Single-phase power

In electrical engineering, single-phase electric power refers to the distribution of alternating current electric power using a system in which
all the voltages of the supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few small
electric motors. Single-phase electricity is what you have in your house. In general, household electrical supply is a single-phase, 220-230 volt AC supply. If you were to take an oscilloscope and measure the powerfrom a normal wall socket in your house, the voltage would be seen as a sine wave, with an effective root mean square (RMS) voltage of 230 volts and an oscillation rate of 50 cycles per second, or 50 Hz. Power that oscillates in this way is generally referred to as alternating current, or AC. The alternative to AC is DC, or direct current, such as that produced by batteries. AC has at least three advantages over DC in an electrical distribution grid:

  • Large electricity generators generate AC
    naturally, so conversion to DC requires an extra
    step.
  • Electrical transformers, which the power distribution
    grid depends on, need an alternating current
    in order to operate.
  • Converting AC to DC is easy, whereas converting
    DC to AC is expensive. This makes AC a better
    choice.

A power distribution unit is a device for controlling electrical power in a data center.

The most basic PDU is a large power strip without surge protection. It is designed to provide standard electrical outlets for data center equipment and has no monitoring or remote access capabilities. The floor-mounted and rack-mounted PDUs can be more sophisticated, providing data that can be used for power usage effectiveness (PUE) calculations.

A floor-mounted PDU, sometimes called a main distribution unit (MDU), provides an important management bridge between a building’s primary power and various equipment racks within a data center or network operations center (NOC). Each PDU can handle larger amounts of energy than an ordinary power strip (300 kilovolt-amps and higher depending on the manufacturer and model) and typically provides power to multiple equipment racks.

A rack-mountable PDU mounts directly to an equipment rack so it can control and monitor power to specific servers, switches and other data center devices and assist in balancing power loads. Rack-mountable PDAs are known by several different names, including smart PDUs and intelligent PDUs. Such PDUs include three-phase displays for devices sharing power well as remote management tools that use the Simple Network Management Protocol (SNMP) to provide administrators with the ability to adjust and monitor power demands from offsite locations Download Datasheet
