KK7101

KK7101 GROUND FAULT INTERRUPTER EARTH LEAKAGE CURRENT DETECTOR Description The KK7101N/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. KK7101 Feature Low Power Consumption (PD=5mW) 100V/200V 100V/200V Common Built-in Voltage Regulator High Gain Differential Amplifier High Input Sensitivity Minimum External Parts Large Surge Margin Wide Operating Temperature Range (TА= -40 to 85°C) High Noise Immunity Meet U.
