　　1. Fan Test Method:

　　1.1 Current: Current measurement in continuous rotation after 3 minutes

　　1.2 speed: speed measurement in continuous rotation after 3 minutes

　　1.3 Starting voltage: After opening the switch "ON", the operation of the fan can be a starting voltage

　　1.4 Input Power: Input power measurement in continuous rotation after 3 minutes

　　1.5 Lock current: You can lock the machine fan, locking lock current measured three minutes in the fresh air

　　1.6 air flow rate data and pressure data measured according to "AMCA Standard" or DIN24163 rule, the data were measured in a double cabin pressure, and the need of each side of the cabin pressure was measured pressure data

　　1.7 Noise Standards: DIN45635 standard reference noise standard test, measurement soundproof room, the microphone is placed at one meter fan cooling fan

　　2. Fan protection test:

　　2.1 twist lock protection

　　2.1.1 fixed several fan blades together to limit the rotation, if the fan and electronic components are not damaged, limiting rotation loosen the fan assembly is automatically restarted rotation.

　　2.1.2 small current or fan belt Auto start function in power-rotating fan blades locked state, for 72 hours after the release is locked blades, fan immediately and automatically re-route to prove the fan without exception.

　　2.1.3 large current or fan without Auto start function, not long locks, otherwise the fan will overheat damage.

　　2.2 polarity protection

　　Under normal conditions, the voltage, reverse polarity power supply if the fan power for 15 minutes, power off again after the normal two poles connected, all functions will be normal

　　2.3 free fall

　　Monomer fell by 600mm height 30mm thick planks on the fan 6 surfaces either side and both corner withstand drop test, and confirmed that no damage.

　　2.4. Insulation resistance

　　Under the conditions of 500V DC, frame and wire cathode resistor less than 10MΩ

　　2.5. Dielectric strength

　　In 5mA leakage current, AC500V conditions for 60 seconds, the fan frame with wire without exception, prove good insulation
