Product Description

This DC fan material is high quality and special (for example, it has copper inside leaves,  so it works very stable and slience...), and it has a brain---programme chip on PCB, controls DC fan's work: the air flow will be bigger and bigger when temperature increases, 
and when it cooler, the speed will slow down --- this way to protect machine and save 
energy.

DC diagonal compact fan (sickled blades)

      

Technical features    

      

Dimensions172Ø x 51 mm  

General descriptionDiagonal fan with low noise when there is a high pressure

  saddle curve. Very rigid compression curve for high

  counterpressure. Electronic commutation completely

  integrated.  

CharacteristicsElectronic commutation external engine with blocking

  protection and wrong pole protection.

  Air achievement within the permissible voltage range

  adjustably.   

  Overload protection restart after 3 seconds.

  Alarm exit / Open Collector / low aktiv

  Direction of rotation reversal (N.C or <0,8 V normal,

  5V 50V Revers)  

  Coil and electronics fully recast. 

Connection lineSingle strands AWG 22, TR 64, bared and tin-plated.

  Cable length: 4.500 mm +/-10 mm

Alarm exit V max   40VDC  

  I max     20mA    low >=0,4V at 2mA

Alarm informationsThe alarm exit becomes active (with a delay of some

  seconds), if the exhaust turns more slowly than 75%

  of the target number of revolutions given at the

  control inlet.  

Direction of protection Left, looking at rotor  

Direction of air flowAir exhaust over bars  

Bearing Ball bearings  

Lifetime L10 at 40°C65000 h   

Weight/Mass0,820 kg   

Housing materialAluminium. Housing with grounding lug for screw

  M4 x 8 (TORX). 48 V version including screws.
