27 Jun 2022

Enterprise data centers are becoming more and more important nowadays. How to ensure the stable operation of enterprise data centers has become a very critical factor. UPS is a standard accessory for many enterprises in data centers, so how to choose a UPS power supply suitable for enterprise applications?


UPS classification:

In general, UPS systems are divided into three categories, backup (or offline), online interactive and double conversion (online). Different manufacturers will provide UPS with different configurations. Customers can choose the UPS they need according to their own goals, applications, and functional requirements, as well as their desire to differentiate their products.


How to choose UPS uninterruptible power supply

1.   First of all, you need to determine how much power the equipment in your data center needs. Generally speaking, the power of ordinary PC or industrial computer is about 200W, the power of Mac is about 300W, the power of server is between 300W and 600W, and the power of other equipment is about 200W. The power value can refer to the instruction manual of the device. Just buy as required.


2.   Secondly, it should be understood that there are two ways to express the rated power of the UPS: the apparent power (unit VA) and the actual output power (unit W). This difference is caused by the existence of reactive power. The conversion relationship between the two is: Apparent power * power factor = actual output power. So be careful when buying.


3.   UPS is usually divided into two types: power frequency machine and high frequency machine. The power frequency machine is composed of thyristor SCR rectifier, IGBT inverter, bypass and power frequency step-up isolation transformer. Because the working frequency of the rectifier and the transformer are both the power frequency 50Hz, as the name suggests, it is called the power frequency UPS.


Given these options, how should you choose your UPS configuration? We will discuss this on the next article!
