Packing Quantity PCs 50 - 100 - 500 This SEPA high-tech miniature fan is suitable for industrial or automotive use and has a remarkable air flow performance despite its small dimensions. Due to a nearly linear air performance characteristic, the fan is applicable for different uses. It is permanently protected electrically against reverse polarity, block- ing and thermal overloading (by IC). Due to the low rotor weight and precision balancing, it is virtually vi- bration-free. It is also insensitive to shock. Further features of this fan are its extremely robust and torsionally rigid plastic housing of PBT (UL E54695), ball bearings with narrow tolerances, of special steel, polyester-based PCB (UL E44247) and absolute reliability due to 100% burn-in.

An alarm-board is available on request. The pulse is like a rectangular wave. The pulse frequency correlates to 2 x rotor speed, OC-output, a pull- up-resistor is needed. At blocked rotor the output signal could be L (0.5V) or H (Vcc). IMPORTANT: The pulse output is not protected against short circuit and must not connect to GND or Vcc without series-resistor. Do not connect not used pulse output to GND or Vcc (insolate). FAN OUTPUT WAVEFORM ALARM CIRCUIT MFB40H12xA red + + yel (Vce<15V, Ic<5mA) T blk 1n - - Run: L=0.5Vmax H=Vcc T =7.5msec, T =4.9msec, Stop=H/L (12LA) (12A) ACCESSORIES: ALG01 SEPA ALARM, monitor-circuit, generates an acoustic signal in case of missing pulses.
