What is the power of transformation?

In voltage conversion, power refers to the maximum power that can be output from a transformer, which is the product of its current and voltage when the transformer is in stable operation. This power value is usually expressed in units of VA (watt-amperes).
Specifically, power is the product of voltage and current, i.e., P = V x I, where P represents power, V represents voltage, and I represents current. This power indicator reflects the size of the transformer capacity.
It should be noted that the input power and output power of a transformer should be as close as possible to minimise power losses. In addition, the power of a transformer is limited by its core volume, coil weight and transformer weight, which is a fixed value. Therefore, the power of the load should not be greater than the power of the transformer.
When selecting and using a transformer, it is very important to know its power, as this determines the power demand that the transformer can fulfil. If the power required by the equipment exceeds the power rating of the transformer, then the transformer may not work properly and may even be damaged. Therefore, when selecting a transformer, it is important to ensure that its power meets or exceeds the needs of the equipment.
