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.
