SM73201-ARC-EV: Arc Detect System for Solar Panels

The SolarMagic™ reference design kit RD-195 includes the SM73201-ARC-EV PCB which is a UL1699B compliant Photo-Voltaic Arc Detect System with a minimal footprint of less than 50mm x 30mm. The reference design utilizes National Semiconductor’s advanced Analog technology along with an innovative dynamic filtering technique to effectively detect the signature of Arcing conductors in the presence of highly noisy real world environments.

Implemented with National Semiconductor’s PowerWise® technology, the Analog path requires less than 50mW of power to implement the active filtering. The operation range of the device covers the industrial temperature range of -40°C to +125°C. SolarMagic™ technology is an overall solution that works in existing and new installations, residential, commercial, and utility scale projects.
