UPS

The uninterruptible power supply (UPS) converts the DC voltage of the battery or battery pack into AC voltage according to the required amplitude and frequency to ensure the continuity of the power supply in the event of a power failure.

According to application requirements, UPS can be constructed through simple offline configuration, or through online double conversion for high-end, medium, and high-power UPS, which can also improve the sensitivity to sensitive loads (including computers, servers, industrial process equipment, instruments, and meters). And telecommunications equipment).

USP  Availability

Increasing availability requirements of data processing centers. Promote the continuous development of UPS configuration. “Availability” is an estimate of the percentage of time that the power supply remains powered and operating normally to support the critical load. The usability value in this article is higher than the usability in the actual application, for easy comparison.

USP Grade

All UPS systems (and power distribution equipment) require regular maintenance. On the one hand, the availability of the system depends on the configuration not being affected by equipment failure, on the other hand, it depends on the ability to perform normal maintenance and maintenance to ensure the power supply of critical loads.

UPS  Configuration Budget

Most customers said that redundancy, scalability, modularity, and maintainability are key decision factors for their purchase of UPS. Therefore, most sales staff regard the above factors as the key content of their sales proposal. However, if the customer’s budget and important factors in the purchase decision are not fully considered in advance, the sales proposal may be in a disadvantaged competitive position.

The higher the availability level of the configuration, the higher its cost. This cost refers to the cost of building a new UPS system. Therefore, it includes not only the cost of the UPS structure but also the cost of the entire network critical physical infrastructure (NCPI) for data management.

The latter includes generators, switchgear, refrigeration systems, fire protection systems, raised floors, racks, lighting facilities, physical space, and commissioning costs for the entire system. These are only upfront costs and do not include operating costs, such as maintenance and maintenance costs.

When calculating the above cost, we assume that each cabinet has an average floor area of ​​2.79m2, and the power density ranges from 23kW to 3.8kW per cabinet. If the cost-sharing equipment area increases, the cost per rack will also decrease.

For a long time, when planning critical load power supplies, future development must be fully considered, so that the UPS system can provide 10 or 15 years of support for the load.

Facts have proved that planning in accordance with this principle is very difficult. In the 1990s, in order to provide a framework for discussion and compare various facilities, the concept of “watts per square area” was proposed. However, because people cannot reach a consensus on the meaning of “square area”, this power supply design index has caused many misunderstandings.

Recently, with the general trend of technology simplification, people have gradually adopted the concept of “Wat Yin Cabinet” to express system capacity.

Facts have proved that since the number of racks in a unit space is easy to count, this calculation method is more accurate. Regardless of the choice of load method, it is important to choose the configuration scheme from the beginning so that the design process proceeds in the right direction.

Nowadays, many scalable modular UPS system designs have emerged, so that UPS power capacity can be expanded with the growth of IT demand.

Uninterrupted power supply, comprehensive improvement of power supply quality, and an end-to-end comprehensive protection scheme for the entire network from equipment to data transmission are inseparable from the UPS power supply system. So it can be seen that the UPS design considerations are very important. The following specific instructions are for the UPS design attention matter.

UPS Design Elements

   1. Power supply environment: single-phase and three-phase

In the evaluation process, it is important to grasp the customer’s existing power supply infrastructure. While most sales consultants usually focus on large three-phase power systems, IT managers often involve rack-level equipment. Many existing computer rooms and small and medium data centers are equipped with rack-level to single-phase loads.

In order to improve efficiency, reduce costs, and create more sales opportunities for the newly implemented three-phase solutions, various new designs have shifted the focus from three-phase power supply to utilization.

   2. Installation environment

Be sure to understand the future deployment requirements of USP. Because most environments can support multiple different solutions, you need to help customers evaluate this. Be prepared to propose value propositions, feature comparisons, and quotes for multiple solutions.

Research shows that customers generally choose a program with a higher value. If it is not possible to provide multiple solutions, it can provide another more cost-effective solution, introduce other products to fair competition, and gain the trust of customers.

  3. Power load

The rated power of the customer’s power load is the most important factor in determining a suitable UPS for its overall solution. After clarifying the power environment (such as single-phase or three-phase UPS), the UPS specification selection range can be further locked. Although many customers already have this kind of information, you still need to assist customers to complete the selection of power equipment for their equipment.

Be sure to consider the potential growth demand of the customer’s power load. Especially in the deployment of single-phase equipment, it is usually necessary to select a UPS that exceeds the current power requirements of the customer but can provide a longer running time, so as to meet future growth needs.

   4. Usability

Availability refers to determining the true uptime requirements of customers. Running time seems to be simple to quantify, and understanding the true meaning behind these numbers helps to develop a complete end-to-end solution. Usually, the amount of runtime required directly affects the cost of the solution.

But in fact, most solutions are more cost-effective and efficient in applications that extend runtime. It is important to understand how long the customer needs to run and understand the real reason. A comprehensive evaluation of multiple solutions is required when providing professional advice to end-users.

   5. Scalability

When evaluating a solution, the most important thing is to consider the customer’s future expansion needs. Scalable UPS solutions have a competitive advantage and can provide customers with a cost-effective capacity improvement program. In fact, all UPSs with a rated power of 6kVA or higher can be expanded and upgraded through simple firmware upgrades, adding modular hardware components, or connecting multiple UPSs in parallel.

For customers who pay attention to cost or budget, time can usually prove the best value of UPS with inherent scalability, and customers can increase capacity without purchasing additional hardware facilities. A simple power upgrade can make the UPS with built-in scalability obtain the maximum capacity.

For customers who have IT personnel or equipment management staff and maintain equipment by themselves, as the power load increases, they prefer to increase capacity by purchasing additional modules that can be added to expandable cabinets or racks.

Although it is usually a more economical option to purchase modular solutions with multiple parallel systems in the early stage, in the long term, these solutions may actually be more expensive due to rising hardware and installation costs. According to the specific needs of customers, a large-scale centralized non-modular system with inherent scalability may be the most cost-effective solution.

   6. Power distribution

Be sure to understand the customer’s power distribution plan. Remember that Eaton has larger three-phase PDU and single-phase PDU products (including ePDU and rack power modules), which can be used with any UPS products. Just as software, communications, and meter measurement equipment can usually be sold as hardware, a complete power distribution and meter measurement solution can directly meet customer needs, and then finally sell the solution.

In some instances, data center managers hope to monitor the situation of departmental resources more effectively, so as to help companies better allocate human resources. When deploying meter measurement equipment to the rack level, users of our product solutions can track the needs of each department and allocate various expenses based on meter readings. In addition, analyzing the peak hours of computing process usage and the most effective available servers can help IT, managers, to further improve overall efficiency.

  7. Manageability

The highly manageable software and accessory products we provide usually help our hardware sales, and maybe the key to closing sales. Highfive’s management software tools should be introduced as much as possible in each sales opportunity to help customers develop solutions and reduce the overall cost of ownership.

If the customer claims that the remotely managed device is about 10 minutes away, it will take 15 minutes to run. In view of the difference in the ability of sales staff to recognize the real needs of customers, it is recommended to use network interface cards suitable for rack-mounted UPSs and be equipped with remote management software to ensure that the UPS can properly shut down these applications in the case of expansion interruptions. In addition, ePDU can also be used to achieve multi-level monitoring.

In the event of a power outage, the customer can remotely monitor the UPS and restart the server without rushing to the site-the customer has therefore purchased all the hardware devices that implement the above functions. After mastering the customer’s communication and control needs, Eaton can provide customers with a full range of solutions.

   8. Operation and maintenance

Many customers attach great importance to the ability to maintain equipment, and most IT personnel and equipment management experts prefer to turn to on-site factory support services.

Mastering the availability requirements, technical capabilities and risk tolerance capabilities of customers is an important part of the advisory sales process, which can further reduce the scope and number of product choices. In addition, the upfront cost of the product and Eaton’s service level agreement should also be considered as important sales links.

Some IT experts are concerned about whether they can switch modules independently or replace the batteries used in their products, while other experts like to use delivery solutions to power their data centers.

In addition, the installation method (decentralized or centralized large UPS) may also affect customers’ preference for service selection. For some customers who want a high degree of service autonomy, it may be the most ideal solution to select small single-phase or rack-type equipment that allows users to replace batteries and modules by themselves.

Customers who prefer economy and higher rated power may prefer a low-cost centralized EOR solution with on-site support provided by the factory. In the process of implementing advisory sales, accurately predicting the budget and technical support needs of your customers can help you do more with less.
