Detailed UPS power supply for SMEs

With the rapid development of the information age, it is now very common for SMEs to equip UPSs to prevent data loss. For the UPS power supply, we generally divide it into backup type, online type, and online interactive type according to the working principle.

Backup UPS has automatic voltage stabilization, power failure protection, etc. This is the most basic and most important function of UPS. Generally, it has a conversion time of about 10ms. The AC power output by the inverter is a square wave instead of a sine wave. It has the advantages of cheap price and high reliability, so it is widely used in microcomputers, peripherals, POS machines and other fields; 

The structure of online UPS is more complex, but its performance is complete, which can basically solve all power problems. Its outstanding feature is that it can continuously output pure sine wave AC power without interruption, and it can solve power problems such as spikes, surges, and frequency drifts. Large investment, usually used in critical equipment and network centers, such as demanding power environments; 

Online interactive UPS , compared with backup type, online interactive type has filtering function, strong anti-interference ability, conversion time is less than 4ms, inverter output is analog sine wave, so it can be equipped with server, router and other network equipment Used in areas with severe power environments.

The function of UPS products is to guarantee. For users, UPS is often the last line of defense to protect the safety of equipment and data. Compared with other products, "reliability and quality" is more important to UPS.

How do small and medium-sized enterprises choose a power supply product suitable for their application needs from UPS products? Grasping the four aspects described below may be helpful for SMEs when choosing UPS products and solutions.

1 Reliability

UPS reliability has always been the focus of attention of users. 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 the large and medium-sized central data room, the use of a single UPS for protection can no longer meet the system requirements, so a redundancy scheme has surfaced. The N + X parallel redundant system can maximize the system's power supply.

Intelligent, networked, integrated 

With the increasing development of Internet applications, "network UPS" has become a development trend. Through the network, the management personnel can remotely monitor the operating status and operating parameters of the UPS, and can safely shut down the server and terminal operating systems when the battery is exhausted, and can save a lot of management costs and funds. With the popularization of network intelligence, the intelligentization of UPS is also an inevitable development trend, such as sending various information codes of UPS to related network management personnel through email, mobile phones and other communication equipment.

Intelligent UPS can not only diagnose various faults of itself, but also can automatically adjust and set the corresponding operation mode according to different applications to meet different needs. As the user's centralized application needs continue to increase, a complete set of solutions from the mains entrance to the load end can better meet the user's requirements for high reliability. The power protection system extends to all power supply links of the entire power system, thereby achieving high network performance. Usability. Therefore, end-to-end power protection solutions have become the latest development trend.

Third, miniaturization and high efficiency 

From the perspective of products, UPS is moving 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 "inch-inch-inch-inch". The machine density is very large, and the efficiency of UPS must be effectively solved. UPS using high-frequency technology can effectively increase the power input power factor, reduce harmonic pollution, reduce power loss, and improve system efficiency. Significantly reduce the size and weight of the UPS. When choosing a UPS, don't be fooled by too low a price, be sure to grasp the key indicators.

Product quality and after-sales service

When choosing UPS, product quality and after-sales service guarantee are also very important to ensure that the purchased power system can get long-term and perfect service.
