1. What is a UPS?
Uninterruptible Power Supply (UPS) is a backup power storage device that plays the role of providing power for a period corresponding to the design capacity to maintain uninterrupted operation of electrical equipment. when there is a power failure. From there, avoid causing serious losses in many aspects such as: data loss, production delays, failures, high costs to restart production lines… for factories and businesses.
2. Classification of UPSs on the market
On the market today, there are many UPSs with different technologies, notably UPS lines with Online, Offline, Line-interactive technology.
+ With Offline UPS technology: This is the longest existing UPS technology on the market today, the UPS usually gives power at the output with a simulated square wave or sine wave, different from new technology UPS lines. for a standard sine power supply. The power generated by the Offline UPS is often unstable and has a high error rate. Besides, the backup time of this device is relatively short, the switching time between operating modes is usually 4 – 10ms delay. With Offline UPS technology, UPSs often have small capacity and limited expansion functions.
+ UPS Line – interactive technology: This is a UPS technology developed following Offline UPS technology, Line – interactive UPS technology for better efficiency and overcome some disadvantages of Offline UPS. such as: stable output voltage, small voltage change range. At the same time, the output electrical waveform is also better changed, switching from square waveform to simulated sine waveform.
+ Technology UPS Online: This is the most recently developed new technology and is widely used on UPS UPS until now. This UPS with Online technology overcomes almost all the disadvantages of the previous two UPS technology lines
The UPS Online series can provide clean, standard sine output power, reduce harmonics, and the output voltage is extremely stable and has a very small error. At the same time, the voltage frequency is also very stable, with an error of 0.1%. But the most outstanding improvement feature is that the switching time between the operating modes of the UPS is almost 0ms. More functions, support for smart slots, smart control… Besides, the power storage time of the UPS is significantly improved and can be customized. With this technology, the UPS is applied to the product lines with medium and large capacity.
3. Features of UPS
UPS will bring special features for users:• Limit noise and output harmonics: the UPS performs filtering of the output source before supplying to the load
• Stabilize output voltage and frequency: voltage and frequency stabilize the load to a set value, the error is very small
• Standard sine output voltage: standard sine voltage is almost the same as the grid
• Stable operation, high reliability
• Very good system performance
• Integrated many smart functions: integrated monitoring card, functional terminals…
4. What is a UPS used for?
The UPS will help a production line continue to operate while waiting for backup power to start up, the computer can operate stably to save data and perform tasks.
In addition, the UPS also helps the server system to be safely shut down. The monitoring, warning, internet, and camera systems can continue to work even if the grid has a sudden power failure.
UPS helps to avoid serious losses in many aspects such as: data loss, production delays, machine breakdowns, high costs of restarting the line, avoiding reduced equipment life and replacement cost of new components.
Besides, it also reduces maintenance costs, investment costs of backup power systems for businesses and production plants.
5. Application of UPS
+ Applications in the machine room – server: Computers and servers are devices that store important data of companies and businesses. Therefore, it is very necessary to have a UPS to help these machines not be cut off suddenly leading to damage as well as loss of important data.
+ Application in industrial production: Industrial workshops often operate with a large number of machines, consuming electricity on a regular and continuous basis. Therefore, industrial UPS is very commonly used in this field, to help store electricity and maintain the operation of machinery and equipment without interruption or failure.
+ Application in daily life: UPS is widely used in daily life, ensuring the demand for electricity for electrical equipment such as lights, refrigerators or elevators on a regular basis. Uninterrupted. Therefore, shopping for yourself a UPS for the family is a legitimate need. The UPS used in daily life usually has a small capacity, compact size, and convenience.
+ Application in medicine – hospital: In medicine, the UPS plays an important role. It is applied in mechanical equipment such as ultrasound analysis, testing, X-ray … to help maintain operation, timely save images and data of patients easily and conveniently. . Ventilators, pacemakers, etc. should also be connected, using UPS to ensure optimal and safe patient service.
+ Application in traffic: Lighting systems, traffic camera systems, traffic lights also need to be continuously powered to ensure normal and safe traffic activities for road users. traffic on the street.
+ Applications in banking: Banks often use UPS to backup computer systems, ATM systems to ensure normal transactions, avoid confusion, data loss or unfortunate incidents. increase customer satisfaction and trust in the bank.
