Power 2.5KW three-phase loads should choose which model specification regulator

1 Power: If your 2.5KW load is basically constant, there is no start-up characteristics (current), orders of magnitude larger can be (leave a margin), on the contrary, we should consider the power and margin at the time of start-up.

2 Voltage regulator precision and selection: understand the range of fluctuations in the current grid, the range of fluctuations in the load requirements, to determine the accuracy of the voltage regulator (some called precision), the rate of voltage adjustment, anti-interference and other requirements, to consider the structural form of the regulator (magnetic saturation, motor adjustment, electronic, etc.)
