BK series control transformerDetailed product description：

1. Purpose
The BK series machine tool control transformer (hereinafter referred to as the transformer) is suitable for circuits with voltages ranging from 50-60Hz to 500V, and is usually used as a power source for machine tool control appliances or local lighting and indicator lights.

2、 Structural features
BK transformers can be divided into shell type according to their structure and vertical type according to their installation method.

3、 Model and its meaning


4、 Usage environment
1. The ambient air temperature ranges from -5 ℃ to+40 ℃, with an average of no more than+35 ℃ over 24 hours;
2. The installation location shall not exceed an altitude of 2000m;
3. When the ambient air temperature is+40 ℃, the relative humidity of the atmosphere does not exceed 50%. At lower temperatures, there can be higher relative temperatures. The average maximum humidity in the wettest month is 90%, and the average minimum temperature in that month is+25 ℃, taking into account the condensation that occurs on the surface of the product due to temperature changes.
