DESCRIPTIONS
The IP911 is a semiconductor integrated circuit with
amplifier for a high-speed earth leakage circuit breaker.
The IP911, an advanced ground fault interrupter,consists
of differential amplifier, internal time delay,latch circuit and precision
voltage reference.
It is connected to the secondary side of the zero current
transformer(ZCT) which detects leakage current in the both inputs of the
differential amplifier.
It drives a thyristor connected to the output terminal of
latch circuit.
The internally integrated high frequency noise filter can
eliminate the abnormal input noises.circuit.
