The RD-195 reference design is a DC arc detection solution that reliably detects arcs and alerts the system, reducing the chances of fires being caused by arcing. The solution is fully programmable, providing maximum flexibility for system integration and false detection optimization. It is accompanied by an easy-to-use GUI, enabling rapid alteration of detection parameters for easy evaluation.
The RD-195 reference design kit includes the SM73201-ARC-EV PCB with a minimal footprint of less than 50 mm x 30 mm. The reference design utilizes a proprietary dynamic filtering technique to effectively detect the signature of arcing conductors in the presence of highly noisy real world environments. The analog path requires less than 50mW of power to implement the active filtering. The operating temperature range of all the devices cover the industrial temperature range of -40°C to +85°C.
For solar component manufacturers investing in the US market: The RD-195 reference solution is fully compliant with the NEC690.11 requirements.
