2. Key Features

• Universal Input (100V~240V AC): Eliminates voltage selectors, enabling seamless installation in global markets (e.g., 110V AC in North America, 230V AC in Europe/Asia) without hardware modifications, reducing inventory complexity.
• Stable 24V DC Output: ±2% voltage accuracy and ≤100mVpp ripple ensure clean power for sensitive ABB components—prevents data corruption in I/O modules (e.g., AI893 analog measurement errors) and communication failures in fieldbus interfaces (e.g., CI801).
• Fan-Free Convection Cooling: Maintenance-free operation with no moving parts—avoids dust accumulation (critical in manufacturing environments) and eliminates fan-related failure points, extending service life to 10+ years.
• Compact DIN Rail Design: 70mm-wide form factor fits standard 35mm DIN rails—saves 40% space compared to bulkier power supplies, enabling dense installation alongside S800 I/O racks, termination units (e.g., TU860), and circuit breakers (e.g., S203-B25).
• 3kV Input-Output Isolation: Prevents ground loops and noise transfer between input power and connected devices—critical in industrial facilities with distributed ground potentials (e.g., factory floors with multiple machinery grounding points).
• Wide Environmental Tolerance: -25℃~+70℃ operating range and 1g vibration resistance—operates reliably in extreme conditions: cold storage (food processing), high-temperature process zones (refineries), and mobile equipment (construction machinery).
• Seamless ABB Compatibility: Tested for integration with ABB 800xA DCS, AC800M PLCs, and S800 I/O modules—ensures plug-and-play functionality without voltage mismatches or compatibility issues with ABB control components.

3. Application Fields

• ABB Automation Component Power Supply: Primary application—powering low-voltage ABB devices:
  • Industrial Control Cabinets: Supplies 24V DC to S800 I/O modules (DI825, AI893) and TU860 termination units; stable output ensures accurate analog signal measurement (e.g., reactor pressure) and reliable digital input detection (e.g., emergency stops).
  • AC800M PLC Peripherals: Powers CI801 fieldbus interfaces and operator panel accessories; 3kV isolation prevents noise from factory power grids interfering with fieldbus communication, reducing data transmission errors by 90%.
• Distributed Control System Auxiliary Power: Supporting distributed I/O networks:
  • Chemical Plant Remote I/O Stations: Provides 24V DC to remote S800 I/O racks and sensor networks; wide temperature range (-25℃~+70℃) handles outdoor installation near process skids, while surge immunity (2kV) withstands lightning-induced transients.
  • Water Treatment Plant Instrumentation: Powers flow meters, level sensors, and valve positioners; low ripple output (≤100mVpp) ensures stable operation of sensitive measurement devices, maintaining accuracy of water quality monitoring.
• Manufacturing Automation Power: Supporting production line controls:
  • Automotive Assembly Line Sensors: Supplies 24V DC to photoelectric sensors and barcode scanners; compact design fits in tight machinery enclosures, while overload protection withstands current spikes from sensor startup.
  • Packaging Machinery Controls: Powers small actuators and encoder interfaces; fan-free design avoids contamination in food packaging environments, complying with hygienic standards (e.g., FDA 21 CFR Part 11).
• Critical Infrastructure & Mobile Applications: Reliable power in specialized environments:
  • Oil & Gas Offshore Platforms: Powers corrosion-resistant sensors and remote I/O modules; wide humidity tolerance (5%~95% RH) withstands marine environments, while flame-retardant housing (UL 94 V0) reduces fire risk in hazardous areas.
  • Railway Signaling Systems: Provides 24V DC to trackside sensors and control modules; vibration resistance (1g) withstands train-induced shocks, ensuring reliable signaling operation and passenger safety
