Model and its meaning (BK/DK) control transformer)
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.
