Schneider 140CPS51100 | Modicon Quantum 125V DC Power Supply

Schneider Electric 140CPS51100 Modicon Quantum 125V DC Standalone Power Supply

The 140CPS51100 (Model: 140CPS51100) is a dedicated standalone power supply module designed for the Schneider Electric Modicon Quantum automation platform. Optimized for high-voltage DC environments, this module converts a nominal 125 V DC input (ranging from 100 to 150 V DC) into a stabilized 5.1 V DC output for the PLC backplane. The 140CPS51100 (Part Number: 140CPS51100) is the primary choice for power utilities and substation automation, where 125 V DC battery banks are the standard for control power.

Unlike summable or redundant modules, the 140CPS51100 (Standalone Module: 140CPS51100) operates as an independent power source for smaller to mid-sized Quantum racks. It provides a reliable output current range of 0.3 A to 3 A. Built with industrial-grade safety features, it includes internal overvoltage and overload protection to safeguard the CPU and I/O modules from input transients. Its standard module format ensures a compact footprint while delivering the "Expertise" and reliability expected in mission-critical infrastructure.

Detailed Technical Specifications

The 140CPS51100 (140CPS51100) is engineered for precision voltage conversion in DC-powered control systems.

Note on Data Accuracy: Some technical sources incorrectly list this as an AC module with 16A output. Correct engineering data confirms the 140CPS51100 is a 125V DC input module with a standalone output of 3A.
