PSN130S 30 V power supply units for 3 A, 4 A and 8 A

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" в†’ "DCM 1271 Data Decoupling Module".

The power supplies are overload and short-circuit proof.

Dimensions

The 30 V power supply units have compact dimensions in widths of 50 and 70 mm. No distances to other devices must be observed during the installation.

Features

• Primary-clocked power supplies for connecting to a single-phase AC power supply system
• Power for currents of 3 A, 4 A and 8 A
• The output voltage is floating, and resistant to short-circuits and no-load operation. If there is an overload, the output voltage is reduced or cut-off. After a short-circuit or overload, the devices start up again automatically.
• In the event of a device fault, the output voltage will be limited to max. 37 V.
• Modular installation devices in degree of protection IP20 and safety class I
• Diagnostics: With an output voltage > 26.5 V DC, the green LED (30V O.K.) is lit and the signaling contact 13-14 is closed.
