LEARNING ABOUT THE UPS

UPS is an acronym for Uninterruptible Power Supply in Vietnam also known as UPS. The UPS is used to provide power for a short or long period of time depending on the UPS's capacity to maintain the operation of electrical and computer equipment in the event of an electrical failure.

T.A.T is pleased to share with you about this UPS (UPS) by concept, UPS classification, what UPS offline is, what is UPS online is and choose the right UPS as follows:

 

1. UPS concept

The operation of the UPS is based on the conversion of DC voltage from a battery to a bidirectional current to meet the requirements of the computer. The main function of the UPS is to backup power but on the other hand, the UPS can Additional features such as anti-pulse, lightning protection, frequency stabilization ...

 

2. UPS Classification

UPS has two main lines: UPS offline and UPS online. In which UPS is offline including simple universal UPS and UPS with Line-interactive technology.

 

3. Offline UPS

Standard UPS Offline is the most popular product line on the market today and is cheaper than Line Offline technology that supports Line Interactive technology. The operating principle of standard Offline UPS is that the input power grid passes through the switching switch before supplying the load. The UPS now only uses the charger to fully charge the battery. In case the grid is unstable (too high, too low or power is out), the UPS will automatically switch (via relay), using power from the battery supplied to the device to maintain operation.

Operation principle of Offline UPS Line Interactive Technology is similar to standard UPS Offline line but has more voltage regulator circuit to adjust output voltage for stable load. In case the voltage is too high or too low, Offline UPS Line Interactive technology, the voltage stabilizer circuit automatically switches to another level so that the output voltage ensures the correct load as required.

The UPS Offline design is only suitable for use in office equipment and computers; devices with pure load properties. The slow switching time of the UPS Offline series is quite slow, about 10 ms (milliseconds), and cannot extend the time stored by internal and external storage batteries. The standard UPS Offline does not support voltage stabilization function.

 

4. UPS online

Completely overcome the disadvantages of UPS Offline series, UPS Online series with Online Double Conversion technology, eliminating the problem of grid electricity because the input voltage is always modulated before being used for download. Grid power is not supplied directly to the device but is converted into DC current for battery and inverter (Inverter). The inverter will continue to convert the received DC current into an output voltage suitable for the device used. So it can be seen that when any problem occurs in the grid, your device is always safe.

 

UPS Online series is usually designed with large capacity, can extend the time of battery storage with internal and external storage battery, so in addition to devices with pure load nature such as office equipment, computers UPS Online can also be used for server systems, data centers and even devices for loading engines such as fans, pumps, etc.

 

5.  Choose the right UPS

Determining the usage demand, usage time and total capacity of the device are the criteria to consider to choose the right UPS. For example, with a personal computer in the office or in the home, choose the UPS Offline line. With server system or data center, Online UPS is a top priority.

 

In addition, if you need to extend the use time to complete the backup or turn off the system properly, you should choose a UPS with battery storage (internal or external). In addition, some UPSs have built-in management software to help users monitor their operating status and manage UPS more flexibly and reliably when power grid is lost.

Choosing UPS is not difficult but the problem many readers have is the lack of product information or incorrect advice. Ideally, you should seek help from the company's technical support or official distributors for advice and appropriate options.
