The primarily pulsed power pack has been designed for field bus applications which transmit power and data via one single two-wire cable (AS-Interface concept). It supplies a fully extended AS-Interface system with a 8 A output current. Sinusoidal current drain from the mains avoids harmonics. The power factor correction feature ensures that the current and the voltage are almost cophasal to avoid reactive power and provide a cos φ > 0.6 power factor. The power pack makes available electric power. In addition to this, it provides for data isolation towards the power source and balancing of the two output lines (AS-Interface + and AS-Interface -) towards the reference potential of the machine (shield connection). Precise transformer coupling allows the use of unshielded load lines. Fuses: The power pack is electronically protected against external short circuits. In case of fault, the internal fusible link separates the power pack from the mains.
