Product Details

1. Application (BK/DK) control 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.

2. Structure character (BK/DK) control transformer)

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

3. Working environment (BK/DK) control transformer)

1.Ambient air temperature: -5°C~+40°C, 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 by temperature change should be taken into consideration.
