Schneider Electric Modicon Quantum 140CPS21400C: Primary Power Supply Module
The 140CPS21400C is a core component of the Schneider Electric Modicon Quantum series PLC system. Designed to deliver stable and reliable DC power, this module ensures the continuous operation of the CPU unit and communication modules across a wide range of industrial environments.
Typically designated as the Primary Power Supply, it is often paired with a backup unit (such as the 140CPS22400C) to establish a redundant power configuration, maximizing system uptime and reliability.
Key Features & Technical Specifications
Electrical Characteristics
- Voltage Range: Supports 24 V DC input. (Alternative models also support 115/230 V AC depending on the specific variant.)
- Output Current: Provides a typical output current of 8A, sufficient to power most Quantum CPUs and their associated peripheral devices.
- Power & Efficiency: Utilizes high-efficiency switching power supply technology. It features a high power factor (PF) and superior efficiency, resulting in reduced energy consumption and lower heat dissipation within the control cabinet.
Physical Specifications & Installation
- Standardized Form Factor: Built to the standard Modicon Quantum form factor (typically 170mm x 100mm x 115mm), allowing for seamless installation alongside other modules such as I/O modules and communication adapters.
- Industrial Protection: Engineered with industrial-grade protection, the unit is resistant to dust, liquid splashes, and electromagnetic interference (EMI), making it suitable for harsh field environments.
System Compatibility & Redundancy
- System Compatibility: Specifically designed for the Modicon Quantum series to ensure precise voltage and current matching with the CPU and backplane.
- Redundant Configuration: For applications demanding high availability, this module is commonly used with the 140CPS22400C (24V DC Redundant Power Supply) . In such setups, the system automatically switches to the backup supply if the primary unit fails, preventing unexpected downtime.
Applications
- Industrial Automation: Ideal for PLC control panels, automated production lines, and process control systems.
- Harsh Environments: Suitable for environments subject to high temperatures, humidity, vibration, and electromagnetic disturbances.
