Comprehensive Electrical Safety & Protection
• Smart Over/Under Voltage Protection: Automatically trips when voltage exceeds 275V or drops below 160V to prevent equipment burnout.
• Multi-Fault Detection: Beyond voltage, it protects against leakage, phase loss, power failure, overcurrent, and overload.
• Adjustable Leakage Sensitivity: Users can switch between four levels (30mA, 100mA, 300mA, and 500mA) to match specific environment safety needs.
• Phase Loss Protection: Specifically monitors three-phase systems to prevent motor damage or system failure when one phase goes missing 30V.
Advanced Intelligent Auto-Reclose Logic
•Fault-Specific Reclosing: It uses separate logic for current faults (SRM) and leakage faults (SRD), ensuring the reclosing strategy fits the nature of the trip.
•Intelligent Voltage Recovery: Once voltage returns to a safe range (e.g., 195V–255V), the system can perform an automatic reset.
•Customizable Sequences: It offers multiple preset modes (like RM1-RM8 or RD1-RD11) where you can define the number of retries and the wait time between them.
•Unmanned Efficiency: The system automatically restores power after a temporary fault is cleared, significantly reducing manual maintenance costs for remote sites.
Smart Connectivity & Control
•Standardized Communication: Uses the Modbus RS485 protocol, allowing the device to integrate quickly and accurately into existing monitoring platforms.
• Remote & Digital Control: Supports remote switching via software or physical digital inputs (DI1/DI2) for flexible integration with external hardware.
• Scheduled Operation: Includes a timer control feature for programmed power management.
Data Management & Hardware Reliability
•Visual Monitoring: The LCD screen provides a real-time display of voltage, leakage current, and trip counts for different fault types.
•Detailed Event Logging: Stores up to 20 alarm records with precise time stamps, making it easy to analyze the history of the power line.
•Energy-Independent Memory: A built-in supercapacitor ensures that all critical data is saved even if the power is cut suddenly.
•Compact Industrial Design: Features a space-saving DIN rail mounting system (4P width for 2P models, 6P width for 4P models).
Smart Feedback & Safety Security
• Advanced Safety:
Includes a triple-mode toggle switch (Auto, Manual, Lock) and a physical safety lock jack to prevent accidental remote power-on during maintenance.
• Optional Aux Status Output:
Provides real-time ON/OFF status feedback through a dedicated signal output port, allowing remote monitoring systems to confirm device execution.
