How to buy PDU power socket?
PDU power socket as the last gateway 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 is not good, it will bring equipment damage to the enterprise, and even the system collapse of the serious losses. At the same time, PDU shoulders the responsibility of enterprise operation supervision, it not only undertakes the distribution of power supply, but also should have the function of power management. According to the functions and requirements of the power environment needed for enterprise operation, PDU can choose different installation methods and a variety of series of specifications for the combination of plugs to meet the power needs of the equipment in the cabinet.
As the value of PDU is gradually being widely recognized, from national data centres to small and medium-sized users of individual cabinets, the choice and demand for PDUs are also different, especially for small and medium-sized server room users, the group base is huge, with a lot of risks and hidden dangers, which requires a more professional, fast and convenient shopping portal. So in the face of the many PDU products on the market, how to buy the most reliable PDU? The following points are worth referring to the shopping strategy:
1. Reliable pre-sales service:
We often say that only the feet know whether the shoes are comfortable or not, however, in the face of expensive equipment and the risk of system crash, we must eliminate the uncomfortable experience, therefore, reliable pre-sales service is an important measure of the professionalism of a PDU manufacturer. Often the case is that, in the absence of professional guidance, in the later use of the process is very easy to equipment can not power, power matching is not enough, poor grounding, or even burn equipment, power supply line interruption and other issues, improperly handled, it is likely that you will pay the late tragic costs.
2. Reliable products from regular manufacturers:
Enterprise scale, strength, volume, qualifications, etc. are used to measure whether the enterprise is a formal standard, but it should be noted that the formal is not the same as professional, some of the formal manufacturers are not professional manufacturers of PDU products, or PDU products are not its advantageous products. This requires companies to choose products in the process of comprehensive consideration of the brand's reputation in the industry, whether there is an independent design team and professional production team, design experience and production capacity as well as specific product specifications and other dimensions of the consideration.
3. Reliable not only pre-sales but also after-sales service:
Even better products, no one can guarantee that there is no bad time so after-sales service is also a key issue. For PDU such a special product, if the matching experience value of the equipment in the room is an important guarantee of pre-sales service, then the manufacturer's years of experience is not only an important indicator of the professionalism of the manufacturer, but also whether it can provide continuous and stable after-sales service basis.
Small and medium-sized server room, selected to the appropriate and stable PDU, not only to ensure the normal operation of the server room to win the trust of users, but also to avoid the loss of manpower, material and financial resources caused by frequent maintenance.
Planning and Selection
Many computer room bidding and PDU and UPS, column header cabinet, cabinets and other equipment as a single column, the requirements of the PDU parameters are also very unclear, and even some are just marked power strip only, which will cause a lot of worry about the work of the later stage: that is, can not match with other equipment, non-standard power distribution, the budget is seriously insufficient, etc. The main reason for this phenomenon is that both sides of the bidding is not clear how to mark the requirements of the PDU? Here Qunfang technology gives you a simple method:
1) how much total power: column header cabinet distribution branch circuit power + safety margin = the sum of the power of the PDU on this line:
2)Input method: such as with cable, with plug, professional junction box, terminal junction box, etc..
3)Input current: e.g. AC or DC? Input current size? Generally 10A, 16A, 32A, 63A, etc. The rated current must be greater than the sum of the input current of the linked equipment. Distribute high-power devices in different PDUs as much as possible to balance the current of each phase: Calculate the total current of each PDU;
4) The number of socket holes and specifications: the number of devices in a cabinet + safety margin = the number of holes plugged into all the PDUs in the cabinet, if there are dual redundant lines, the number of PDUs should be doubled with the same parameters. Output socket module has national standard, American standard, international EC, German standard and so on.
5) Functional components: such as increasing the power indicator, master switch, lightning protection, overload protection, current and voltage display, remote monitoring functions, smoke detection, temperature and humidity online detection.
6) Installation: high density of equipment in the cabinet, the PDU selection of multi-jack vertical installation is appropriate, low density of equipment in the cabinet, the PDU selection of fewer jacks installed horizontally is appropriate, and finally to give the PDU a separate offer budget to avoid serious budget shortfalls.
