BK transformer

BK series machine tool control transformer is suitable for circuit of 50~60Hz, voltage up

to 500V, usually applied as power supply for machine tool electrical appliances, local

lightings and indicator lamps.

According  to different structures,  BK  transformer belongs to shell type,  and according

to the  installation mode, it belongs to vertical type.

1.Ambient air temperature: -5℃~+40℃, the highest monthly mean temperature should

not exceed +30℃;

2.Altitude for installing place should not exceed 1000m;

3.When the ambient  air  temperature is +40℃, the relative humidity should  not exceed

50%, and  it allows  higher relative humidity under lower temperature. Max average

humidity in the  dampest month is 90%,  meanwhile  the lowest average temperature

of  this  month is  + 25℃,  and  condensation  on  the product  surface caused by

temperature change should be taken into consideration.

JMB

It is suitable for AC circuit of 50~60Hz, widely applied in electronic industry, industrial and

mining enterprise, worked as control power supply  for usual circuit of  machine tool and

mechanical  equipment and as power supply for safety lighting and indicator lamp.

The primary and secondary windings  are winded separately, when the secondary  one

only has one winding, then it takes on all the rated capacity for transformer. If the seco

-ndary one accompanied with control, lighting and indicator lamp windings, it will be

winded respectively according to each  winding  capacity.  For  simplex winding tra

-nsformer with center tap, all the center taps capacity should be lower than rated cap

-acity of transformer, only the max voltage output terminal can bear the rated capacity.

The transformer can work reliably under the following conditions

1.Altitude should not exceed 2,500m;

2.Ambient air temperature: -25℃~+ 40℃;

3.Relative humidity: max average relative humidity of the dampestmonth is 90%;

4.Places that are free from severe vibration or shock;

5.Environment exists without explosive medium, gas or conductive dust hat will erode metal

and destroy  insulation;

6.Places that are free from rain or snow.
