(1) "Micro Cooling Fan" direct parallel connection of the power supply is properly connected with a variety of load power supply applications is an important part. Figure 9-21 is a power supply wiring methods with several loads connected in parallel. The figure, the voltage and the load voltage of each other on the load size and power ground related. If the load current is large, the pressure drop in the transmission lines will increase, so far away from the power supply output voltage is below standard load and load changes will cause deterioration of the stability of the output voltage. "Micro Cooling Fan" in addition to the load current is very small, the line voltage drop can be ignored, but this connection can not be used.
(2) "Micro Cooling Fan" radial connection gives a radial connection method, which is a good connection. Thick wire with a pair of power leads, respectively, for each load at the same point relative to connect to it, basically there is no problem of interaction between the various loads.
