The Schneider Electric 140CPS51100 is a high-performance power supply module designed for use within the Modicon Quantum series of Programmable Logic Controller (PLC) systems. Engineered specifically for industrial control applications, this module supplies a regulated output voltage to power backplane components and other modules installed in the PLC rack. It is a DC input module, accepting a voltage input in the range of 100 to 150 VDC and converting it into a stable 5.1 VDC output with a current capacity up to 3 A.
Positioned as a reliable and robust power solution, the 140CPS51100 is often deployed in control systems requiring dependable and uninterrupted power to PLC modules. Its form factor is fully compatible with the Quantum platform, and its electrical characteristics are tailored to ensure operational consistency in demanding environments.
Accepts a DC voltage input from 100 to 150 VDC.
Designed to tolerate fluctuations in industrial DC power sources without compromising output performance.
Provides a constant output of 5.1 VDC.
Delivers up to 3 A of output current, which is sufficient for powering multiple modules in the same rack.
Equipped with overvoltage and overload protection circuits to ensure safety and long life of both the power supply and connected modules.
Manages high inrush current conditions—rated for up to 10 A inrush current at startup—without causing system instability.
Designed to sustain input voltage drops or brief interruptions up to 1 millisecond without output failure.
Built to maintain high output integrity even under continuous load or in high-temperature environments.
Features a green “PWR OK” LED indicator on the front panel, enabling fast verification of power status by maintenance staff.
Standard Quantum modular rack-mount format allows for seamless mechanical and electrical integration.
Weighs approximately 0.65 kg, enabling easy installation and replacement.
Operates in temperatures ranging from -20°C to +60°C.
Tolerates up to 95% relative humidity (non-condensing), making it suitable for both indoor and sheltered outdoor control enclosures.
Complies with CE requirements and other global industrial electrical safety standards.
Suitable for deployment in applications subject to regulatory inspection or certification.
The 140CPS51100 is deployed across a broad range of industrial sectors. It is particularly suited for applications where system stability and power reliability are essential:
Manufacturing Plants: Supports automation systems used in automotive, packaging, food processing, and electronics assembly lines.
Water and Wastewater Treatment: Powers process control systems for filtration, pumping, and chemical dosing.
