DC Arc Fault Detector
The Arc Fault Detector is designed for real-time detection of arc faults in DC circuits. Upon detecting an arc fault, it promptly sends an alarm signal to alert the inverter or other actuators, enabling immediate disconnection of the faulty circuit and effectively preventing fire hazards.
Main Functionalities
- Independent arc detection for each channel.
- Long string circuit support.
- Support module cascade connection.
- Modbus interface.
Advantages
Offers real-time arc fault detection, immediate alarm signaling and circuit disconnection to prevent fires and other damages in the PV system components. Each module supports up to 4 channels for integrated current measurement and can be cascaded with up to 8 modules, providing a total of 32 channels for comprehensive monitoring.
Advanced Arc Detection
Each channel features independent arc detection for precise monitoring. Set custom arc alarm thresholds to ensure safety and prevent false alarms.
Comprehensive Measurement
Integrated current measurement provides valuable data for system optimization. Monitor and analyze the performance of each channel with detailed measurements.
Enhanced Compatibility
Long string circuit support up to 1600m accommodates larger installations. Compliant with SunSpec Standard RSD and UL1699B (Type 1) for reliable and easy installation.
Standard Communication
Modbus interface with standard protocol ensures seamless integration with existing systems. Clearly identify faulty arc channels for quick troubleshooting and maintenance.
Scalable Modularity
Each module supports 4 channels, offering flexibility in system configuration. Easily expand your system by adding more modules as your needs grow.
High Expandability
Support up to 6 cascaded modules, expanding the system to 24 channels. Scale your PV system without compromising on performance or safety.
