Description

Core Technical Parameters1. Power Supply and Output ParametersInput Voltage Range:AC Input: 100V~240V AC, 50/60Hz (wide voltage adaptation, compatible with power grids in different regions);DC Input (optional): 110V~300V DC (supports DC backup power access in certain scenarios).Output Voltage and Current:Main Output: 5V DC / 20A (powers digital circuits and logic chips within the rack);Auxiliary Output: 24V DC / 5A (powers external low-power devices such as sensors and relays);Output Voltage Accuracy: ±2% (ensures stable power supply to devices at full load, preventing logic errors caused by voltage fluctuations).Redundancy Function: Supports parallel redundancy operation with 2 modules; when one module fails, the other automatically switches and takes the full load, with a switching time ≤10ms (no power interruption, ensuring continuous system operation).

2. Electrical Protection and ReliabilityProtection Mechanisms:Overvoltage Protection (OVP): Automatically shuts off when the output voltage exceeds 120% of the rated value to prevent damage to downstream equipment;Overcurrent Protection (OCP): Limits current when the output current exceeds 110% of the rated value to prevent module damage due to short circuits;Overtemperature Protection (OTP): The module automatically derates when internal temperature exceeds 85°C and resumes normal operation when the temperature drops below 60°C.

3. Communication and MonitoringStatus Monitoring Interface: Communicates with the controller via the Symphony Plus system backplane bus, uploading module status in real time (such as input voltage, output current, internal temperature, fault codes);Fault Alarm Output: Equipped with one dry contact alarm output (NC/NO optional), which triggers external audible and visual alarms when a module fault occurs, allowing maintenance personnel to quickly identify issues;Indicator Lights Feedback: The front panel has three LED indicators, showing “Power Normal (Green)”, “Redundancy Status (Yellow)”, and “Fault (Red)”, providing an intuitive view of the module’s operating status.

Features:1. High Redundancy and Reliability: Dual-module parallel redundancy design with seamless switching, suitable for critical control scenarios such as petrochemical and power industries where downtime is not permitted.2. Wide Input Compatibility: Supports 100V~240V AC wide voltage input without the need for additional transformers, suitable for power grids in different regions worldwide.3. Hot-Swap Design: Modules support live insertion and removal, allowing faulty modules to be replaced without stopping the entire DCS system, reducing maintenance downtime.4. Comprehensive Status Monitoring: Detailed operational data is transmitted via the bus, combined with indicator lights and dry-contact alarms, enabling visualized operation and maintenance, reducing the difficulty of troubleshooting.5. Industrial-Grade Durability: Uses high-temperature-resistant capacitors and shockproof housing, meeting the reliability requirements for long-term continuous operation in industrial environments.
