Voltage regulator selection method

When you want to select regulator,you should calculate th sum of ll load powers,to avoid over load,and when you calculate that,if they are freezer,refrigerators,you must remember to use power times finve,if they are air conditioning,air condtioners, you can use power  times 3,and to other inductive olad you can use power tmes 2, according to the calculation of the total power then to choose the appropriate size of the regulator.

If the voltage of mains voltage always less than 160V,you can multplied by 1.8 when calculating total power,so to insure it can also have excellent load characteristics during the voltage is low.
