M54128FP Overview
The M54128 is a semiconductor integrated circuit designed for high-speed type earth leakage breakers. This lC includes leakage and abnormal voltage detecting functions. (TOP VIEW) GND 1 14 VS 13 VCC.
M54128FP Key Features
- Adopt the two times counting system
- lmprovement of ability against needless action due to lightningimpulse. q lt is a possible that cope with lEC owing to m
- Adopt the 1.5 times counting system. q High input impedance
- Filter circuit can be formed with externally attached C/R
- lmprovement of ability against needless action due to high frequency and high harmonics. q High input sensitivity : VT =
