In the traditional X2 safety capacitors, the general labeling is 275V, but now some manufacturers' X2 safety capacitors have become the highest 310V, which makes many people confused, X2 safety capacitors 275V and 310V are the same? ? What is the difference when using it?
The meaning of this voltage is:
275V~ represents the rated voltage of 275VAC;
310V~ represents the rated voltage of 310VAC;
In fact, there is no difference between the two: the safety X2 capacitor 275V and 310V are common, the price and the size of the product box are no different. The 310V contains 275V, and manufacturers have gradually used 310V printing.
In fact, the rated voltage of X2 safety capacitors is generally: 275V / 305V / 310V, they are actually universal.
This situation is mainly caused by different rated voltages in different countries and different safety certification requirements.
A small reminder: the safety certification of different countries, the rated voltage requirements of X2 capacitors are not the same.
The rated voltage required for CQC certification is 310VAC, and other countries require: 275V, 305VAC 310VAC.
