Abstract
PURPOSE: To enable to automatically select power supply voltage depending on AC voltage and to enable to supply to attenuation current sufficiently required for the demagnetizing coil.
CONSTITUTION: Be selecting the Zener voltage of the Zener diode 96 at a higher value than the low voltage division voltage, this Zener voltage diode 96 is conductive only when the AC power supply voltage is higher, and it causes the transistor 97 to be conductive, but when the AC power supply voltage is low, it is non- conductive. Thus, the transistor 98 is non-conductive when it is high and conductive, when it is low conversely. Immediately after the power supply switch 2 is applied, the B side of the contact 9b of the relay is closed and the relay is selected to the contact A side when it is operated. Since the current flowing to the demagnetizing coil 8 flows to the positive characteristics thermistor 5b immediately after the application of the switch 2 and flows to the positive characteristics thermistor 5a immediately with selection, the attenuating current in time aging can flow.
