PSN130S 4A 120V-230VAC IP20 Power supply unit 30V 3RX9512-0AA00

The PSN130S 30 V power supplies feed 30 V DC into the AS-Interface cable and supply the AS-Interface components, but do not include data decoupling. Additional data decoupling units are needed to separate communication signals and supply voltage, see “S22.5 Data Decoupling Modules” or “Data Decoupling Modules for S7?1200” → “DCM 1271 Data Decoupling Module”.

The power supplies are overload and short-circuit proof.

Benefits
Low-cost alternative solution for supplying AS-Interface networks while making full use of the maximum possible cable length per AS-i segment
Cost advantage particularly for multiple networks
Compact, space-saving dimensions
Reliable power supply even for large numbers of AS-Interface modules with high power requirements
Can be used worldwide thanks to, for example, UL/CSA approval (UL 508)
