With the rapid development of the information age, it is now very common for small and medium-sized enterprises to equip UPS to prevent data loss. For UPS power supply, we generally divide it into backup, online, and online interactive based on its working principle.
The backup UPS has the most basic and important functions of automatic voltage regulation, power outage protection, etc. It generally has a conversion time of about 10ms. The AC output from the inverter is a square wave rather than a sine wave, and due to its simple structure, it has the advantages of low price and high reliability. Therefore, it is widely used in fields such as microcomputers, peripherals, POS machines, etc;
Online UPS has a complex structure but complete performance, and can basically solve all power supply problems. Its notable feature is that it can continuously output pure sine wave AC power without interruption, and can solve power supply problems such as spikes, surges, and frequency drift; Due to the need for significant investment, it is usually applied in environments with strict power requirements such as critical equipment and network centers;
Online interactive UPS, compared with backup UPS, has filtering function and strong resistance to mains interference. The conversion time is less than 4ms, and the inverter output is analog sine wave. Therefore, it can be equipped with network equipment such as servers and routers, and is generally used in areas with harsh power environments.
The function of UPS products is to ensure, and for users, UPS is often the last line of defense to protect equipment and data security. Compared to other products, reliability and quality are of greater significance to UPS.
How can small and medium-sized enterprises select power products that are suitable for their application needs from UPS products? Grasping the four aspects discussed below may be helpful for small and medium-sized enterprises when choosing UPS products and solutions.
1、 Reliability
The reliability of UPS has always been a focus of user attention. The proportion of UPS failures caused by human factors is very high. Parallel redundant systems can not only be expanded and upgraded, but more importantly, they can greatly improve the reliability and availability of the system. In addition, in large and medium-sized central data centers, using a single UPS for protection can no longer meet the requirements of the system, so redundant solutions have emerged. The N+X parallel redundant system can maximize the power supply of the system.
2、 Intelligence, networking, and overall integration
With the growing development of Internet applications, "network UPS" has become a development trend. Through the network, management personnel can remotely monitor the operation status and parameters of UPS. When the battery runs out, they can safely shut down the operating system of servers and terminals, and save a lot of management costs and funds. With the popularization of network intelligence, the intelligence of UPS is also an inevitable development trend, such as sending various information codes of UPS to relevant network management personnel through communication devices such as email and mobile phone.
Intelligent UPS can not only diagnose various faults of its own, but also automatically adjust and set corresponding operating modes according to different application scenarios to meet different needs. With the increasing demand for centralized applications from users, a complete set of solutions from the mains entrance to the load end can better meet users‘ requirements for high reliability. The power protection system extends to all power supply links of the entire power system, thereby achieving high availability of the network. Therefore, end-to-end power protection solutions have become the latest development trend.
3、 Miniaturization and high efficiency
From a product perspective, UPS is developing towards smaller size, lighter weight, and easier use. The requirements for UPS input power factor and efficiency are gradually increasing. Data centers can be described as "every inch of land, every inch of gold". The density of machines is very high, and it is necessary to effectively solve the efficiency problem of UPS. UPS using high-frequency technology can effectively improve the input power factor of the power supply, reduce harmonic pollution, reduce power loss, improve system efficiency, and significantly reduce the volume and weight of UPS. When choosing UPS, don‘t be fooled by low prices, be sure to grasp key indicators.
4、 Product quality and after-sales service
When choosing UPS, product quality and after-sales service assurance are also very important to ensure that the purchased power system can receive long-term and comprehensive service.
