A lot of people don't know what cabinet PDU, actually rack PDU is cabinet POWER socket, cabinet dedicated socket is often referred to as PDU, full POWER - in English
分布,
UNIT, which means the power distribution UNIT.
PDU is generally designed for 19 'standard rack, it adopts modular structure, main is to ensure that the cabinet in communications, electronics and other important equipment of power supply, avoid the equipment damage caused by over-voltage and lightning induction.
Although PDU is a small device, but it is all sorts of equipment in the work the longest devices, as long as there is equipment work, PDU in working condition.
If the quality is bad, PDU power is likely to cause fire, even the loss will be immeasurable.
So choose the high quality high performance network cabinets dedicated power distribution unit to further ensure the safety of the system work is how important it is to imagine.
1, lightning protection, surge protection: the maximum impact resistance: 20 ka or higher;
Low limit voltage: 500 v or more or less.
2, alarm, protection: LED digital display with alarm function of the entire current monitoring. 3, filtering protection: with a fine filter protection, output hyperstatic pure power supply. 4, overload protection, overload protection, provide poles which can effectively prevent overload problem. 5, prevent wrong operation: PDU master switch ON/OFF grid belt protection, can prevent the accident shut down, at the same time provide alternative double way. 6, modular design, equipped with international standard socket, British standard socket, din sockets, socket and so on different modules can be free replacement in order to meet the different needs of customers. Cabinet PDU power distribution unit, of course, but also has such as wide use range, high mechanical strength, the use of safe and reliable, and so on edge! The choice of PDU 1. In general column header tank distribution of branch circuit power + safety margin = pdus on this line of power sum.
2。 A machine cabinets + safety margin = all pdus contained in the number of devices, the number of sockets if dual redundant lines the PDU parameters need to be doubled.
3。 For large power equipment we should try to spread the different PDU in order to balance the phase current.
4。 On the basis of the plug the power cord can't separate equipment standard to customize the PDU groove, once the power cord can separate equipment can take to replace the power cord to solve when plug is not compatible.
5。 Cabinet equipment in high density, PDU it is advisable to choose multiple tap vertical loading, low density inside the cabinet equipment, PDU it is advisable to choose less jack lateral finally to quote PDU separate budget in order to avoid a serious shortage of budget.
6。 When choosing PDU should choose regular professional manufacturers of products. Because of the PDU is good or bad influence on the rack is very big. May be affected by any carelessness will cause irreparable consequences.
7。 Choose the PDU is premise of normal manufacturer, at the same time also need about national certification testing, can be at ease use. Home with three flat and gb gb multi-purpose socket.
