KA2803B  
Earth Leakage Detector  
Features  
Description  
• Low Power Consumption P =5mW, 100V/200V  
D
• 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  
The 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.  
• Wide Operating Temperature Range (T = -25°C ~  
A
+80°C)  
8-DIP  
• Operation from 12 to 20V Input
