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.
