KA2803 detector equivalent, earth leakage detector.
* Low Power Consumption: 5 mW, 100 V/200 V
* Built-in Voltage Regulator
* High-gain Differential Amplifier
* 0.4 mA Output Current Pulse to Trigger SCRs <.
The KA2803 is designed for use in earth leakage circuit interrupters,
for operation directly off the AC line in breakers. The input of the differential amplifier is connected to the secondary coil of Zero Current Transformer (ZCT). The amplified outp.
