Schneider 140CPS11420 Quantum AC Power Supply Module

Schneider 140CPS11420 Modicon Quantum AC Power Supply Module

Product Introduction

This power supply module provides flexible and robust power for your Modicon Quantum automation system. It accepts worldwide AC input voltages, making it suitable for global installations. The 140CPS11420 supports both standalone and summable modes, allowing you to scale power delivery based on your rack's requirements. Additionally, a dedicated alarm output notifies you immediately of any power faults, minimizing downtime.

Technical Specifications

The 140CPS11420 accepts two distinct AC input ranges. It operates on 115V AC within 93 to 132V at 47-63 Hz, or on 230V AC within 170 to 276V. Input current draws measure 1300 mA at 115V and 750 mA at 230V. Furthermore, this unit handles inrush currents up to 38A at 115V and 19A at 230V. For protection, we recommend an external 2A slow-blow fuse.

On the output side, this power supply generates a stable 5.1V DC. Its output current capability depends on the configuration. In standalone mode, it delivers 11A continuously. Meanwhile, in summable mode, it provides up to 20A, letting you combine multiple units for higher power demands. The module includes internal overvoltage and overload protection for comprehensive safety.

Alarm and Monitoring Features

This unit includes a valuable alarm output feature. It provides one normally closed (NC) contact rated at 6A at 220V, which triggers upon a power supply fault. Consequently, you can connect this alarm to a PLC input or a warning light for immediate fault detection. A single green LED also offers local visual confirmation, showing the "PWR OK" status clearly.

Mechanical and Environmental Specifications

The Schneider 140CPS11420 handles demanding industrial conditions effectively. It operates reliably within a temperature range of 0°C to 60°C and tolerates storage temperatures from -40°C to 85°C. Moreover, the unit supports up to 95% relative humidity without condensation and functions at altitudes up to 5000 meters. Its robust design resists electrostatic discharge and electromagnetic fields, complying with IEC 801-2 and IEC 801-3 standards.

Installation and Setup

Installing this module requires careful attention to the input voltage selection. First, verify that your AC mains supply matches the unit's input rating. Next, power off the system completely. Then, insert the 140CPS11420 firmly into the designated slot on the Modicon Quantum backplane until it seats securely. Afterward, connect your AC power source to the appropriate terminals, observing correct wiring. Finally, apply power; the green LED illuminates, confirming the module is ready for operation.
