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 = 6.5mVrms
5.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 supply
voltage/ambient temperature are small
