Power inverter power selection of nine factors

by:Fangpusun     2020-05-19
First, to estimate the power of inverter power supply power according to the power capacity of the computer and its peripheral equipment, calculate the equipment of the total electricity consumption. Total power consumption multiplied by the factor of safety, is the power to estimate the power of inverter power supply, safety coefficient is typically take 1. 2 - 1. It is advisable to 3. Second, the choice of domestic and imported power inverter power supply in the domestic and imported power inverter power supply, the choice of general advice to choose domestic power inverter power supply. In recent years, domestic small power inverter power supply in terms of quality are greatly improved. Chosen for small power inverter power supply, on the one hand, is the support of the country's economic and technological development, on the other hand, there is much convenient in maintenance, such as relatively complete spare parts, maintenance capability and repair rate is satisfied. To import power inverter power supply general quality is better, but because of technical maintenance and spare parts is difficult, in the event of failure, often not timely repair, long-stalled cannot use. Domestic power inverter power supply in terms of job performance, is more conform to the domestic power supply situation, such as certain types of U, power inverter power input voltage range is wide, have stabilized output function, to adapt to the environment in our country some poor power supply condition. Sources of the people's bank of the electronic engineering construction, put forward the policy of domestic electric power inverter power supply, is undoubtedly opened a good start. Third, online and reserve power inverter power options to choose on-line or backup power inverter power supply, should according to the needs of computer equipment and economic condition. If economic conditions good optional on-line power inverter power supply; If the economic condition is poor, but does not affect the normal operation of microcomputer, backup power inverter power can also be selected. Fourth, short time and long time the choice of the power supply power inverter power supply in power supply power inverter power supply for a long time and short time on the choice of power supply power inverter power supply, basically be to see the needs of economic conditions and use. Economic condition is good, can choose power inverter power supply for a long period of time, or you can choose a short time power inverter power supply with small generating set as a standby power supply. 5 and understand the power of the inverter power supply using electric power state before the selection of power inverter power supply, to understand the power of inverter power supply used in power supply state. General electric power inverter power supply to the mains input requirement is: the input voltage to 38 ov + 10%, to 220 v + 10%; Frequency of 50 + 0. 5Hz。 If use field power supply is lower than the standard should be wide input range of the power inverter power supply, can also be in power inverter power supply front or add buy regulated power supply voltage regulation device. Sixth, choose a backup type power inverter power supply problems that should be paid attention to when choosing back-up type power inverter power supply, should pay special attention to the power supply switch time. Switching time, and the main reaction in computer power inverter power supply switch time and claim to the switching time. If choose undeserved, also can cause the microcomputer downtime when mains power failure, not the role of apc power inverter power supply. Seventh, to 'shop around' and select the current, small power inverter power supply of a lot of production and sales of manufacturers, product quality good beauty is not neat, price difference is big, therefore, should be more consultation, investigation, technical indexes and performance of different products to carefully compare prices; Select 'shop around'. Eighth, chooses import power inverter power supply some problems that should be paid attention to import power inverter power supply input and output connection mode is different from our country, should be paid attention to when choose the improvement method. The power inverter power supply, such as danger ( 脉冲) , powerware ( EXIDE) Models such as power inverter power supply input and output connection mode and the standard instead. In simple terms, the single-phase power supply is left zero right fire, while the United States is left fire right zero. In addition, but also notice the beautiful mark the style of the plug and socket are not the same as in China. National standard plug socket in the United States to China's national standard plug sockets, should pay attention to internal joint relationship, can't simply line. 9, maintenance convenience and selection factors when power inverter power failure is a normal phenomenon, in the selection, maintenance convenience, also is not to be sneezed at factors, otherwise it will bring inconvenience to use in the repair.
