UPS Power Supply Selection Guide
Everyone knows more about UPS power supply, that is, storing some electric energy through the built-in battery can ensure that electrical appliances can continue to run for a period of time when power is cut off. For computer users, the biggest function of UPS power supply is to protect the running systems and programs from sudden power failure, and at the same time protect the data that is not stored in time from being lost. UPS power supply is widely used in important industries (such as banking, finance, transportation and so on). ) and server system. But unfortunately, there are few reports on UPS power market in both print media and online media. Many friends came to ask how many products to buy these two days, because the prices of products in the market are too different. Is there any guarantee for cheap things? To this end, the author has done some research on the UPS market and will introduce some information to you today.
Of course, today we are talking about stand-alone backup UPS, which is the focus of PC enthusiasts' purchase. There are some cheap standby UPS in the market, and the price is only 200 ~ 300 yuan. This price is really very cheap for UPS products with very complicated circuits, including batteries, filter lines and inverse wave conversion lines. Therefore, most private buyers have to hesitate. Is it necessary to go to a specialty store to buy much more expensive products? At the same time, you will find a strange phenomenon. The price of UPS power supply of the same brand in ordinary counters is much cheaper than that in specialty stores, but there is basically no difference on the surface. Can such products be purchased? With these questions from readers, I consulted many friends in the industry and told you some answers today.
First of all, the standby UPS with very low price is really competitive in price, but everyone should know where its cost savings are. According to the author's understanding, this kind of cheap products will generally omit the filter circuit and voltage stabilizing circuit, and will also choose cheap products on key components such as maintenance-free batteries. It is particularly worth mentioning that the batteries used in some cheap UPS products are not specially made for standby UPS products, but are modified with batteries for other purposes. Under such circumstances, although the cheap UPS is very competitive in price, the quality and performance of its products will be greatly reduced. To be sure, such products are likely to have higher profit margins, and of course the damage to consumers is also the greatest. Besides, the brand UPS power supply with wide price difference lies in the maintenance-free battery used by UPS. Maintenance-free battery is the most important part of UPS power supply, and its cost is also the highest in the whole product. However, in order to make illegal profits, some businesses often replace the maintenance-free batteries in middle and high-grade UPS power supplies with batteries of miscellaneous brands or counterfeit brands, and then sell the maintenance-free batteries of this brand UPS power supplies separately. The profit of this exchange is quite amazing. Just as we all know that mobile phone batteries are stolen, why are the mobile phones in those humble shops cheaper than those in big stores, but the original accessories they sell are not cheap at all? This is the problem. The damage caused by inferior batteries is serious, mainly manifested in short inverter time and insufficient power supply. People often underestimate this problem, because non-professional users rarely use inverter power supply, so they will not deliberately test the inverter time of UPS power supply. But after a long time, the problem will be complicated, and the battery problem will gradually emerge, which will eventually lead to UPS failure. At this time, users who are unwilling to throw away the old power supply and buy it again will generally buy a maintenance-free battery, so that the genuine JS will have a chance to sell. Maybe you went to the old shop where you bought the power supply, and bought the battery that you bought from you a few months ago. To make matters worse, some users still buy fake batteries, and some even think that batteries need to be replaced from time to time. You can think it over. The so-called "maintenance-free" means that it can be used for a long time without problems.
In addition, at present, the famous household standby UPS on the market generally provides a set of power management software, so you can operate your products very clearly. At the same time, some brand-name products have built-in network and telephone line lightning protection functions, so that your system is free from "disaster." Of course, the convenient maintenance provided by brand power supply is also very important for UPS products, which can avoid a lot of troubles.
Through the above analysis, you should know something about the "shady" UPS power market. Sometimes spending less money may not be done well, and the final result is often greater losses. On the issue of computer accessories, you should bear in mind that "it is better to buy than to sell". The profiteers in Zhongguancun are popular because they have very limited knowledge of most ordinary computer users and are easily cheated by businesses. However, I also want to tell you a "coup" to avoid being deceived: always pay attention to the reports on this site. After all, we know more than our friends, so we have an obligation to break the maze for you. All right, cut the crap. Everyone must be anxious to know which brands are trustworthy. Which companies can we go to buy? Let me introduce it to you. You can go directly to the store to choose when you buy it, of course, the price is fixed.
+0) APC company. This is a well-known company that provides uninterrupted power supply, and its products are very complete: APC Silcon DP 300E series UPS is suitable for the protection of large data centers; APC Silcon DP 300E UPS series provides a good choice for products from desktop to enterprise. Back-UPS 500 series is the first choice for low-power users. At the same time, APC also provides the choice of power array.
2) Santer Company. Suntech TG 1000 is a UPS product specially designed for PC users, and its popularity is very high among similar products. TG series is also the main product of Santer company, which occupies a large share in the current market.
3) Shida Company. Shida launched "Little Sun 500" with low power consumption for household UPS market, which is a good choice for household users.
4) Delta Company. In the competition of this type of market, Delta's product is backup V-series UPS, which is also competitive.
Of course, there are other companies whose products also have stable performance, so I won't introduce them here. Finally, the author needs to remind everyone that the most important purpose of buying UPS products is stability. Therefore, you'd better choose in the specialty store of brand products, and don't trust the "enthusiastic" recommendation of the market counters, especially when the price is obviously lower than the market price. I hope you have a smooth sailing in the process of buying and using UPS.
