Schneider Electric 140CPS42400 Power Supply: Application-Focused Overview

The Schneider Electric 140CPS42400 power supply is engineered for high-performance applications in industrial automation, particularly within the Modicon Quantum platform. Its redundant design is crucial for environments where power reliability is non-negotiable, such as manufacturing lines, process control systems, and critical infrastructure operations. This unit ensures uninterrupted power delivery, effectively addressing the engineering challenge of maintaining system stability during power disruptions.

Operational Benefits and Performance Characteristics

With an input voltage range of 48 to 60 V DC, the 140CPS42400 is adaptable to various industrial power conditions, making it suitable for diverse setups. The unit's input current rating of 3800 mA guarantees a consistent power supply to connected devices, which is essential for maintaining operational integrity in automated systems. During startup, the capability to handle an inrush current of 14 A at 40 V provides essential surge protection, safeguarding sensitive components from potential damage.

In scenarios where input power interruptions occur, the 140CPS42400 can sustain operation for 13 milliseconds at 48 V. This brief hold-up time is critical in preventing system faults and ensuring that connected devices remain operational during transient power fluctuations. Additionally, the unit features a 2 A time-lag fuse, which protects against overcurrent conditions, enhancing the overall safety and reliability of the power supply.

The output specifications of the 140CPS42400 include a voltage of 5.1 V DC and a maximum output current of 8 A in redundant mode. This redundancy allows multiple units to operate in parallel, ensuring continuous power supply even if one unit fails. Such a feature is vital for applications in sectors like pharmaceuticals, food processing, and automotive manufacturing, where power stability directly impacts product quality and safety.

Protection Features and Efficiency

Designed with robust protection mechanisms, the 140CPS42400 includes internal overvoltage and overload safeguards, which are essential for protecting both the power supply and the connected equipment from power surges and current overloads. These features ensure that the unit can operate efficiently under demanding conditions, reducing the risk of downtime due to electrical faults.

The power dissipation rating of 17.2 W indicates that the 140CPS42400 is optimized for energy efficiency, minimizing wasted power while delivering reliable performance. This efficiency is particularly beneficial in large-scale industrial operations where energy costs can significantly impact overall operational budgets.
