Schneider Electric 140CPS11420 Modicon Quantum Power Supply Technical Guide
Product Introduction
The Schneider Electric 140CPS11420 is a dedicated power supply module within the Modicon Quantum series. Its primary role is converting AC line voltage into a stable DC output for the Quantum backplane. Specifically, this module takes either 115V AC or 230V AC input and produces a 5.1V DC output. The 140CPS11420 offers a maximum output current of 11A in standalone mode. Moreover, it can achieve 20A in a summable configuration when paired with a compatible unit.
Core Value
This module delivers several key benefits for industrial control systems. Firstly, its dual input voltage capability supports global deployment without hardware changes. Secondly, the summable feature provides flexibility for expanding system capacity. For instance, you can combine two 140CPS11420 units to increase total available current to 20A at 60°C. Furthermore, the module includes integral protection circuits. These protect against overvoltage and overload conditions, enhancing system reliability. The 140CPS11420 also features a green PWR OK LED for immediate visual status confirmation.
Technical Insights
Understanding the technical specifications of the 140CPS11420 ensures proper application. The input voltage range is 93-132V AC or 170-276V AC at 47-63 Hz. Nominal input current is 1.3A at 115V and 0.75A at 230V. Additionally, the inrush current can reach up to 38A at 115V and 19A at 230V. Consequently, selecting the appropriate external fuse is critical. Schneider recommends a 2A slow-blow fuse for protection. The output is a regulated 5.1V DC with an alarm relay output for fault signaling. A normally closed contact rated at 220V AC, 6A is available on the terminal strip.
Installation & Maintenance
Proper installation is crucial for the 140CPS11420 to function correctly. Before you insert or remove the module, you must disconnect line power from it. Failure to do so can result in equipment damage or personal injury. The module fits a standard Quantum rack slot. Furthermore, pay close attention to module orientation. Ensure correct alignment with the backplane connectors. During operation, maintain the ambient temperature range of 0°C to 60°C for optimal performance. Also, the storage temperature range is -40°C to 85°C. The module weight is approximately 0.65 kg, simplifying handling during installation.
