What are three phase PDUs and when might they be used?

Three-phase PDUs distribute electricity from a three-phase power supply, which means they are often the sensible choice for larger server rooms and data centres with high power demands. Unlike single-phase PDUs, they can spread electrical loads across three phases, helping to manage power distribution more efficiently and reduce the risk of overloading individual circuits. They require a compatible three-phase electrical supply and, where backup power is needed, a suitable UPS.
