DescriptionGround Fault Interrupters, Earth Leakage Current Detector IL54123N,D,S
The IL54123N/D is designed for use in earth leakage circuit interrupters for operation directly off the AC Line in breakers.
It contains pre regulator of the IL54123, 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 of the IL54123 generates high level when earth leakage current is greater than some level.
