ABB 3BHE035301R1002 Power Supply Module

• Shock Resistance: 15g acceleration, 11ms duration (half-sine wave, IEC 60068-2-27)
• Dimensions (W×H×D): 48mm × 177mm × 130mm (fits standard 19-inch racks)
• Weight: Approximately 0.8kg
• Mounting Method: DIN rail mounting (EN 50022 standard) or rack mounting via adapter
• Protection Features: Overvoltage protection (28V DC cutoff), overcurrent protection (12A trip), overtemperature protection (85°C thermal shutdown)
• Certifications: IEC 61010-1 (safety), IEC 61000-6-2/6-4 (EMC), UL 508 (industrial control equipment), CSA C22.2 No. 14 (Canada)
• Compatibility: Symphony Plus DCS, AC 800M controllers, S800 I/O modules

Functional Features

• Redundant Operation Support: Enables parallel redundant configuration (up to 4 modules) with automatic load sharing, ensuring 99.999% power supply availability for mission-critical processes.
• Stable Output Regulation: Maintains ±1% voltage accuracy across full load range and input voltage fluctuations, preventing voltage instability from disrupting sensitive I/O and control modules.
• Comprehensive Fault Protection: Overvoltage, overcurrent, and overtemperature protections trigger fast shutdown or current limiting to avoid damage to the module and connected equipment; fault status is indicated via LED for quick troubleshooting.
• Low Ripple and Noise: Minimizes electrical interference (≤50mV ripple) to ensure stable operation of analog I/O modules and communication interfaces, critical for high-precision measurement and control.
• Wide Environmental Adaptability: Withstands extreme temperatures, high humidity, and industrial vibration/shock, suitable for harsh sites such as power plants, refineries, and chemical facilities.
• Easy Integration and Maintenance: Compact DIN/rack mounting design saves cabinet space; hot-swappable capability (when redundant) allows module replacement without system shutdown, reducing downtime.
• Status Monitoring: Front-panel LEDs indicate input power presence (green), output normal (green), and fault (red), enabling on-site personnel to quickly identify operational status.

Application Scenarios

• Power Generation Industry: Used in coal-fired, gas-fired, and nuclear power plants to power Symphony Plus DCS components (e.g., boiler control I/O modules, turbine protection controllers) and ensure continuous operation of power generation processes.
• Oil and Gas Industry: Deployed in onshore/offshore oil refineries, natural gas processing plants, and pipelines to supply stable power to emergency shutdown (ESD) systems, flow control modules, and gas detection equipment—complying with SIL 2 safety requirements.
• Chemical and Petrochemical Industry: Supports DCS and PLC systems in chemical reactors, distillation columns, and storage tank farms, powering temperature/pressure measurement modules and valve control actuators to maintain process stability.
• Metallurgical Industry: Applied in steel mills and aluminum smelters to provide power for automation systems controlling blast furnaces, rolling mills, and material handling equipment, withstanding high-temperature and dusty environments.
• Water and Wastewater Treatment: Supplies power to process control systems in water treatment plants, including pH sensor modules, pump control I/O, and disinfection system controllers, ensuring reliable operation of water purification processes.
• Industrial Manufacturing: Integrated into automated production lines (e.g., automobile assembly, semiconductor manufacturing) to power S800 I/O modules and machine vision systems, maintaining consistent power for precision control.
