Schneider Electric 140CPS12420: Powering Precision and Reliability

The 140CPS12420 is a reliable unit manufactured by Schneider Electric. This module falls under the category of Power Supplies, where it has carved a niche for itself with its cutting-edge features and unwavering performance.

Redundancy: Ensuring Continuous Power Flow

One standout feature is its redundant power supply type. Redundancy means ensuring an uninterrupted power supply. This becomes particularly crucial in settings where downtime is not an option.

Versatile Input Handling

The 140CPS12420 showcases its versatility in handling input voltages. Whether it's 230 V AC within the range of 170 to 276 V or 115 V AC ranging from 93 to 138 V, this power supply accommodates a spectrum of input scenarios. The flexibility extends to frequency as well, covering 47 to 63 Hz.

Current Dynamics: Balancing Act

Current specifications are equally significant. Drawing 600 mA at 230 V and 1100 mA at 115 V, the 140CPS12420 manages a delicate balance to meet varying power demands. The inrush current specifications of 38 A at 115 V and 19 A at 230 V emphasize its capability to handle initial power surges with finesse.

Power at its Core: VA Rating and Fuse Protection

At the core of its power handling capacity is the rated power in VA, standing tall at 130 VA. The associated fuse rating of 2 A slow-blow acts as a guardian, ensuring that the power supply remains resilient and secure.

Harmony in Power: Managing Distortion

Harmonic distortion, often a concern in power supplies, is masterfully managed by the 140CPS12420. With distortion levels kept below 10% of the fundamental RMS value, it guarantees a clean and stable power output.

Output Precision: A Steady 5.1 V DC

The 140CPS12420 delivers a steady 5.1 V DC. The power supply output current is specified at 10 A at 60 °C in redundant mode and 11 A at 60 °C in standalone mode, showcasing its reliability even under challenging conditions.

Internal Safeguards: Overvoltage and Overload Protection

Internally, the power supply is armed with protection mechanisms against overvoltage and overload. This not only preserves the longevity of the power supply but also shields connected devices from potential harm.

Cracking the Power Dissipation Code

Power dissipation is an integral aspect of any power system. The formula provided (6 + 1.5 x Iout, where Iout is in A) unravels the intricacies, offering engineers a tool to manage heat dissipation effectively.

Alert Systems: Proactive Fault Detection

The 140CPS12420 communicates through an alarm output—a normally closed (NC) contact capable of handling 6 A at 220 V. This feature provides a proactive means of detecting power supply faults. Meanwhile, a green LED serves as a local signal, offering a quick visual status check with the "PWR OK" signal.

CE Marking: Symbol of Compliance

The 140CPS12420 bears the CE compliance marking, affirming its adherence to European safety standards.

A Glimpse into the Specifications

This power supply comes with a 2-year warranty, a testament to MRO's commitment to quality and durability. Housed in a standard module format, it speaks volumes about its adaptability, fitting seamlessly into a myriad of applications.

In conclusion, the Schneider Electric Power Supply with part number 140CPS12420 is more than a mere component; it's a powerhouse that exemplifies precision, adaptability, and reliability. Schneider Electric's commitment to innovation and quality is encapsulated in this power supply, making it a stalwart choice for diverse industrial and commercial applications.
