(1) The input of the DC charger is a three-phase alternating current with a rated line voltage of 380V±10% and 50±1Hz;
(2) For AC chargers with a capacity of less than (or equal to) 5kW, the input is single-phase alternating current with a rated voltage of 220V±10% and 50±1Hz;
(3) For AC chargers with a capacity greater than 5kW, the input is three-phase alternating current with a rated line voltage of 380V±10% and 50±1Hz.
