Schneider Electric 140CPS12400 Power Supply – Application-Focused Overview

The Schneider Electric 140CPS12400 power supply is engineered for critical industrial applications where reliability and continuous power are paramount. This robust power supply unit (PSU) is particularly suited for environments such as manufacturing plants, process automation systems, and other sectors that demand uninterrupted operation to avoid costly downtime and protect sensitive equipment.

Key Features and Operational Benefits

Designed in a standard module format, the 140CPS12400 integrates seamlessly into various industrial control systems. Its redundant power supply capability ensures that backup power is readily available in the event of a primary power failure, thereby enhancing system reliability. This feature is crucial in applications where even brief interruptions can lead to significant operational disruptions or safety hazards.

Input and Output Characteristics

The 140CPS12400 operates across a versatile input voltage range of 230 V AC (170 to 276 V) and 115 V AC (93 to 138 V), with a frequency range of 47 to 63 Hz. This adaptability allows it to function effectively within diverse power systems, making it suitable for global applications. The unit can handle inrush currents of up to 38 A at 115 V and 19 A at 230 V, ensuring it can accommodate power surges during startup without compromising performance. Additionally, its 2 A slow-blow fuse rating provides essential protection against overcurrent scenarios, safeguarding both the power supply and connected equipment.

The output specifications are equally impressive, delivering a steady 5.1 V DC with a power output capacity of 8 A at 60°C in redundant mode. This consistent output is vital for maintaining the operational integrity of sensitive devices. Built-in overvoltage and overload protections further enhance the safety of the connected systems, preventing damage from power spikes or excessive loads.

Performance and Reliability

A standout feature of the Schneider Electric 140CPS12400 is its low harmonic distortion level, which is maintained at less than or equal to 10% of the fundamental RMS value. This characteristic ensures clean power delivery, minimizing the risk of interference with sensitive electronic equipment. The inclusion of a green LED indicator (PWR OK) provides immediate visual feedback on power status, facilitating easier maintenance and monitoring for technicians.

Compliance and Certification

The 140CPS12400 is CE certified, indicating compliance with stringent European safety and performance standards. This certification not only assures users of its quality and reliability but also confirms its
