Schneider 140CPS11420 Overview

Product Positioning:
The Schneider Electric Modicon Quantum 140CPS11420 is a dedicated power supply module designed for the Modicon Quantum PLC series. It provides stable DC power for the PLC base unit as well as its I/O, communication, and other sub-modules.

Input Voltage:
115 V or 230 V AC (switchable), compatible with 50/60 Hz power grids.

Output Voltage / Current:
Provides 5.1 V DC output with a rated current of 11 A (stand-alone supply) or 20 A (summable/redundant supply).

Power & Efficiency:
Rated power is approximately 130 VA with efficiency above 85%.

Protection Functions:
Built-in overvoltage, overload, and short-circuit protection, plus a power-failure warning output to enhance system safety.

Operating Environment:

• Operating temperature: −25 °C to +70 °C
• Storage temperature: −40 °C to +85 °C
• Humidity: 5%–95% (non-condensing)

Dimensions / Weight:
Approx. 75 mm × 130 mm × 116 mm; weight around 1.2 kg (varies slightly depending on manufacturer).

Installation Method:
DIN-rail mounting; supports stacking or redundant configuration. Two 140CPS11420 units can be combined for dual-power redundancy.

Typical Applications:
Discrete manufacturing, process industries, automotive production, energy, and infrastructure—any industrial automation system requiring a highly reliable power supply.

Key Advantages

Reliable Power Supply:
Designed specifically for Modicon Quantum, offering precise output voltage with low ripple to ensure stable operation of all PLC modules.

Redundancy / Summable Operation:
Supports stand-alone or parallel (summable) power supply operation to improve system fault tolerance.

Multiple Protection Features:
Overvoltage, overload, short-circuit protection, plus fault-warning signals to reduce downtime risks caused by power anomalies.

Compact Design:
Small footprint and lightweight construction make cabinet installation easier and more space-efficient.
