LINEAR INTEGRATED CIRCUIT
EARTH LEAKAGE CURRENT DETECTOR
DESCRIPTION
The UTC M54133 is a semiconductor integrated circuit developed for use in high-speed earth leakage breakers incorporating functions to protect against voltage surges and inverter noise.
FEATURES
* Improvement of ability against unwanted tripping by lightning-surge and lightning impulse. Two times counting system adopted. * Improvement of ability against unwanted tripping by inverter-noise. Built-in operational amplifier (of low current dissipation) for active low-pass filter. Improved high-frequency, high harmonic superposition performance * Internal time delay function * An external capacitor is used to set the delay time. * High input sensitivity: VT=11.5mVrms Typ. * Low-current dissipation (at RIREF=180kΩ) In stand-by condition: IS=610μA Typ. * High stabilities design Adopt the circuits that is not affected by fluctuations of supply voltage/ambient temperature.
