space, choosing the right PDU features will provide additional insight into your true energy use and a tool for capacity planning. We are now seeing large data center growth with collocation providers that charge clients based on actual energy consumed, kilowatt hour (kWh). A well thought out data center power distribution implementation will lead to reduced downtime, improved power monitoring management & control capabilities, and drive greater energy efficiency. The best suited Power Distribution solution requires considerable planning.
Question from Steven G.: How do I calculate the power usage for devices attached to one of your Smart PDU's by looking at the digital readouts on them? I understand the 3-phase power calculation of P=VA*1.73, but is that done on each leg/phase (x,y,z) for the PDU? An example from a CS-24VY-L30MA is X=4.6, Y=4.6, Z=6.3
Topics: 3 Phase power
Lately, we've been getting quite a few questions from customers, channel partners and just about everyone else on 3 phase power. It seems everyone is searching for an effective solution to deliver power to all of the varying devices in their high density cabinets. Rather than trying to re-invent the wheel, we invite you to explore the following resources, all of which we have found to be extremely helpful in discussing 3 phase power with customers.
