5:Sincere cooperation     BK(DK) Series 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   B:Transformer                     D: Single Phase   K: Control                            K: Control      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 1000m;
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.
