Single phase toroidal transformer BK-300VA control |

Single phase toroidal transformer BK-300VA control |

control transformer(Hereafter call transformer) is suitable for circuit of 50~60Hz, voltage up to 500V, usually applied as power supply for machine tool electrical appliances, locallightings and indicator lamps power supply.

Structure Character:

 According  to different structures,  BK  transformer belongs to shell type,  and according to the installation mode, it belongs to vertical type. 

Model Means:

  BK-x                                          DK-x

  x: Rated Capacity                  x: Rated Capacity

Working enviconment:

1.Ambient air temperature: -5 degree ~+45 degree , the highest monthly mean temperature should not exceed +30°C;
2.Altitude for installing place should not exceed 2000m;
3.When the ambient  air  temperature is +40°C, 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°C,  and  condensation  on  the  product  surface  caused  bytemperature change should be taken into consideration.
