Product Overview
The Siemens part 3RX9503-0BA00 is an AS-Interface power supply unit from Siemens' AS-Interface power supply family. It converts an AC input voltage of 120 V or a wide range of 230-500 V AC into a regulated 30 V DC supply (8 A) for AS-Interface networks. The unit includes integrated ground-fault and overload detection and data decoupling for AS-i, and carries an IP20 rating. It is used in industrial control systems to reliably power AS-Interface bus segments in distributed automation applications. 3RX9503-0BA00 plugs into DIN-rail environments and supports typical machine-level power distribution.
