-
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. 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. Model and its meaning (BK/DK) control transformer)
Working environment (BK/DK) control transformer)1.Ambient air temperature: -5¡æ~+40¡æ, the highest monthly mean temperature should not exceed +30¡æ;
2.Altitude for installing place should not exceed 1000m;
3.When the ambient air temperature is +40¡æ, 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¡æ, and condensation on the product surface caused by temperature change should be taken into consideration.
