常见问题

What is the difference between AFCI and GFCI signal processors?

AFCI processors detect high-frequency noise patterns characteristic of electrical arcs, while GFCI processors monitor current imbalance between hot and neutral lines indicating ground faults.

Can signal processor ICs be used in both residential and industrial applications?

Yes, but industrial versions typically have wider temperature ranges, higher noise immunity, and enhanced diagnostic capabilities compared to residential variants.
