Overview
Self Test Ground Fault Circuit Interrupter (GFCI) NCS37015 The NCS37015 is a UL943 compliant signal processor for GFCI applications with self test.
The device integrates a flexible power supply (including a 12 V shunt and two 3.
3 V internal series regulators), differential fault, and grounded−neutral detection circuits.
Self test is monitored at start up and then every 17 minutes.
Features • Meets UL943 Self−test GFCI Requirements • 4.
0 – 12 Volt Operation (120−480 V AC mains with the appropriate series impedance) • −40°C to 95°C • Typical 575 mA Quiescent Current @ 11 V • 16 Pin QFN • Inverted and Latched SCR Output to Facilitate a Solenoid Operation • Self Syncing Internal Oscillator adjusts to AC Mains Frequency to Guarantee Full Resolution on 60 Hz Distribution Systems • Optimized Solenoid Deployment (coil is not energized near the AC mains zero crossings) • Power Supply Monitor that Verifies Full Diode Bridge Operation • Tiered Trip Times that Increase Immunity to Noise • Under−vo...
