M54133数据手册UTC中文资料规格书

描述 Description

The UTC M54133 is a semiconductor integrated circuitdeveloped for use in high-speed earth leakage breakersincorporating functions to protect against voltage surges andinverter noise.

特性 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.
