Description
Schneider 140CPS11100
Schneider 140CPS11100 is a rack power supply module designed specifically for the Quantum series PLC and automation equipment. It provides a stable 5.1VDC output, features wide-range input voltage, overcurrent and overvoltage protection, and high reliability. Its modular design facilitates installation and maintenance, making it a core component for supplying stable power to Quantum racks and various modules in industrial automation applications.
1. Positioning and System Relationship
System Affiliation
Belongs to the Modicon Quantum series of Schneider Electric, model 140CPS11100, classified as a Rack Power Supply Module. It features a modular design, is compatible with standard Modicon Quantum racks, and complies with Quantum system architecture specifications. It cannot operate independently and must be installed in a designated slot of a Quantum rack to provide centralized power for all modules in the rack.
Core Role
Positioned as the “power supply core” of the Quantum rack, its core responsibilities:
- Convert a wide input voltage range of 120~230V AC into a stable 5.1VDC output to supply reliable power to the Quantum rack backplane, CPU modules, I/O modules, and other small automation devices;
- Provide overcurrent and overvoltage protection to prevent damage to internal rack modules caused by abnormal voltage;
- Support wide-range voltage input to adapt to different power grid environments;
- Provide real-time power status feedback via status indicators for convenient operation and maintenance monitoring.
Mounting Position
Designed to standard DIN rail mounting dimensions, it is exclusively installed in the leftmost slot (Slot 0) of the Quantum rack — the dedicated slot for rack power supply to ensure priority power distribution. The module is equipped with wiring terminals (L/N input, PE grounding) for easy wiring. A green PWR OK status indicator on the front panel provides intuitive feedback on whether power supply is normal. The modular design allows quick installation, maintenance, and replacement.
System Architecture
Integrated into the Quantum system power supply chain:120~230V AC power grid → 140CPS11100 power supply module (voltage conversion, protection) → Quantum rack backplane → CPU modules, I/O modules and other automation devices in the rack.At the same time, the module’s built-in protection mechanism monitors input/output voltage and current status in real time and cuts off power promptly in case of abnormality, forming a complete power supply closed loop of “grid input – voltage conversion – stable power supply – safety protection” to ensure stable operation of the entire Quantum system.
2. Functions and Technical Features
1. Stable Power Supply and Voltage Conversion
- Input voltage: Supports a wide input range of 120~230V AC (compatible with 100~276V, 47~63Hz), adapting to different regions and power grid environments without additional voltage conversion equipment.
- Output specifications: Provides stable 5.1VDC output with 3A output current, meeting the power supply requirements of standard Quantum racks and various modules, and delivering centralized power to the rack backplane.
- Conversion efficiency: Uses high-quality components with high voltage conversion efficiency, low energy consumption, reduced power loss, and lower overall system operating costs.
2. Multiple Safety Protections
- Overcurrent protection: Automatically triggers protection and cuts off output when output current exceeds the rated value, preventing damage to the module and other equipment in the rack due to overload.
- Overvoltage protection: Cuts off power promptly when input voltage rises abnormally or output voltage exceeds the set range, avoiding high-voltage surges that damage precision components such as CPU and I/O modules.
- Grounding protection: Equipped with a PE protective grounding terminal that must be securely connected to enhance system safety and prevent risks such as electric leakage and static electricity.
3. High Reliability and Usability
- High reliability: Adopts high-quality electronic components and mature circuit design, ensuring stable operation even in harsh industrial environments and uninterrupted power supply.
- Modular design: Compact structure and integrated modularity simplify installation, maintenance, and replacement, enabling quick swap of faulty modules and reducing system downtime.
- Status monitoring: Front-mounted green PWR OK status indicator — steady on means normal power supply, off or abnormal flashing indicates a power fault, allowing maintenance personnel to quickly troubleshoot issues.
4. Industrial-Grade Environmental Adaptability
- Operating temperature: 0~60℃, suitable for high and low temperature on-site industrial environments, ensuring stable operation without additional cooling equipment.
- Anti-interference capability: Excellent electromagnetic interference (EMI) protection, adapting to strong on-site industrial interference and ensuring stable power supply.
