Description

The SCHNEIDER 140CPS12400 is a high-performance redundant power supply module designed for Schneider Electric’s Modicon Quantum automation platform, delivering critical 24V DC power to PLC racks in industrial control systems. Engineered for mission-critical applications, this module features dual independent AC/DC inputs with automatic load sharing and seamless failover (<2ms>140CPS12400 supports hot-swapping without tools using integrated quick-release levers – essential for minimizing downtime in continuous processes like power generation or chemical manufacturing. With a wide input voltage range (85-264V AC/DC) and active power factor correction (PFC >0.95), it stabilizes power for Quantum CPUs, I/O modules, and communication networks even in unstable grid conditions.

This power supply provides comprehensive diagnostics through front-panel LEDs and Modbus communication, monitoring output voltage ripple (<100mV>SCHNEIDER 140CPS12400 achieves IP20 protection and operates in -25°C to 70°C environments with 95% humidity tolerance, making it suitable for harsh locations like steel mills or offshore platforms. Its forced-air cooling with speed-controlled fans optimizes thermal management while maintaining noise levels below 55 dBA. Conforming to IEC 61131-2 standards, this module enables N+1 redundancy configurations and integrates seamlessly with Quantum’s X80 racks.

Technical Specifications

Main Features and Advantages

True Redundancy Architecture: Dual independent power conversion circuits with decentralized current sharing ensure zero-interruption transfer during single-module failure. The 140CPS12400 maintains full 10A output even if one supply fails – critical for safety shutdown systems.

Advanced Diagnostics: Real-time monitoring of voltage deviation (±0.5V), temperature hotspots, and fan speed. Status LEDs indicate input health (green), output active (yellow), and faults (red). Modbus registers provide predictive maintenance data for load trends.

Robust Environmental Performance: Corrosion-resistant coating withstands H₂S atmospheres in refineries. Vibration immunity (2g @ 10-500Hz) ensures stability near rotating machinery. Fan speed automatically adapts to ambient conditions (-25°C cold-start capable).

Simplified Maintenance: Tool-less hot-swap design allows module replacement in <60>

Safety Compliance: Reinforced isolation (3kV AC input-output) meets EN 50178. Short-circuit protection limits current to 12.5A. ATEX certification enables installation in Zone 2 hazardous areas.

Application Field

The SCHNEIDER 140CPS12400 secures power for critical automation:

Energy: Feeds turbine control cabinets in nuclear/fossil plants, surviving grid transients

Oil & Gas: Powers offshore platform safety systems (SIL 2) with salt fog resistance

Water Management: Ensures continuous operation of pump station PLCs during storms

Manufacturing: Supports automotive production line robots during voltage dips

Mining: Energizes conveyor control systems in dusty environments

Chemical: Maintains reactor batch sequencing during generator transfers

Installation and Maintenance

Pre-installation preparation: Verify rack compatibility (supports 140XBP/140XCP series). Separate AC inputs from different sources for true redundancy. Torque terminals to 0.6 N·m using 14-12 AWG wire. Maintain 50mm clearance above/below for airflow.

Maintenance recommendations: Quarterly cleaning of air filters with compressed air. Annual calibration check (±1% output tolerance). Replace fans if speed drops >20% or noise exceeds 60 dBA. Test failover biannually by disconnecting primary input under load. Store spares in climate-controlled (<40>
