控制變壓器BK系列 Control transformer

     適用於50-60Hz的交流電路中，廣泛用於電子工業或工礦、機床和機械設備中一般電器的控制電源，安全照明指示燈的電源之用。
     初次級繞組分開繞制，當次級隻有一個繞組時，它擔負變壓器的全部額定容量，註意事項:當次級如兼有控制，照明及指示燈繞組時，則按各繞組具有中間抽頭的變壓器，其各中間抽頭容量，皆小於變壓器的額定容量，隻有最高電壓輸出端可擔負額定容量。

     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
the capacity.

使用環境   Usage environment

1、周圍空氣溫度-50℃至+40℃，24小時的平均值不超過+35℃；
2、安裝地點海拔不超過2000m；
3、大氣相對溫度在周圍空氣溫度為+40℃時不超過50%，在較低溫度下可以有較高的相對濕度，最濕月的平均最大濕度為90 %，同時該月的月平均最低溫度為+25℃，並考慮到因溫度變化發生在產品表麵的凝露。

1、surroundings air temperature-50℃ to +40℃ an average value for ,24hours not exceeds+35℃;
2、install the location elevation not over 2000 m;
3、opposite degre of humidity in atmosphere at  surroundings air temperature is +40℃  hour not over 50%,under the lower temperature can have than High and opposite degree of humidity, the biggest degree of humidity  in the most  wet lumar average is 90%,at  the same time should average and lowest temperature in lunar month is+25℃ ,combine in consideration of  because of temperature the variety takes place in the superficial of water in product.
