河北秦皇岛BK-750VA 输入380V 输出AC230V接线端在一边控制变压器

控制变压器BK系列 Control transformer

     适用于50-60Hz的交流电路中，广泛用于电子工业或工矿、机床和机械设备中一般电器的控制电源，安全照明指示灯的电源之用。
     初次级绕组分开绕制，当次级只有一个绕组时，它担负变压器的全部额定容量，注意事项:当次级如兼有控制，照明及指示灯绕组时，则按各绕组具有中间抽头的变压器，其各中间抽头容量，皆小于变压器的额定容量，只有最高电压输出端可担负额定容量。

     Exchanges electric circuit inside that be applicable to 50-60Hzs,it is extensive is general with the machine equipments inside in electronics industry or work mineral,machine beds The control power supply of the electric appliances, the  safety illuminates the power  supply  of the designation light it use.
    The first time class rounds an all sums for separating to round the system, being the time class only reaching first rounds set,it carry the transformer settles the capacaity,time The class presses if there is control, illuminate and instructions linght rounding concurrently set,esch round a capacity allotment round the system, to single round set and have the middle take out A sum for of transformer,its eachly in the center take out a capacity,all smaller transformer settles the capacity, only have the tallest electric voltage output to carry can load The negative sum settles
