24V DC Cooling Fan load

"24V DC Cooling Fan" should pay more attention. And the load wire is too long, these connections change the value of the loading effect of several milliohms contact resistance and there may be a few percentage points. Should remember some important reference value: a 5V output, "24V DC Cooling Fan" from no load to full load change has 5mV, the loading effect of 0.1%, a 12V output from no load to full load change has 2.4mV , the load effect is 0.02%. Clearly, high-current contacts should be properly addressed and welding. "24V DC Cooling Fan" spade lugs, banana plugs, etc. must be carefully rust treatment. Planar board should provide several parallel contacts for high current loads, and to ensure clean.
