How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...

126th Canton Fair

On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

Requirements of inverter for physical environment

图片
Due to the high integration, compact overall structure and large heat dissipation, the  hybrid inverter  requires high temperature, humidity and dust content in the installation environment. When installing the  solar inverter , it must provide a good operating environment for the  inverter . The working ambient temperature of the inverter is rated at 40 ℃. If the ambient temperature is higher than 40 ℃ ~ 50 ℃, the rated current must be reduced. Otherwise, the temperature rise of the device will be too high, which will increase the possibility of device damage (especially IGBT power module), and have a great impact on normal and safe operation. If the working environment of the inverter fails to meet the requirements of the inverter on the working environment, it will cause high failure rate of the inverter, affect the long-term, reliable and safe operation, resulting in unnecessary economic losses. Therefore, the following matters should be paid attention to in the...

It’s a great honor for soled to participate in the power security system of the games. SOROTEC  GP9335C series online UPS provides power support for Wuhuan sports center. During the military games,  SOROTEC  sent many engineers to the venue all day, recording the ups operation status in detail, ensuring that the power supply system is uninterrupted for 24 hours, providing stab...

Matching between Generator Set and UPS

图片
Manufacturers and users of  UPS power supply system  have long noticed the matching problem between generators and UPS, especially the harmful effects of current harmonics generated by rectifiers on  power supply systems  such as voltage regulators of generators and synchronous circuits of UPS. Therefore, the technicians designed the input filter and applied it to UPS, and successfully controlled the current harmonics in UPS application. These filters play a key role in UPS compatibility with generators. In fact, all input filters use capacitors and inductors to absorb the destructive current harmonics at the UPS input. The design of the input filter takes into account the percentage of all possible harmonic distortion inherent in the UPS circuit and at full load. Another benefit of most filters is to increase the input power factor of UPS with load. However, another consequence of the application of input filters is to reduce the overall efficiency of UPS. Most...

Power Supply Requirements of 5G power system for 5G Communication Base Station

图片
Chinese traditional industries are becoming increasingly mobile and data-based, and domestic information construction will be in a high growth trend for a long time. In this context, UPS as a power supply infrastructure will be more and more used in emerging industries, especially 5G power system , new energy, transportation, electricity, health and other industries will become a new demand growth point. In the process of modernization, intellectualization and convenience of communication, finance, medical treatment, education, scientific research, manufacturing and other industries, all kinds of global top-notch equipment and systems appear centrally.  5G power supply will inevitably become the supporter of high-end equipment, providing stable power supply for high-end equipment and intelligent information system. With the end of the 5G power supply standard (R15), the commercial use of 5G network devices and the release of 5G mobile phones, 5G has become one of the hot top...

Trip to Phoenix Mountain

Summer is coming, everywhere is full of vitality, after the Dragon Boat Festival, it is obviously hot up.Taking advantage of the cool weather, Colleagues from sales department decided to set out for Phoenix mountain. Colleagues left the busy work, went to the nature to breathe the fresh air and do exercise .We closed to nature and felt its vitality, also for our new friends to join thesales department . To promote mutual understanding and communication, Strengthen our team spi rit, build and foster a sense of cooperation , our “phoenix mountain brigades” began! Start climbing!Everyone in good spirits and high spirits, striving towards the top of the mountain.Although some partners due to physical reasons to slow down the pace of climbing, but they encourage each other, mutual support, everywhere reflects the strength of unity.After about one and a half hours, all reach the peak. The mountain wind blew dry our sweat, we looked around, really have a list of small mountains fe...
