The M54128 is a semiconductor integrated circuit designed for high-speed type earth leakage breakers. This lC includes leakage and abnormal voltage detecting functions.
Typical Application |
Features |
| Earth leakage breaker | 1.lmprovement of ability against unwanted tripping due to Iightning-surge. • Adopt the two times counting system. • lmprovement of ability against needless action due to lightningimpulse.2.lt is a possible that cope with lEC owing to mode change. • Adopt the 1.5 times counting system.3.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.4.High input sensitivity : VT = 6.5mVrms5.Abnormal voltage detecting (neutral conductor open-phase protection) function : • Neutral conductor open-phase protection at single-phase threewire system •ln case of no use this function, stop this function and reduction of circuit current, possible.6.Low voltage operation : 7 to12V (conventional Mitsubishi lCs : 12 to 20V)7.Low current dissipation : • In stand-by condition : 820mA typical (Vs = 9V, Ta = 25°C) • When SCR is ON : 740mA typical (Vs = 9V, Ta = 25°C)8.Highly stable design : Employment of circuits of which characteristics fluctuations resulting from changes in supplyvoltage/ambient temperature are small |
