Schneider Electric Modicon Quantum 125V DC Redundant Power Supply Module | 140CPS52400

Product Overview

The 140CPS52400 provides high-availability DC power for the Schneider Electric Modicon Quantum backplane and resident I/O modules. Designed for mission-critical applications, this redundant power supply module converts a 125V DC source into a stable 5.1V DC bus voltage. It supports multi-module configurations to ensure the system remains operational even if one power unit fails. We supply this module as 100% Brand New and Original factory stock, meeting the rigorous demands of power generation, substation, and heavy industrial automation.

Technical Specifications

The 140CPS52400 utilizes advanced voltage regulation to handle high-voltage DC inputs:

Engineering Advantages

• Redundant System Architecture: This module allows the installation of two power supplies on a single backplane. This configuration creates a fault-tolerant power bus; if one module loses input or fails internally, the second unit assumes the full load without interrupting the CPU or I/O operations.

• High-Voltage DC Input Compatibility: The 125V DC input range (100-150V) specifically targets utility and substation environments where station batteries provide the primary control power. This eliminates the need for intermediate AC/DC conversion hardware.

• Comprehensive Internal Protection: Built-in overvoltage and overload circuitry shield the expensive Quantum backplane from electrical faults. These internal safeguards prevent downstream damage to processors and communication modules during field-side power surges.

• Optimized Thermal Performance: The module manages power dissipation through a linear calculation ($6 + 1.5 \times Iout$). This predictable thermal footprint assists engineers in calculating cabinet cooling requirements for high-density rack configurations.

• Simplified Diagnostics: A single, high-visibility green LED (PWR OK) provides immediate confirmation of the 5.1V DC bus health. This simplifies routine maintenance walk-throughs and accelerates fault isolation during system outages.

FAQs

• Can I use the 140CPS52400 as a standalone power supply?

  Yes. While designed for redundancy, a single 140CPS52400 can power a Quantum rack as long as the total bus current requirement does not exceed 8 A.

• What is the difference between "Summable" and "Redundant" Quantum power supplies?

  Summable supplies (like the 140CPS21400) allow you to combine currents to reach a higher total (e.g., 8A + 8A = 16A). Redundant supplies like the 140CPS52400 ensure that if one unit fails, the remaining unit handles the entire load. You must not exceed 8A total load for true redundancy with this module.

• Is there a specific fuse requirement for the input line?

  Schneider Electric requires a 2 A slow-blow fuse for the 125V DC input. Using the correct fuse rating prevents nuisance tripping caused by the 28 A inrush current while protecting the module from sustained overcurrent.

• Is this product a refurbished or used unit?

  No. We guarantee every 140CPS52400 is 100% Brand New and arrives in original factory packaging with all manufacturer quality assurance markings intact.
