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.
