AC/DC power supply / for AS-interfaces
PEPPERL & FUCHS
Data is transferred in an AS-Interface network and power is supplied along the same cable. A 30 V direct current is used as the power supply. Modulated onto this direct current as a data carrier is an alternating current. In order to supply power to each AS-Interface network, a special power supply with decoupling network is required.
A comprehensive range of power supplies for a wide variety of applications is offered by Pepperl+Fuchs. These all meet PELV requirements. A conductor for the AS-Interface is not necessary. In order to improve system safety, an additional ground fault monitoring function is integrated in some power supplies.
