Configured for primary AC-to-DC voltage conversion in Advant OCS/800xA systems, the ABB SA910S 3KDE175131L9100 (SA910S Power Supply) provides direct physical/electrical execution.

Designator Mapping & Technical Structure

The hardware designator scheme specifies functional parameters across system subracks:

• SA910S: Main product designator for the regulated system power supply card.
• 3KDE175131L9100: Manufacturing part reference for subrack slot integration.
• PS24-Ex: Spare part designation cross-referenced to the 3KDE175131L9100 assembly.
• Tariff Code: 8537101190 for low-voltage industrial control power supplies.

Electrical & Environmental Data

Deterministic Network Bus & Hardware Integration

The module supplies regulated 24 VDC bus power across the local rack assembly to maintain uninterrupted CPU and I/O communication execution. High-density I/O density scaling and real-time data transfers across Profinet or EtherNet/IP deterministic networks rely on stable supply rails, avoiding communication drops. Onboard firmware flash compatibility and system rack logic supervision maintain steady backplane bus communication velocity during system power transients.

Subrack Mounting & Wiring Precautions

• AC Line Disconnection: Isolate external AC mains voltage before inserting or removing the power supply module from the rack slot.
• Grounding Connection: Ensure the panel enclosure earth stud connects directly to protective earth ground to maintain noise suppression.
• Convection Clearance: Maintain clear vertical airflow paths above and below the module heat sink to facilitate thermal dissipation.
• Terminal Screws: Torqued screw terminals on AC supply inputs to prevent high-resistance connections and local thermal buildup.

Frequently Asked Questions

• What range of AC input voltage does the SA910S 3KDE175131L9100 accommodate?

  The module accepts standard universal AC input sources ranging from 85 to 264 VAC at frequencies of 47 to 63 Hz.

• What output voltage is generated by the SA910S module for subrack loads?

  The unit provides a regulated 24 VDC bus output to power adjacent controller cards and I/O subrack modules.

• What is the peak inrush current limit during initial AC power-up?

  The integrated power supply input circuitry limits the cold-start inrush current to <= 20 A under full line loads.

• Can the SA910S module be hot-swapped while the rack backplane is energized?

  No. System power feeds must be isolated before pulling or inserting the power supply module to prevent internal arcing.

• How does the module maintain high electrical efficiency on AC mains?

  The unit incorporates active power factor correction circuitry yielding a power factor parameter of >= 0.95.

• What spare part model code corresponds to the 3KDE175131L9100 hardware?

  The manufacturing spare part cross-reference identifier for this power unit is PS24-Ex 3KDE175131L9100.

• What ambient temperature limits apply to operating hardware installations?

  The unit operates within industrial thermal limits specified from -25 to +70 deg C under non-condensing humidity.

• Does the power supply require external forced-air cooling fans?

  Convection cooling operates effectively provided standard vertical clearance dimensions around the module are maintained.
