Core Features Universal-Output AC-DC Design for Flexible 24V DC Loads: Functions as a versatile industrial-grade power supply optimized for North American 120V AC grids, converting input to a universal 24V DC output (marked “24DCU,” indicating broad compatibility). It delivers 5A rated output current (120W power rating) with low output ripple (<50mVpp), ensuring stable power for medium-duty 24V DC equipment like small motors, PLC modules, or multi-sensor arrays that require flexible voltage adaptation. High Efficiency & Low Standby Energy: Equipped with switch-mode technology to achieve ≥86% efficiency (at full load), minimizing energy waste and heat generation—critical for enclosed control cabinets with limited cooling. The low no-load power consumption (<0.8W) further reduces standby energy use, aligning with global industrial efficiency standards (e.g., EN 61000-3-2) and lowering operational costs. Comprehensive Protection for Medium-Duty Gear: Integrates multi-layered protection mechanisms to safeguard the power supply and connected equipment: Overload protection: Limits output current to 120–150% of rated value, with automatic recovery after fault removal to prevent damage to medium-value devices (e.g., motor drivers). Short-circuit protection: Current-limited shutdown with automatic recovery once the fault is resolved, avoiding permanent component damage. Overvoltage protection: Clamps output voltage to ≤28V DC to shield 24V DC components (e.g., sensors, PLC I/O) 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). 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 or warm production floors. The IP20 protection rating (IEC 60529) shields internal components from dust and accidental contact, while vibration resistance (10–500Hz, 30m/s²) ensures performance in mobile or high-vibration setups. Compact Form & Easy Installation: Features a slim, DIN-rail mountable design (35mm standard DIN rail) with a width of 45mm—balanced for medium current and space efficiency. Tool-free terminal blocks enable quick, secure wiring (accepts 4–10mm² cables), and a bright LED status indicator (green: normal; red: fault) allows instant visual monitoring—reducing installation time and simplifying troubleshooting for medium-duty systems. Typical Applications The Phoenix Contact CM 125-PS-120AC-24DCU-5-2942496 is engineered for universal 24V DC power delivery in North American 120V AC systems—ideal for medium-duty scenarios where flexibility and grid adaptability are key—with core use cases including: Small Motor & Driver Power: Powers 24V DC small motors (e.g., CKD AX series compact BLDC motors) and their drivers in automation lines (e.g., conveyor sections, robotic end effectors). The 5A output supports motor start-up surges, while the universal 24DCU output ensures compatibility with various driver models—complying with IEC 60034-1 standards for rotating electrical machines. Compact PLC & Control Systems: Supplies power to compact PLCs (e.g., Allen-Bradley Micro800, Siemens S7-1200) and their peripheral modules (e.g., digital I/O, communication cards) in North American control panels. 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. Multi-Sensor Array Power: Powers 25–30 24V DC industrial sensors (e.g., proximity sensors, photoelectric sensors) in manufacturing lines (e.g., electronics assembly, packaging). The medium-current output supports dense sensor deployment, while EMI filtering avoids signal interference—complying with IEC 60947-5-2 standards for industrial control devices. Portable Industrial Equipment: Serves as a power source for 24V DC portable equipment (e.g., mobile test kits, small inspection robots) used in North American factories. The compact size enables easy transport, and the universal 24DCU output ensures compatibility with multiple device types—complying with IEC 60335-1 standards for electrical safety.
