FEATURES
q Improvement of ability against unwanted tripping by lightning -surge. Adopt the two times counting system. Improvement of ability against needless action for lightningimpulse. q Improvement of ability against unwanted tripping by inverter -noise. Built-in operational amplifier (of low current dissipation) for active low-pass filter. Improvement of ability against needless action for high frequency and high harmonics. q Built-in delay time function An external capacitor is used to set the delay time. q High input sensitivity : VT=11.5mVrms Typ. q Low-current dissipation (at RIREF=180kΩ) In stand-by condition : IS=610µA Typ. q High stabilities design Adopt the circuits that is not affected by fluctuations of supply voltage/ambient temperature.
