The BK series control transformers are suitable for circuits with frequencies of 50-60Hz and voltages up to 500V. They are typically used as power sources for local lighting and indicators of control electrical appliances in machine tools. This type of transformer can be classified into shell type by structure and vertical type by installation method.
Usage environment
Ambient air temperature: -5℃ to +40℃, with a 24-hour average not exceeding +35℃;
Installation altitude: not exceeding 2000m;
Atmospheric relative humidity: not exceeding 50% when the ambient air temperature is +40℃. At lower temperatures, higher relative humidity is allowed. The average maximum monthly humidity in the wettest month is 90%, and the average minimum temperature in that month is +25℃. Condensation on the product surface due to temperature changes is also taken into account.
