Description

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.
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
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
