Overview
SL7101 EARTH LEAKAGE CURRENT DETECTOR Description The SL7101 is designed for use in earth leakage circuit interrupters for operation directly of the AC Line in breakers.
It contains pre regulator, main regulator, after regulator, differential amplifier, level comparator, 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.
