What is a UPS?
UPS stands for uninterruptible power supply, and it comes into being as a result of the fast development of computer and telecommunication equipment. It is a piece of important peripheral equipment for electronic information system, and it takes advantage of an inverter, an energy storage device and other components to offer continuous power supply with stable voltage and frequency.
Technically speaking, we can describe what a UPS is in three aspects as listed below.
1. Theory: A UPS is a power electronic device that integrates digital circuit, analog circuit, automatically controlled inverter and maintenance free energy storage device together.
2. Function: A UPS could effectively correct utility power problems if there are any, and it can provide emergency power to computers or other loads for a continuous time period when the mains supply fails, allowing the user to deal with current work in no hurry.
3. Application: As required by the information-based society, UPS has been widely used in different stages of data processing, including collection, transfer, storage, application, etc.
Why UPS is commonly used?
UPS units are capable in varying degrees of solving common mains supply problems, such as noise, power failure, voltage spike, sustained overvoltage, low input voltage and others. Thus, they usually work as backup power supply for computers, servers, computer network systems and different kinds of high precision electrical equipment to guarantee their normal working when mains power fails or other problems take place.
This product plays a very important role for computers and many other electrical appliances, and it will become more and more popular in our daily lives.
