一、適用范圍Sphere of application

   BK系列控制變壓器適用50~60HZ電壓至500V的電路中，通常用作機(jī)床和機(jī)床設(shè)備中一般電器的控制電源，或局部照明燈及指示燈的電源之用。

   BK series control transformer for 50~60Hz voltage to 500V circuits machine tools and mechanical equipment commonly used in the general control of electric power, or local lighting and power indicator light purposes.

二、使用環(huán)境Working condition

2、1周圍空氣溫度-5℃至+40℃，24小℃時(shí)的平均值不過+35%；

2、2安裝地點(diǎn)海拔不過2000m,

2、3大氣相對(duì)濕度在周圍空氣溫度為+40℃時(shí)不過50%，在較低溫度下可以有較高的相對(duì)濕度，濕月的平均相對(duì)濕度為90%，同時(shí)該月的平均溫度為+25℃，

2、1 The aient air temperature of -5℃to +40℃,24-hour average does not exceed+35℃；

2、2 Installation site altitude does not exceed 2000m;

2、3 The atmospheric relative humidity in the aient air temperature is +40℃less than 50%,

 at a lower temperature can have a higher relative humidity,the average maximum humidity of 90%,while the monthly average minimum monthly temperature to +25℃.

三、結(jié)構(gòu)特點(diǎn)Structure

   BK系列控制變壓器是經(jīng)過多年來進(jìn)一步國內(nèi)外同類產(chǎn)品的優(yōu)點(diǎn)，采用工藝和嚴(yán)謹(jǐn)設(shè)計(jì)進(jìn)行制造，并優(yōu)選國外方法的接線端子，具有性能優(yōu)良、工作、耗能低、體積小、接線、護(hù)等級(jí)高、適用性廣等特點(diǎn)。在額定負(fù)載下能長(zhǎng)期工作，是一種理想的變壓電源。

  BK series control transformer is the result of similar at home and abroad for many years to further absorb the advantages of using advanced manufacturing techniques design,and advanced optimization methods terminals,with excellent performance, reliable operation, low power consumption, all size,wiring security, protection levvel high, wide applicability and so on. Rated load in the long-term work is an ideal transformer power supply.
