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.
