AS-Interface systems require a 29,5V to 31,6V DC power supply conforming to IEC directives
(PELV : Protected Extra Low Voltage).
Each AS-Interface branch requires its own power supply.
The data filter integrated into the power supply constitutes the basic difference in comparison with usual
industrial power supplies. It enables the transmission of both power and data.
