I would like to know what is the main differences between a power strip, a power distribution unit (PDU) and a remote power switch.

Thank you.

  • did you research what any of these are before asking... – Daniel Widrick Sep 16 '13 at 15:05
  • Yes, but they seem quite the same. I wanted a precise definition for each of them because they seem to be often confused on hardware websites! Should I delete the post? – MarAja Sep 16 '13 at 15:31

Power Distribution Unit: http://en.wikipedia.org/wiki/Power_distribution_unit

Power Strip: http://en.wikipedia.org/wiki/Power_strip

A power strip adds outlets. A Power distribution unit distributes higher voltage and current into lower current and voltage (EG a 30amp 220v feed into two 15amp 110v feeds). A remote power switch allows power cycling generally via a network connection.

Much like modern modems, routers, switches a single unit may contain features of all three.

  • I think your final sentence is the best part of the answer. – TheCleaner Sep 16 '13 at 15:46

    The term "PDU" is often also used for Rack mounted power strips ([some companies prefer the term **CDU**, as do I](http://www.servertech.com/support/technical_library/cdu_vs_pdu/)). "Rack PDUs" (CDUs) usually don't modify voltage - they're basically glorified power strips, usually with monitoring (current draw, often environmental monitoring capability for temperature/humidity reporting), and sometimes with remote power switching capability. – voretaq7 Sep 16 '13 at 16:00
