Description
The UTC M54134 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
- S.
- 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 Ty.
