UPS uninterruptible power supply is a kind of power protection equipment that can provide stable and pure AC power for important equipment when the mains is abnormal or interrupted. It is mainly composed of rectifier, inverter, battery, static switch and other parts, with no power, voltage purification, management and monitoring functions.

The role of UPS uninterruptible power supply is to ensure the normal operation of equipment and data security, to avoid power problems caused by equipment damage, data loss, business interruption and other losses. It is widely used in computer, communications, medical, industrial, aviation and other fields, is an important means of power security.

The advantages of UPS uninterruptible power supply are high efficiency and stability, comprehensive protection, intelligent management, and easy expansion. It can adapt to different power grid environments and load requirements, and provide high-quality power solutions for various equipment.
High efficiency and stability: double conversion circuit design is adopted to realize the voltage and frequency stabilization of input and output, improve the quality of power supply and protect the load to the maximum extent. It also uses dedicated integrated power IGBT to improve inverter efficiency, high output accuracy, save energy and reduce noise.

Comprehensive protection: with overvoltage, undervoltage, overcurrent, over temperature, short circuit and other multiple protection functions, can effectively prevent the damage of power supply and equipment. It also has a perfect alarm function, which can prompt the user the status and fault information of the power supply in time, which is convenient for the user to deal with it in time.

Intelligent management: the use of distributed monitoring system, can carry out comprehensive monitoring and control of each part, to achieve remote unmanned "four remote" monitoring, improve the safety and reliability of the power supply. It also has intelligent charge and discharge management and temperature compensation functions, which can automatically adjust the charging method to ensure accurate battery management and maintenance, extend battery life, and improve battery performance.

Easy to expand: it has good expansion performance, and can increase or decrease power modules or battery modules through parallel connection or hot plug according to the needs of users, so as to realize flexible configuration and expansion of power supply. It can also achieve full isolation of input and output to ensure stable, safe and reliable power at the output end.

1. Determine the required UPS capacity: First, list all the equipment that needs to be protected, and obtain its voltage and power data from the backplane of the equipment. The two are multiplied to obtain the voltammetric value (VA). Then, calculate the sum of all loads in watts (W). Next, the UPS capacity is calculated according to the power factor, impact resistance and expansion requirements of the UPS. It is recommended to increase the VA value by 30% as reserved expansion capacity for system upgrade.

2. Determine the required UPS type: According to the load's requirements for output stability, switching time and output waveform, select online, online interactive, backup, sine wave, square wave and other types of UPS. On-line UPS has good output stability and instantaneous response capability, is suitable for non-linear load and inductive load, has a high safety factor, and can resist a variety of violations on the power grid, such as high voltage, spike, surge and noise interference. For precision equipment, important equipment and high-end servers, online UPS is recommended. Avoid using interactive and backup UPS in areas with large fluctuations in mains power. If you need to use a generator with a short delay UPS, you recommend use an online UPS, because the voltage and frequency stability of ordinary generators are poor, which may cause the interactive and backup UPS to work abnormally.

3. Determine the required battery backup time: Determine the battery backup time according to the working time required by the device after power failure. It should be noted that the battery cost used by the long delay model may exceed the UPS host itself. Therefore, it is recommended to choose better quality batteries to improve the reliability of the UPS system.

4. Additional functions: In order to improve system reliability, it is recommended to use UPS hot backup system, which can be selected as series hot backup or parallel hot backup. For small capacity UPS(1 ~ 2KVA), redundant switches can also be used. In addition, remote monitoring panel can be selected to realize remote monitoring and control of UPS; monitoring software is selected to realize intelligent management between computer and UPS; network adapter is selected to realize network management based on SNMP; lightning protection device can be equipped in rainy and thundery areas.
