Schneider 140CPS52400 redundant power supply module

Product Description

The 140CPS52400 is a high-reliability redundant power supply module designed for the Schneider Electric Modicon Quantum automation platform. Engineered for critical mission-control applications, this module ensures continuous system uptime by providing a stable 5.1V DC output to the Quantum backplane. With its redundant architecture, the 140CPS52400 allows multiple power supplies to share the load or act as an immediate backup, preventing system failure in the event of a single supply outage. Its robust design is optimized for high-performance industrial environments requiring maximum availability.

Key Engineering Features

• Fault-Tolerant Redundancy: Specifically designed to work in tandem with another redundant power supply on the same backplane, ensuring that power to the CPU and I/O modules is never interrupted during a hardware failure.

• Efficient Thermal Management: Power dissipation is calculated as $6 + (1.5 \times I_{out})$, where $I_{out}$ is the current in Amperes, allowing for precise heat load calculations within the control cabinet.

• Hazardous Location Certified: Carries FM Class 1 Division 2 certification, making it suitable for use in environments where flammable gases or vapors may be present.

• High-Altitude Performance: Qualified for operation at altitudes up to 5,000m, exceeding standard industrial equipment limits and allowing for deployment in specialized high-altitude facilities.

• Robust ESD Immunity: Tested to IEC 801-2 standards (4 kV contact, 8 kV air), providing high resistance to electrostatic discharge in dry or high-interference industrial settings.
