    Product Details

    The ALS01 Arc Light Sensor consists of three main components: the Arc Detection Probe, the Transmission Cable, and the Photoelectric Converter (converter).

    The Arc Detection Probe receives the arc light generated during an arc fault event. Its coating filters out the visible light component of the arc light. The probe receives the ultraviolet (UV) light within the arc light and converts it into visible light.

    The Transmission Cable utilizes large-core diameter Polymer Optical Fiber (POF) to transmit the visible light converted and output by the arc probe to the photoelectric converter.

    The Photoelectric Converter performs photoelectric conversion on the optical signal received via the transmission cable. The resulting electrical signal is transmitted to the circuit breaker, enabling its control.

    The ALS01 Arc Light Sensor achieves microsecond-level arc light detection. Compared to other arc light sensors, the ALS01 offers superior arc light resolution and enhanced anti-interference capability against visible light. Communication between the Arc Detection Probe and the Photoelectric Converter employs optical fiber transmission, making it immune to electromagnetic interference (EMI). This allows the sensor to operate reliably in various high-voltage, high-current electromagnetic environments.
