The Arc Fault Detection Sensor is primarily used for real-time detection of arc faults in DC circuits. Upon detecting a fault arc, it immediately issues an alarm signal to notify the inverter or other actuators to disconnect the faulty circuit, effectively preventing fire hazards. Each module can support up to 4 channels simultaneously and allows for integrated current measurement. It supports module cascading, with a maximum of 8 cascaded modules, totaling 32 channels.

Main Features:

1. Modular design, each module supports 4 channels simultaneously
2. Integrated current measurement
3. Maximum current per channel: +20A
4. Alarm signal is an open-drain output, compatible with various alarm levels
5. Local data uploaded via RS485 bus, no external wiring or devices required
6. Complies with UL1699B (Type 1)
