dc switching power supply

La description

With the rapid development of the electric power undertaking of our country and the investment in large-scale technical transformation, the requirement for DC switching power supply equipment and system is getting higher and higher. Shortcomings such as poor accuracy of voltage and current regulation, ligh coefficient of waves and the serious pollution of harmonic waves to the power grid exist with the past phased power supply and magnetic saturation power supply, which cannot meet the requirement for the development of our power works and all other industries. The JZ series intelligent high-frequency switching power supply system has the advantages of high accuracy of voltage and current regulation, high speed of response, small noise, high efficiency, etc. And can conveniently perform “*-remote” function and N*1 standby redundancies, so that the operation of the switching power supply is safer and more reliable. The nuclear parts of this series product are JZ-xxxxxx series high-frequency power supply module and JZ-MC-XX intelligent monitoring unit. The capacity of the system can be designed by combination according to the requirement of the user, and all special requirements of users can be met. Features of the system 1. Complete functions The two-loop AC connection unit can achieve the manual and automatic switching of two-loop AC power supply, and the AC two-loop power supply s can be chosen. The AC is converted into DC by the high-frequency power supply module, and this DC supplies power to both the load and the accumulator. The intelligent monitoring unit controls the whole system and performs the functions of trouble alarming, display, keyboard operation, battery charge management, long-distance communication, etc. The system integrates AC distribution, DC distribution and high-frequency power supply modules, intelligent grounding round inspection unit, intelligent rex_yf at xxxxx
