Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 140CPS11420 is a Schneider Modicon Quantum power supply module, order code 140CPS11420, accepting 115/230 VAC input and delivering a regulated 5.1 VDC output at 11 A with a 130 VA rating. It is designed for the Quantum automation platform and can operate as a standalone unit or be summed with another supply for redundant or higher-current configurations. This module converts 115/230 VAC line power to a 5.1 VDC bus that powers the Quantum rack and its I/O modules. The 11 A output current and 130 VA rating define the total load the supply can support — enough for a fully populated local rack with a mix of discrete and analog modules. An internal output overload protection circuit handles fault conditions without external fusing, though a 2 A slow-blow fuse is specified for the AC input line. A green LED (PWR OK) on the front panel indicates the supply is delivering nominal voltage. The alarm output is a normally-closed contact rated 6 A at 220 V, wired to signal a power supply fault to the PLC or a remote annunciator. Harmonic distortion on the AC line must stay at or below 10 % of the fundamental RMS value for reliable operation. ## Applications The 140CPS11420 sits in the backplane of a Modicon Quantum rack, providing the DC logic power for the CPU and all expansion modules in that chassis. It is used across process and discrete automation — water treatment, material handling, packaging, and oil & gas skids — wherever a Quantum-based control system is deployed. The summable feature allows two supplies to share the load for redundancy or to increase available current in a high-I/O-count rack. ## Compliance & certifications The 140CPS11420 carries CE marking and is certified to UL 508 and CSA C22.2 No 142. It also holds cUL certification and is listed under California Proposition 65. These certifications cover the module for installation in industrial control panels destined for North American and European markets.","metaTitle":"Schneider 140CPS11420 Modicon Quantum Power Supply, 115/230 VAC, 5.1 VDC, 130 VA","metaDescription":"Schneider Modicon Quantum 140CPS11420 power supply module: 115/230 VAC input, 5.1 VDC output, 11 A, 130 VA, CE, UL 508, CSA.
