GROUND FAULT INTERRUPTER EARTH
LEAKAGE CURRENT DETECTOR
KK54123
Description
The KK54123N/D is designed for use in earth leakage circuit interrupters for
operation directly off the AC Line in breakers.
It contains pre regulator, main regulator, after regulator, differential
amplifier, level comparator, latch circuit. The input in the differential amp
latch circuit. The input in the differential amplifier is connect to the
secondary node of zero current transformer.
The level comparator generates high level when earth leakage current is
greater than some level.
