  • The NCS37010 is a fully UL943 compliant signal processor for GFCI applications with self test and lockout. The device integrates a flexible power supply (including both shunt and LDO regulators), differential fault, and grounded-neutral detection circuits. Proprietary impedance measurement and signal processing techniques are used to minimize the number of external components and improve performance. The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters. At power up the NCS37010 performs a self test at 60ms and removes the lockout if the test passes. This self test consists of a differential, ground-neutral and solenoid test.
  • Features
  • Full self test and electronic lockout - Fully compliant with UL self test requirements and minimal BOM impact
  • Self syncing internal oscillator adjusts to AC mains frequency to guarantee full resolution on 50 and 60 Hz distribution systems - Compatible with global power AC power systems
  • Randomized testing sequence to noise sensitivity and potential interactions on the AC mains - Robust design
  • High SCR drive current (up to 5 mA) - Compatible with high Igt SCRs for improved noise immunity
