All dimensions, direction of rotation and air flow were specified as per drawing attached.
The blade is count Clockwise viewing from the blade. The same direction also indicated by an arrow mark on one side of the housing.
All fans have integrated protection against locked rotor condition so that there will be no damage to winding or any electronic component. Restarting is automatic as soon as any constraint component to rotation has been released. As fan placed at dead angle position, and the switch of FAN was changed from off to on,Restarting was automatic normal as soon as and proved that this fan is good fan
No damage shall be found with reverse connection 5 minute at rated voltage. After returning to normal polarity, all function shall be normal.
The product drops from the bight of 600mm to the wood board of 30mm. Any one of the 6 faces and any one of the corners could withstand the pressure, and also no damage will be found..ELECTRICAL INSPECTION
Not less than 10M ohm between housing and positive end of lead
wire(red) at 500V DC. No damage should at 500 VAC for 60 sec, measured with 5mA trip
current between housing and positive end of lead wire. The continuous duty life at given temperature after which,90% of testing units shall still be running.
7.0 ENVIRONMENTAL All function shall be normal after 500 hours storage at -40℃ to
+50℃ at normal humidity with a 24 hour recovery period at room
temperature. After 96 hours 95%RH 40+/-2℃per MiL-STD-202F, method 103B humidity test, the measured data on insulation resistance and dielectric strength shall meet the specification.8.0 REMARKS 8.0 REMARKS 8.1 Matetial and construction are subject to change without advance.
