PURPOSE:To display abnormality by means of a stabilized constant display signal without switching the display signal at the time of overcurrent. CONSTITUTION:A triggerable one-shot multivibrator 8 is triggered with an output from an overcurrent detecting circuit 3 at the time of overcurrent to produce a display signal of constant level for a predetermined interval. Consequently, a display means 9 can display abnormality for a predetermined interval. |
