Automotive datasheet 8412 EN

customized design!
8412ENHV / 17-175
DC axial fan
– Low noise level by special commutation electronics
– Electronic locked rotor and reverse polarity protection
– Self-diagnosis function: In case of failure (stiffness/blocking) a signal for speed control
will be pulled down to ground. Loss of electrical contact will cause shutdown of motor
– External speed setting via PWM
– Speed control and diagnosis combined in one wire
– Closed loop speed control (restricted, working independently of nominal operating
voltage and charge)
– EMC protective measures suitable for direct connection to vehicle supply system
– Flanges for application in sucking or blowing operation
– Housing made of 2 parts to facilitate assembly and to avoid mechanical stresses
to the bearing system
