In the quest for more power efficient data centers, is there any trend in the US to move to 240V/415V three phase power distribution in the data center racks? (or 230V/400V) I would not expect the ...

An innovative approach, the VPC2864 series 3-phase vertical power distribution unit includes current metering on each phase to properly balance and load the system via a 2-digit current meter display.

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

While applications for 1-Phase PFC are now familiar and prevalent, the same is not the case with 3-Phase PFC. Many equipments using kilowatts of power from 3-Phase mains should be candidates of ...
