SOROTEC UPS

The output end of the early  solar energy inverter  system generally installed isolation transformer, to realize voltage adjustment and electrical isolation, to ensure safe and reliable operation of the system. However, isolation transformer of large volume, high cost, high loss, affect the system efficiency. If the use of high-frequency transformer to achieve the electrical isolation of PV and grid, which can reduce the system volume, quality and cost, but will not significantly improve the efficiency of the system. Therefore, non isolated grid connected photovoltaic inverter system has become a hot research topic. It has the advantages of high efficiency, small size, light weight, low cost and so on. But the elimination of transformers build electrical connection between PV and grid, leakage current could be increased substantially, conducting radiated interference, increase the net current harmonics and loss, even to endanger the equipment and personnel. Therefore, the co...

There are many performance parameters and technical conditions of the  solar powered inverter , here only a brief description of them. 1.Environmental conditions: altitude is not more than 1000m, air temperature of 0 ~ +40 ℃. 2.DC input voltage fluctuation range: ±15% of battery rated voltage. 3.Rated output voltage. In the specified input power supply conditions, when output the rated current, the rated voltage should be output by the  solar energy inverter . Voltage fluctuation range: single phase 220V ± 5%, three-phase 380 ± 5%. 4.Rated output current. In the specified output frequency and load power factor, the rated current value should be output by the inverter. 5.Rated output frequency. Under specified conditions, the rated output frequency of fixed frequency inverter is 50Hz, the frequency range of 50Hz ± 2%. 6.The maximum harmonic content of the solar inverter. Under the resistive load, the maximum harmonic content of output voltage should be less than or equal to 10%...

China has abundant solar energy resources, if wel make full use of them, can not only save a lot of conventional energy, but also can fully use of solar heating in some areas. Solar photovoltaic power generation technology can be used for any electric field, from the spacecraft to the home power supply. With the development of photovoltaic technology, gradually expand the application of photovoltaic power generation, solar photovoltaic products is mainly used for three aspects so far: one is for electric power supply; solar daily electronic products, such as various solar charger, solar street lighting, and so on; grid connected power generation, which has large area popularization and implementation in developed countries. Home solar power system  is becoming more and more mature and widely used. Germany’s million solar roofs plan makes many families use of solar photovoltaic power generation to resolve the problem of their own power supply and the family also accomplishing p...

The difficulties in the development of the  modular uninterruptible power supply  are mainly in the increase of the power density, the increase in the number of parallel, and the reduction of the price. Rack mounted modular UPS developed from the traditional vertical (tower type) structure, has wide cooling channel and a vast volume and high power cooling fan compared with the traditional vertical (tower type) structure, modular UPS is smaller and lighter to facilitate the replacement of the monomer. Due to the limit of the size, in the case of UPS module power increased, the heat dissipation has become a big problem. In order to achieve the purpose of safe work,  modular UPS syetem  not only uses the original passive heat dissipation, active cooling, axial flow and air duct diversion type cooling technology, but also uses the heat pipe cooling. In order to ensure the maximum availability and scalability of the power supply, the modules should be used in paralle...

With the size of  power cabinet , and then check the appearance of equipment, ensure matching wtih the selected support. A rugged cabinet can bearing weighing up to 450 pounds, so it is necessary to check the tools that handling equipment, such as lifting or trolley. The  power distribution cabinet   on wheels, so you only need to put the equipment installed in the cabinet, pushed to the right place. Measure the size of the room and the height of the ceiling, doors and lift to make sure that the cabinet can be passed. In addition, consider to the many types of equipment in the cabinet, to ensure that the cabinet is near the power, network cable spigot and communication socket. Check the angle of cabinet door open and closed. Standard cabinet door open on the right and the hinge on the left, of course, does not rule out the opposite situation. All the doors and side panels should be easy to open, easy to maintain. When you want to install equipment cabinet into an existing...

1.Battery low voltage protection: the battery will stop the power supply after discharge to a certain extent, to prevent the battery from permanent damage cause to excessive discharge. 2.Input overvoltage protection: precise control technology, cut off the AC input and continue uninterrupted for electrical equipment provided in compliance with the requirements of the power when the input voltage is too high or too low, prevent city electrical voltage is too low or too high to damage the device. 3.Output high voltage protection: when output voltage is too high due to sudden or unexpected events, the  rackmountable UPS  will alarm, city electric switch to bypass, cut off output if there is no electricity, so as to protect the UPS and electrical equipment. 4.Overload protection: the series of HP9115CRT  rack mount UPS power supply  collect load conditions in real-time, take different ways of protection for different degrees of overload, UPS can work in less than 12...

One kind is power  modular type UPS . Power modular Rackmount UPS is composed of a rackmount and power module, the power module including traditional UPS rectifier, filter, charging, inverter and so on. But the static bypass and the part of the system monitor and display the same rackmount. Each module is independently controlled in parallel operation, and the display control module on the upper part of the cabinet is only used as a platform to switch the UPS host and network monitoring by the user. The rackmount  modular uninterruptible power supply  is composed of rackmount and single module composition, each module is equipped with the UPS and the control circuit, including rectifier, inverter, static bypass switch and auxiliary control circuit, CPU main control panel. Each UPS module has an independent management system. Relative to electronic technology and components development, two kinds of structure have their own advantages, also have very good representative pr...
