AN-2154 RD-195 DC Arc Detection Evaluation Board
.....................................................................................................................................................
The RD-195 reference design 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 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 operation range of the device covers the industrial temperature range
of -40°C to +85°C.
