| Abstract: | HMSC-2000-17A automatic hermetically sealed lead-acid accumulator charge is external accumulator charger of line administrative units (LAUs) in 408UL Tele-seismograph. The key elements of the charger uses advanced DC/DC transform module having zero-current switch produced by American Vicor Company. It is difficult to know the working principle of charger and carry out maintenance of charge for users because contractors do not provide circuits. We plotted circuits according the material objects and expounded working principle of charger. |
