Overview
NCS37005 Product Preview Ground Fault Interrupter (GFI) Description The NCS37005 is a signal processor for GFI applications.
The device integrates a flexible power supply (including both shunt and LDO regulators), and differential fault detection circuits.
The proprietary fault processing circuitry offers high performance with low turns ratio ferrite current transformers.
The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters.
