Functional Features:
- Input Over/Under-Voltage Protection: Module protects and shuts down DC output when input voltage exceeds safe limits; auto-recovers when voltage returns to normal range
- Output Over-Voltage Protection: Shuts down output when voltage exceeds 325±5 VDC; requires power cycle to reset
- Output Under-Voltage Alarm: Triggers alarm when output drops below 198±1 VDC; auto-recovers when voltage restores
- Short-Circuit Current Foldback: Output current reduces to no more than 40% of rated current during short circuit; auto-recovers when fault clears
- Phase Loss Protection: Limits power output to half-load capability when input phase loss is detected
- Over-Temperature Protection: Shuts down when internal temperature exceeds 80°C; auto-recovers at 60°C
- Primary Over-Current Protection: Protects against rectifier-side over-current; requires power cycle to reset
- Fan Temperature Control: Three-speed fan control (off, half, full) based on combined temperature and current monitoring
- Fault Code Display: LED display shows fault codes for rapid troubleshooting
- RS485 Communication: Communicates with host monitoring system for remote voltage/current readback, alarm reporting, and command execution
- Hot-Swappable: Supports online module replacement without system shutdown
Application Scenarios:
- 35 kV to 330 kV substation DC power systems
- Power plant auxiliary DC supply
- Hydroelectric station control power
- Petrochemical facility emergency DC power
