(3) "220V Cooling Fan" To leave a margin so-called margin actually derating. Modern electronic systems, digital circuits account for a large share of the digital circuit voltage and current waveforms are pulses, although the average power is not great, but the value of the instantaneous power is very impressive, no power supply margin is likely to make the whole electronic system crashes.
(4) "220V Cooling Fan" as far as possible according to the functions of distributed solutions based on electronic systems in a variety of features designed regulator circuit, respectively. For example, digital circuits, analog circuits, high-power output circuit power supply, respectively the way to be taken to minimize the interaction between these power supplies.
(5) "220V Cooling Fan" to minimize the distance from the load between the power supply and the power load between shorter, one can reduce the cost of the power system, on the other hand can enhance immunity and reliability of the power system.
