The DYS152-050200W-K is a general purpose AC/DC Adapter converts 100 to 240VAC to a stabilized DC voltage of 5V with rated output current of 2000mA. The minimum efficiency shall be 73.37% under 115/230VAC input and output full load. The switching mode power supply shall be able to start up into a resistive load up to the maximum rated current with maximum load capacitance of 1000?F. The elapsed time between the application of input power and the attainment of output voltage to the nominal value shall not exceed 3 seconds. The switching mode power supply shall withstand a continuous over current without damage. It may be applied before powerup or after power-up. The switching mode power supply shall perform normally again after the over current is removed.
