ARCTRANS-100A arc conversion and protection

ARCTRANS-100A uses the pre-circuit to convert and amplify the signals of four arc sensors, and the signal conversion adopts the special ARCEYE-100C dual-sensor integrated photoelectric device, which can linearly convert the incident signal from 0 to 0~50kLux. The threshold judging circuit includes threshold setting and logic conversion. If any arc signal exceeds the threshold, an action signal will be output.


1. Technical characteristics

● Adopts pure analog circuits, featuring fast response and excellent anti-interference performance. The arc light identification and response time is less than 2ms.

● Equipped with a wide-angle point-type passive arc light probe: visible light/ultraviolet light, with a photosensitive angle of 360°×240°.

● Full fiber opticization of arc light signal input and output, ensuring strong anti-interference capability.

● Abundant protection outputs: conventional relay action signals, fast optical pulse action signals, and LED color-change indication.

● One-key reset design for arc protection signals.
