Abstract

PURPOSE: To reduce cost and enhance reliability by providing a control-power source by the use of an input power supply and by comparing and sensing voltages with a single power source.
CONSTITUTION: A resistor 20 is connected between an input terminal 9 and a resistor 8, and a resistor 21 is connected between the midpoint of the resistor 8 and 20 and a negative-side bus line 2. An anode A of a diode 22 is connected between the power-supply terminal 9 and the resistor 20. A resistor 23 is connected between a cathode K and a positive-side bus line 1A, and a capacitor 24 is connected between the cathode K and the negative-side bus line 2.
