PDU power socket is the last pass for all equipment in the machine room cabinet. It is the gatekeeper of all equipment and systems in the enterprise. If its stability and security are not good, it will bring serious loss of equipment damage and even system collapse. At the same time, PDU shoulders the responsibility of enterprise operation supervision. It not only undertakes the distribution of power supply, but also has the management function of power supply. According to the functions and requirements of power supply environment required by enterprise operation, PDU can choose different installation methods and plug-in combinations of various series specifications to meet the power demand of equipment in cabinet.
As the value of PDU is gradually widely recognized, the selection and demand of PDU vary from the national data center to the single cabinet of small and medium-sized users. Especially for the small and medium-sized computer room users, the group base is huge and there are many risks. Therefore, more professional, fast and convenient purchasing entrance is needed. So in the face of many PDU products on the market, how to choose the most reliable PDU The following purchase strategies are worth referring to:
1. Reliable pre-sale service. We often say that only feet know whether shoes are comfortable or not. However, in the face of the risk of expensive equipment and system collapse, we must put an end to uncomfortable experience. Therefore, reliable pre-sales service is an important indicator to measure whether a PDU manufacturer is professional. Often, without professional guidance, problems such as failure to use electricity, insufficient power matching, poor grounding, even burning equipment, power supply line interruption and other problems may easily occur in the later use process. If the equipment is not handled properly, it is likely to pay a painful cost in the later stage
2. Reliable products come from regular manufacturers. The scale, strength, volume and qualification of an enterprise are all used to measure whether an enterprise is formal or not. However, it should be noted that formality is not equal to specialty. Some regular manufacturers are not specialized in producing PDU products, or PDU products are not their superior products. This requires enterprises to consider the reputation of the brand in the industry, whether there is an independent design team and professional production team, design experience and production capacity, as well as the specifications of specific products.
3. Reliable not only pre-sale but also after-sales service. No matter how good the product is, no one can guarantee that there will be no bad time, so after-sales service is also a key issue. For a special product like PDU, if the matching experience value of power consumption for equipment in the computer room is an important guarantee for pre-sale service, then the service life of the manufacturer is not only an important indicator to judge the professional degree of the manufacturer, but also the basis for whether it can provide continuous and stable after-sales service.
Small and medium-sized computer rooms, choose the appropriate and stable PDU, not only ensure the normal operation of the computer room, win the trust of users, but also avoid the loss of human, material and financial resources caused by frequent maintenance in the later stage.
Planning and selection
In many computer room bidding, PDU and UPS, cabinet, cabinet and other equipment are not listed separately. PDU parameters are not clear, and even some are just marked with power strip, which will cause great trouble to the later work: unable to match with other equipment, non-standard power distribution, serious budget shortage, etc Labeling requirements PDU? Here?s a simple way to do it
1) What is the total power. The circuit power of the distribution branch of the column head cabinet + safety margin = the total power of PDU on this line;
2) Input mode. Such as with cable, plug, professional junction box, terminal box, etc.
3) Input current. AC or DC? Input current? Generally, there are 10a, 16a, 32a, 63A, etc. The rated current must be greater than
The sum of the input currents of the connected devices. The high-power equipment should be dispersed in different PDUs as far as possible to balance the phase current, and the total current of each PDU is calculated;
4) Number and specification of socket holes. The number of devices in a cabinet + safety margin = the number of sockets of all PDUs in the cabinet. If there are dual redundant lines, the number of PDUs should be doubled with the parameters. The output socket module has national standard, American Standard, international IEC, German standard and so on.
5) Features. Such as adding power indicator, master control switch, lightning protection function, overload protection, current and voltage display, remote monitoring function, online detection of smoke temperature and humidity, etc.
6) Installation method. The density of the equipment in the cabinet is high. It is appropriate to use multiple sockets for vertical installation of PDU, and it is appropriate for PDU to select fewer sockets for horizontal installation. Finally, a separate quotation budget should be given for PDU to avoid serious budget shortage.
