Schneider Electric 140CPS41400 Power Supply Unit: Application-Focused Overview

The Schneider Electric 140CPS41400 Power Supply Unit is engineered specifically for the rigorous demands of industrial automation systems. As an integral component of the Modicon Quantum platform, this power supply is designed to deliver consistent and reliable power, which is crucial for maintaining the performance of complex automation applications in sectors such as manufacturing, material handling, and packaging.

Practical Applications and Use Cases

In industrial environments where automation systems require uninterrupted power, the 140CPS41400 excels. Its summable configuration allows for the integration of multiple units, providing flexibility and scalability for larger installations. This feature is particularly beneficial in applications where power distribution needs to adapt to varying loads or where redundancy is critical to ensure system uptime.

The unit operates within an input voltage range of 48 to 60 V DC, accommodating diverse system requirements. With the capability to handle input currents up to 3800 mA, it ensures that even under high-demand conditions, power delivery remains stable. This is essential for processes that rely on precise timing and consistent power, such as robotics and conveyor systems.

Operational Benefits and Performance Characteristics

One of the standout features of the 140CPS41400 is its ability to manage brief power interruptions, with a hold-up time of 13 milliseconds at 48 V. This characteristic is vital in environments where voltage fluctuations can disrupt operations, as it prevents downtime and protects sensitive equipment from potential damage.

The unit’s output delivers a stable 5.1 V DC with a maximum current output of 8 A in summable mode, allowing for seamless operation of multiple devices. Internal overvoltage and overload protection mechanisms further enhance operational safety, ensuring that both the power supply and connected devices are safeguarded against adverse conditions.

Efficiency is a critical factor in industrial operations, and the 140CPS41400 is designed with a power dissipation of only 15.6 W. This low energy waste translates to reduced operational costs, making it an economically sound choice for long-term use in energy-sensitive applications.

Alarm and Signaling Features

The 140CPS41400 includes an alarm output feature with a normally closed (NC) contact rated at 6 A and 220 V, which activates during a power supply fault. This allows operators to quickly identify issues, minimizing response time and potential disruptions to production. Additionally, the green LED indicator labeled “PWR OK” provides immediate visual confirmation of
