As the PDU suppliers, also visited and checked many units at the center of the room. Found that most of the units are attaches great importance to construction of center room power supply, UPS capacity load rate, double circuit power supply to the cabinet, do is specification. But also found that many institutions have ignored the cabinet internal devices of power supply connection details - use normal lug plate to do power adapter. Some cabinet because lug plate with hole is not enough, then cascading down layer by layer, figure 1 creates this kind of confusion. I also worked in a unit at the center of the room to see this situation: in a cabinet in the total power equipment has more than 4000 w, USES a 10. A, 250 v, 2500 w of ordinary household lug plate, but also connect the 3 layers, I can't imagine this room administrators can sleep.

   Room of the servers, switches, data storage and other electronic equipment are shoulders on the responsibility of the unit key business process, some even need 7 * 24 hours non-stop running, the computer room environment, such as air conditioning, cabinets, power demand more and more is also high. All equipment within the room, both the main equipment and auxiliary equipment must have a high reliability and availability. For the power outlet, this is the last line of all equipment utilization level if it is not stable, not enough protection function, it may lead to expensive electronic equipment have been destroyed, and even the collapse of the entire business system.

   You should use what kind of socket for the electricity power supply, the last line of the mark? The answer is: should use PDU. The abbreviation of PDU in English the Power Distribution Unit, namely the Power allocation Unit. This kind of rack is special power socket compared with ordinary power socket, its advantage mainly displays in: design arrangement more reasonable, the socket type variety, quality and standard is more strict, the safe trouble-free long working hours, all kinds of leakage, CLP overload protection function is all ready, even if is frequently plug is not easy to damage, and small hot temperature, more flexible and convenient installation, suitable for business customers to use of electricity is very strict. Also fundamentally put an end to the common power socket caused by poor contact, large load frequent power outages, fire, fire safety, etc. At the same time it also has flexible, easy to use and convenient intelligent management control functions, such as various advantages.
