The solution for UPS unexpected jump to battery power supply mode

The city power is normal, people can surf the Internet, but UPS always jump to the battery power supply mode. And in this mode there is always a beep. We immediately organized the staff to check the circuit and analyze the cause of the failure. Finally it linked to the vertical air-conditioning room, every time start the air conditioning for a while, it automatically converted into battery powered. Obviously this is due to the impact of high power air conditioning to the city power output. But they are separated in two power supply, from the switchboard of different distribution room, how will interfere with each other?

With this question, the electrician followed the wire to open the ceiling, floor, junction boxes, etc.. in order to figure out that if there is a place where the circuit is falsely connected, and finally found that the zero line and the ground wire are connected together. So fuzzy interference can have an impact on the high frequency online UPS, it really is a precision device.

We decided to separate the ground wire of the air condition. After separating the zero line and the ground wire, and then start the air conditioning, found the UPS never jump again. So why this problem did not appear before? We believe that is the weather is too hot, air conditioning full load operation, which increased power consumption.

The quality of power supply is very important to the stability and security of the enterprise network. However, there are many properties of network power security, such as high performance, scalability, reliability, functionality, accuracy and availability, etc.. In order to make the enterprise network power supply can continue to run steadily, in addition to the usual use of norms, the periodic use of a variety of testing tools for the implementation of maintenance testing of the network environment is necessary. The entire room power supply safety system, need technical personnel to maintain seriously, and to do a good job of routine investigation, timely detect the problems, analysis of the impact caused by unplanned downtime.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

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 ...

How to maximize the efficiency of your UPS

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...
