"24V DC Cooling Fan" polarity protection
Under normal conditions, the voltage, reverse polarity power supply if the fan power for 15 minutes, power poles as normal after re-connect, all functions will be normal
"24V DC Cooling Fan" free fall
Monomers by 600mm height 30mm thick planks fell on the fan six surfaces were withstand any side and corner drop test, and confirmed no damage.
Insulation Resistance
Under the conditions of 500V DC, frame and wire cathode resistor less than 10MΩ
"24V DC Cooling Fan" dielectric strength
In 5mA leakage current, AC500V conditions for 60 seconds, the fan frame with the wire without exception, proved good insulation
