KA2803B
Earth Leakage Detector
Features Low Power Consumption PD =5mW, 100V/200V Built-in Voltage Regulator High Gain Differential Amplifier 0.4mA Output Current Pulse to Trigger SCR' S Low External Part Count DIP Package (8-DIP), High Packing Density High Noise Immunity, Large Surge Margin Super Temperature Characteristic of Input Sensitivity Wide Operating Temperature Range (TA = -25°C ~
+80°C) Operation from 12 to 20V Input
Functions Differential Amplifier Level Comparator Latch Circuit
DescriptionThe KA2803B is designed for use in earth leakage circuit
interrupters, for stable operation of the AC line in breakers.
The input of the differential amplifier is connected to the
secondary coil of ZCT(Zero Current Transformer). The
amplified output of differential amplifier is integrated at
external capacitor to gain adequate time delay that is
specified in KSC4613. The level comparator generates high
level when earth leakage current is greater than the fixed
level.
