Product Data Sheet 6314/2NPU 3.3 Electrical Interface - Output Tacho type Features Tacho operating voltage Tacho signal Low Tacho signal High Maximum sink current External resistor Tacho frequency Tacho isolated from motor Slew rate /2 (open collector) Note UBS US low US high Isink Values <= 32,0 V I sink: 2 mA <= 0,4 V I source: 0 mA <=32,0 V <= 20 mA External resistor Ra from UBS to US required. All voltages measured to GND. (2 x n) / 60 No => 0,5 V/us n = revolutions per minute (1/min) 3.
Product Data Sheet 6314/2NPU Internal Fuse: Littlefuse NANO2(R) FUSE; Very fast acting 451 Series; 4 A Note: The internal electrolytic capacitor 470uF/35V has no resistor or inrush current limitation, essentially the power supply and the type and length of the connecting cable is limiting the Inrush current.
