Product Description

BK transformer comprehensive used in AC 50-60HZ, where input, output voltage not over than 660V. BK series 12v to 220v transformer is commonly used in machine tool working as local lighting, power of indicator light or the machine control electric appliance
 

1. Ambient air temperature: -5 degree ~+45 degree, the highest monthly mean temperature should not exceed +30°C;

2. Altitude for installing place should not exceed 2000m;

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.
