Schneider 140CPS11100 Modicon Quantum power supply module

Product Overview

The Schneider Electric 140CPS11100 serves as a high-efficiency standalone power supply for the Modicon Quantum automation platform. It converts 120V to 230V AC wide-range input into a regulated 5.1V DC output to energize the Quantum backplane and attached I/O modules. Designed for high-availability industrial environments, this module features built-in protection circuitry to safeguard sensitive logic components from power fluctuations. We supply this unit as 100% Brand New and Original, ensuring your control system operates with the factory-specified stability required for critical infrastructure.

Technical Specifications

The 140CPS11100 provides consistent power delivery across a broad temperature range and supports varying AC input frequencies.

Engineering Advantages

• Wide Voltage Tolerance: The module accepts AC inputs from 100V to 276V. This wide window handles significant voltage sags and surges common in heavy industrial grids without interrupting the PLC CPU or I/O performance.

• Integrated Hardware Protection: Internal overvoltage and overload protection circuits automatically monitor the output. If a downstream fault occurs, the module limits current to prevent permanent damage to the expensive processor and communication cards on the backplane.

• Efficient Thermal Management: This module minimizes heat generation, dissipating power according to the load. At full 3A output, the unit maintains a low thermal footprint, allowing for high-density rack configurations even in non-air-conditioned cabinets.

• High-Altitude Capability: Unlike standard consumer-grade power supplies, the 140CPS11100 operates reliably at altitudes up to 5,000 meters (16,404 ft). This makes it the standard choice for mining and high-elevation utility applications.

• Rapid Diagnostics: The "PWR OK" LED provides immediate visual confirmation of the power stage health. This simplifies initial commissioning and reduces the time required for field technicians to identify power-related faults.

FAQs

• Can I use the 140CPS11100 in a redundant power configuration? No. This is a standalone power supply. For redundancy (Summable or Redundant configurations), you must use specific modules like the 140CPS114x or 140CPS124x series designed for load-sharing and parity.

• Does this module require a specific fuse for protection? Yes. Schneider Electric recommends an external 1.5 A slow-blow fuse to protect the input circuitry from upstream spikes and short circuits.

• Will this module power an entire Quantum rack with 16 modules? It depends on the total current draw of your specific I/O modules. The 140CPS11100 provides 3A at 5.1V DC. You must calculate the sum of the "Bus Current Required" for all modules in the rack to ensure it does not exceed the 3A limit.

• Is this module compatible with both old and new Quantum backplanes? Yes. The 140CPS11100 utilizes the standard Modicon Quantum format and is compatible with all Quantum backplanes (e.g., 140XBP series).
