Schneider Electric 140CPS11420 – Quantum PLC Rack Power Supply 20A

Brand ABB

Model Schneider 140CPS11420

The Schneider 140CPS11420 is a power supply module designed for the Modicon Quantum automation platform, delivering regulated 5.1 V DC output to backplane-mounted I/O modules, processors, and communication cards. As a member of Schneider Electric‘s widely deployed Quantum PAC series, the 140CPS11420 supports both standalone operation and summable configuration, allowing two identical power supplies to operate in parallel for increased current capacity. This flexibility makes the Schneider 140CPS11420 suitable for both small control systems with modest power demands and large, fully populated racks requiring maximum available current.

The 140CPS11420 accepts dual AC input ranges of 115 V and 230 V, accommodating common industrial supply voltages without external transformers or configuration changes. In standalone mode, the module provides 11 A at 60°C; when two Schneider 140CPS11420 units are installed in the same backplane, combined output reaches 20 A at 60°C . For mixed configurations, the 140CPS11420 may be paired with a 140CPS11410 to achieve 16 A total capacity, though identical model pairing is preferred .

The module incorporates internal overvoltage and overload protection, a normally closed alarm contact for fault signaling, and a green LED indicator for power status verification. The Schneider 140CPS11420 carries CE marking and complies with UL 508 and CSA C22.2 No. 142 standards, reflecting its suitability for industrial control environments .

Main Features and Advantages

Dual-Voltage AC Input Flexibility: The Schneider 140CPS11420 accepts both 115 V and 230 V AC input ranges without requiring jumper changes or external transformers. This design simplifies inventory management for facilities operating across different supply voltages and reduces commissioning time when deploying the 140CPS11420 in diverse industrial environments.

Summable Configuration for High-Current Applications: In systems where a single power supply cannot meet the total current demand of the backplane, two Schneider 140CPS11420 modules can be installed in the same rack to deliver up to 20 A at 60°C. The summable architecture also supports mixed pairing with the 140CPS11410 for 16 A combined output, providing a scalable power solution for expanding control systems .

Integrated Protection and Diagnostics: The 140CPS11420 features internal overvoltage and overload protection circuits, safeguarding connected Quantum modules from supply anomalies. A normally closed alarm contact enables external annunciation of power supply faults, while the front-panel green LED provides immediate visual confirmation of output status. These diagnostic features allow maintenance personnel to identify power issues without specialized test equipment .

Proven Quantum Platform Compatibility: As a core component of the Modicon Quantum PAC platform, the Schneider 140CPS11420 is engineered for seamless integration with Quantum processors, I/O modules, and communication cards. Its standard module format fits directly into Quantum backplanes, and its conformal coating (Humiseal 1A33) enhances resistance to environmental contaminants in industrial settings .
