Important Note :
Rated Current : Rated Current shall be measured after 3 minutes of
continuos rotation at rated voltage .
Rated Speed : Rated Speed shall be measured after 3 minutes of
continuos rotation at rated voltage
Start Voltage : The voltage which is able to start the fan to
operate by suddenly switching “ON”
Dropping test standard : Drop a minimum packing box in a height of
30 cm for perpendicular free falling motion to the surface of
wooden plate of 10 cm . After test , connect the fan to the power ,
the fan still in normal operation .
