Core Features High-Current Universal-Output Design for 24V DC Heavy Loads: Functions as a robust industrial-grade power supply optimized for North American 120V AC grids, converting input to a universal 24V DC output (marked “24DCU,” indicating broad compatibility with 24V DC devices). It delivers 10A rated current (240W power rating) with low output ripple (<50mVpp), ensuring stable power for heavy-duty 24V DC equipment like multiple small motors, large PLC systems, or dense actuator arrays that require high current and flexible compatibility. High Efficiency & Energy Savings: Equipped with advanced switch-mode technology to achieve ≥89% efficiency (at full load), minimizing energy waste and heat generation—critical for enclosed control cabinets where cooling is limited. The low no-load power consumption (<1.2W) further reduces standby energy use, aligning with global industrial efficiency standards (e.g., EN 61000-3-2) and lowering long-term operational costs. Comprehensive Protection for Heavy-Duty Gear: Integrates multi-layered protection mechanisms to safeguard the power supply and connected high-value equipment: Overload protection: Limits output current to 120–150% of rated value, with latching shutdown for sustained overloads (resettable via power cycle) to prevent component burnout. Short-circuit protection: Current-limited shutdown with automatic recovery once the fault is resolved, avoiding permanent damage to heavy-duty devices (e.g., motor drivers). Overvoltage protection: Clamps output voltage to ≤28V DC to shield 24V DC components (e.g., PLC modules, precision sensors) from 120V AC grid spikes. Basic EMI filtering: Built-in filters reduce conducted noise, preventing interference with nearby signal-sensitive devices (e.g., data loggers, communication modules). Wide Input Tolerance & Industrial Durability: Designed to handle unstable 120V AC inputs, supporting an input range of 85–132V AC (compatible with North American grids and voltage fluctuations). It operates reliably in temperatures from -20°C to +60°C, suitable for cold warehouses, warm production floors, or outdoor enclosures (with proper housing). The IP20 protection rating (IEC 60529) shields internal components from dust and accidental contact, while vibration resistance (10–500Hz, 50m/s²) ensures performance in high-vibration setups (e.g., manufacturing lines with heavy machinery). Space-Efficient Design & Easy Installation: Features a rugged, DIN-rail mountable form factor (35mm standard DIN rail) with a width of 60mm—balanced for high current and cabinet space efficiency. Tool-free heavy-duty screw terminal blocks enable secure wiring (accepts 10–16mm² cables for high-current connections), and a multi-color LED status indicator (green: normal; red: fault; yellow: overload warning) provides clear real-time monitoring—simplifying maintenance and troubleshooting for heavy-duty systems. Typical Applications The Phoenix Contact CM 175-PS-120AC-24DCU-10-2940443 is engineered for high-current universal 24V DC power delivery in North American 120V AC systems—ideal for heavy-duty scenarios where both high capacity and device compatibility are critical—with core use cases including: Multi-Motor & Driver Power: Powers 8–10 24V DC small motors (e.g., CKD AX series compact BLDC motors) and their drivers in large automation lines (e.g., conveyor systems, robotic workcells). The 10A output supports parallel motor operation and start-up surges, while the universal 24DCU output ensures compatibility with various driver models—complying with IEC 60034-1 standards for rotating electrical machines. Large PLC & Control System Power: Supplies power to large-scale PLCs (e.g., Allen-Bradley ControlLogix, Siemens S7-1500) and their peripheral racks (e.g., digital/analog I/O, communication processors, HMI panels) in industrial control rooms. The wide input tolerance handles grid fluctuations, and overload protection prevents PLC shutdown during peak load—complying with IEC 61131-2 standards for programmable controllers. Dense Actuator & Sensor Arrays: Powers hundreds of 24V DC industrial actuators (e.g., solenoid valves, pneumatic cylinders) and sensors (e.g., proximity sensors, vision cameras) in large manufacturing facilities (e.g., automotive assembly, electronics production). The high current supports dense deployment, while EMI filtering avoids signal interference—complying with IEC 60947-5-2 standards for industrial control devices. Heavy-Duty Portable Equipment: Serves as a power source for 24V DC heavy-duty portable equipment (e.g., mobile inspection robots, large test rigs) used in North American factories. The rugged design withstands transport vibrations, and the universal 24DCU output ensures compatibility with multiple device types—complying with IEC 60335-1 standards for electrical safety.
