Schneider Electric 140CPS11420 Modicon Quantum AC Summable Power Supply Module

Product Overview

The Schneider Electric 140CPS11420 serves as a high-capacity power supply module for the Modicon Quantum automation platform. This versatile unit operates in either standalone or summable (redundant) modes to provide stabilized 5.1V DC power to the backplane. By supporting summable configurations, it allows two power supplies to share the load or provide full redundancy, ensuring zero system downtime for high-availability process control. We provide this module as 100% brand new original hardware in factory-sealed packaging to ensure maximum service life and system integrity.

Engineering Advantages

• Summable Redundancy Architecture: This module supports "Summable" mode, enabling two 140CPS11420 units to work together on a single backplane. This configuration either doubles the available current to 20A for massive I/O clusters or provides 1+1 redundancy to protect against power module failure.

• Integrated Fault Signaling: A dedicated Normally Closed (NC) alarm contact monitors the module's health. This allows the control system to trigger immediate external sirens or SCADA alerts the moment a power fault occurs, facilitating rapid response before the process stops.

• Dual-Voltage Global Versatility: The module handles both 115V and 230V AC inputs. This flexibility simplifies spare parts inventory for global organizations, as a single part number supports facilities in both North American and European power regions.

• Clean Power for Sensitive I/O: By limiting harmonic distortion to 10%, the module provides stable, "quiet" power to the backplane. This prevents electrical noise from interfering with high-precision analog modules, ensuring the accuracy of your process data.

• Rugged Environmental Tolerance: Rated for continuous operation up to 60 °C (140 °F) and altitudes up to 5000 meters, this power supply survives the extreme conditions found in desert oil fields and high-altitude mining operations.

FAQs

• What is the difference between standalone and summable current ratings?

  In standalone mode, a single 140CPS11420 provides 11A to the backplane. In summable mode, two modules installed together provide a combined total of 20A. This allows you to scale the power as you add more I/O modules to the rack.

• Does this module require a specific fuse for installation?

  Yes. Schneider Electric recommends an associated 2A slow-blow fuse. This protects the module from high inrush currents (up to 38A at 115V) during initial power-up.

• How do I verify the power status locally?

  The front panel features a green "PWR OK" LED. If the LED remains dark while the input voltage is present, the internal overload or overvoltage protection has likely tripped, or the module has failed.

• Is this a genuine Schneider Electric part?

  Yes. We guarantee this 140CPS11420 is 100% Brand New original stock. It ships with the original GTIN 3595862017107 and remains factory-sealed to ensure it meets all UL 508 and CSA standards.
