一、适用范围 Sphere of application

        BKZ系列整流装置是由BK变压器和整流无件组合而成。变压器适用于在的边电压为220V或380V，交流50Hz的电源，输
出电压经晶体管整流元件整流器流元件整流后输出直流，用于蓄电池充电，以及将交流电源变成直流电源用在设备上。

      ZBK series rectifier is made up of BK transformer and rectifier cell.It is suitable for powerwith 220V or 380V,50Hz primary side voltage.The
output voltage will become direct current after the rectification of transistor rectification component and trans former rectification componentm,then
it is used in the charge of storage battery or in the equipment by changingalternation current into direct current.
