APC is a well-deserved giant in the UPS industry. In the industrial-grade high-power UPS, APC is the world's top three manufacturers, and in the field of low-power UPS suitable for home use, APC is firmly in the first place.
 
Founded in 1981, APC is one of the most well-known small and medium power UPS brands in the world. After being acquired by the multinational company Schneider in 2007, it merged with Schneider's top UPS brand, Meilan Gerland, and became a well-deserved leader in the industry. In order to complete the merger and acquisition, Schneider even had to sell the UPS business below 10KVA in Meilan Gerland, so as to avoid the suspicion of monopoly and obtain authorization from the European Union.
 
Unlike other top manufacturers, APC has launched a complete line of low-power UPS products, which is well-known in the home market. In North America, Europe and China, APC is the most recognized brand by families and individual users.
 
In addition to providing basic power-off protection, only a small number of backup UPSs have voltage stabilization functions. Different from the high-quality sine wave power supply of the mains, when the power is off, the backup UPS can generally only provide square wave power supply, and the power quality is not high. However, due to the fact that the square wave power supply can hardly affect the computer and NAS (network storage server) and other equipment in a short period of time, the backup UPS is very suitable for home use.
 
APC's most well-known backup UPS is the BK650, which has a maximum load of 400W, which is enough to power devices such as home computers. The most outstanding feature of the BK650 is that it can automatically shut down the NAS when the power is off when it is unattended. Even though many measures have been taken to protect the current hard drives, data loss due to sudden power outages still occurs occasionally, so it is necessary to configure an uninterruptible power supply for the NAS. The price of BK650 is only about 500 yuan, which is currently the most commonly used equipment for NAS in China. Another BX650CI-CN with similar functions has a better construction and workmanship than the old BK650, and the price is about 600 yuan.
 
Online Interactive UPSs are another type of UPS suitable for home use, and all Online Interactive UPSs can provide voltage stabilization (AVR) function compared to backup types. Since the general online interactive UPS can provide analog sine wave power supply, the power supply quality is better than that of square wave. In areas where the power quality is unstable (such as industrial areas and old residential areas), UPS with AVR function is more suitable.
 
APC's online interactive representative is the BACK UPS Pro series. In addition to the similar power management software to the BK650 to protect NAS and desktop computers, the biggest feature of the BACK UPS Pro series is that it is equipped with a display screen that can monitor the power of the UPS load equipment in real time, battery life and voltage conditions, etc.
 
The BACK UPS Pro series is available in 550VA, 1000VA and 1500VA models, corresponding to loads of 330W, 600W and 865W. In general, it is more appropriate to choose the corresponding UPS product according to 1.5 times the total power of the protected equipment. For example, if the total power of the desktop monitor is 200W, then when choosing a UPS, the maximum power of 300~400W is more appropriate. According to the model difference, the price of BACK UPS Pro series ranges from 800~2000 yuan.
 
Not only in the field of low-power UPS, APC is also one of the most powerful high-power UPS manufacturers. On enterprise-class high-power UPS, APC's Smart Online series is one of the most suitable UPSs for networks and servers. For the large-scale equipment field of data centers and industrial manufacturing equipment, APC also has the Galaxy series inherited from MGE Meilan Gerland. The coverage of the whole field of high power and low power makes Schneider's APC the most powerful competitor for the world's best UPS brand.
