Definition of AC input: 

Allocation of neutral line: For power supplies with power factor 0.4~0.6, when several sets of power supplies used in 3-phase, 4-line input system, the current of the neutral line cannot be offset because of the distortion of the input current wave. Therefore, in normal circumstances, we suggest that the neutral line should be allocated as 1.5~2 times the cross-sectional area of the hot line.  Leakage current: When several sets of power supplies connected to ground at the same place, the leakage current will be redoubled accordingly. Care must be taken to avoid electric shock. Battery charger: Most of our single output power supplies above 100W can be directly used as battery charger by means of floating charge (constant current limiting).

    Four typical ways of series-parallel connection as follows:
