1. Swivel lock protection 1.1 several fan blades are connected together to restrict the rotation. If the fan and electronic components are not damaged and the components that restrict the rotation are loosened, the fan can automatically restart the rotation. 1.2 the fan with small current or with Auto start function, lock the fan blade in the power-on rotation state, and after 72 hours, release the locked fan blade, and the fan will automatically restart immediately, proving that the fan is normal. 1.3 fans with high current or without Auto start function, do not lock for a long time, otherwise the fan will be overheated and damaged. 2. Polarity protection Voltage
DC FanWhat are the protection tests? Here is a brief introduction:
1.swivel lock protection
1.1Several fan blades are connected together to limit the rotation of the fan. If the fan and electronic components are not damaged and the components that limit the rotation are loosened, the fan can automatically restart the rotation.
1.2Small current or bandAuto startFor the fan with function, lock the fan blade in the power-on rotation state, and continue72After hours, release the locked fan blade, the fan will automatically restart immediately, proving that the fan is normal.
1.3High current orAuto startThe functional fan cannot be locked for a long time, otherwise the fan will be overheated and damaged.
2. Polarity protection
Under normal voltage conditions, if the reverse power supply energizes the fan15Minutes, press the normal two-pole connection again after the power is off, all functions will be normal
3.Free fall
monomer600mmFalling from high altitude30mmon a thick board,Fan6Any one of the surfaces and a corner can withstand the drop test.,Make sure that there is no damage.
4.Insulation impedance
In500VUnder DC condition, the positive resistance of outer frame and lead shall not be less10MΩ
5.Insulation strength
In5mAleakage current,AC500Vsustained under conditions60seconds, the fan frame and the wire are not abnormal, which proves that the insulation is good.
