Schneider Electric 140CPS21100 Power Supply Unit

The Schneider Electric 140CPS21100 power supply unit is engineered for demanding industrial applications, offering a robust and reliable solution for powering critical automation systems. As part of the Modicon Quantum automation platform, this power supply is designed to meet the rigorous demands of modern industrial environments, ensuring stable and efficient operation across various applications.

Input and Output Specifications

Operating within an input voltage range of 20 to 30 V DC, with a nominal voltage of 24 V DC, the 140CPS21100 delivers a consistent input current of 1600 mA. This capability is essential for maintaining reliable energy supply to connected devices, particularly in systems where power stability is crucial. The unit can handle inrush currents of up to 30 A during start-up, enabling it to accommodate high current demands without risking overload, which is a common challenge in industrial settings.

The power supply is designed to tolerate brief input power interruptions, with the ability to sustain functionality during dips of up to 20 milliseconds at 25 V and one millisecond at 20 V. This feature is particularly beneficial in environments prone to transient power fluctuations, ensuring that automation processes remain uninterrupted. Additionally, a 2.5 A slow-blow fuse protects against overcurrent conditions, enhancing operational safety and reliability.

On the output side, the 140CPS21100 provides a stable 5.1 V DC output voltage with an output current range of 0.3 to 3 A in standalone mode. This versatility makes it suitable for powering a variety of automation components, from sensors to control systems, ensuring they operate effectively under varying load conditions. The unit also incorporates internal protections against overvoltage and overload, safeguarding both the power supply and connected devices from potential damage during irregular operating conditions.

Efficiency and Power Dissipation

Efficiency is a critical factor in power supply performance, and the 140CPS21100 excels in this area. Its power dissipation formula, 2 + (3 x Iout), where Iout is the output current in amperes, ensures minimal energy loss, contributing to lower overall operating costs. This efficiency is vital for industrial operations where energy consumption directly impacts profitability and sustainability.

Visual and Safety Indicators

The design of the 140CPS21100 includes a straightforward visual indicator—a green LED labeled "PWR OK"—which provides immediate feedback on the power supply's operational status. This feature facilitates quick troubleshooting
