Detect specific wavelengths of ultraviolet light emitted from the arc! Outputs contact signals to the relay section.
The "S28-R1 type" is an arc detector for DC high-speed air circuit breakers. It is capable of providing contact output when an arc is detected. By using a combination of special filters and elements, it eliminates false operation from natural light. This product is designed to be used in combination with relays. 【Features】 ■ Detects ultraviolet rays of specific wavelengths emitted during an arc and provides contact output to the relay section. ■ By using multiple semiconductor light-receiving elements and arranging them at different angles, it expands the detection range. *For more details, please refer to the PDF materials or feel free to contact us.
