The working principle of telecom inverter

Telecom inverter is a kind of device which alternate 220V power frequency current into the voltage regulator output DC voltage, need to go through transformer, rectifier, filter, voltage regulator four links to complete. Each link has its role, the following is a small series of its summary.
1.The rectifier filter circuit: rectifier circuit to AC voltage UI is converted into DC voltage ripple, ripple through the filter circuit to filter components and large DC voltage U1 rectifier and filter circuit, the output ripple is less commonly used full wave rectifier filter, bridge rectifier filter etc..
2.Power transformer: step-down transformer, 220V AC voltage converter with AC voltage to the power grid, and to the rectifier circuit, transformer secondary voltage of the transformer is determined by the secondary voltage.
3.Voltage regulator circuit: the function of the voltage regulator circuit is to make the output of the DC voltage stability, does not change with the AC power grid voltage and load changes. Commonly used integrated regulator has a fixed three terminal voltage regulator and adjustable three terminal voltage regulator.
4.Filter circuit: the rectifier circuit output voltage of the most of the AC components to be filtered, so as to get a smooth DC voltage, each filter capacitor C meets RL-C=3~5T/2 or T for input AC signal period, and RL is the equivalent load resistance of rectifier filter circuit.

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...

126th Canton Fair

图片
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

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...
