Usually the power distribution voltage is not 220V, 380V, the low three-phase power is more than 200 volts, the high one is 400 volts, and the single-phase power is the same. The high and low voltages sometimes differ greatly, so before we buy the voltage stabilizer, we need to have a measurement on the electrical sample used.

power supply

Switch mode power supplies are a constant power load. If you assume the output to draw a constant power ; for example 3.3V 1A. This equals to 3.3W which means whatever the input voltage is, it will always draw 3.3W. In practice you have efficiency (which can vary) and limits to the voltage region, but it will try to draw 3.3W.
