4184N/2XH

4114 N/2XH 4184 N/2XH DC Axial Fan DC Axial Fan 38mm flat axial fan for DC operation with very high power/performance. Driven by an electronically commutated external rotor motor. Electronic commutation system is integrated into the motor hub. Air flow and noise level can be controlled by varying the supply voltage range. Features • Electronically protected against blocking and overloading. • Electronical protection against reverse polarity. • Extremely low EMI. • Electrical connection 4114 N/2XH: via leads 4184 N/2XH: via 2 flat pins 2,8 x 0,5 mm and extra tacho lead General Data Nominal voltage V DC 24 Voltage range V DC 12...25 Nominal speed -1 min 4400 Max. flow rate m3/h 237 Max. flow rate CFM 139,5 Noise free air dB(A) 59 bels 6,5 Current consumption mA 460 Power consumption W 11 Perm. ambient temperature °C -30 ... +55 Service life (55 °C) h 52 500 Service life (40 °C) h 70 000 Noise in optimum operating range at max. voltage Patents granted or applied for.
