Title:
POWER CIRCUIT
Document Type and Number:
Japanese Patent JPS54134347
Kind Code:
A
Abstract:
PURPOSE: To economically form two power circuits consisting of the input terminal, power switch, and noise filter which are commonly used for both the low voltage power supply and the high voltage power supply.
CONSTITUTION: The voltage detection circuit 27 detects that the power voltage is 100 V or 200 V. When it is 200 V, the switch element 28 turns ON and alternate current relay R is energized. Connection and switching of the primary 100 V and 200 V terminals of the transformer 7 and one power wire by the contact r of the relay R. Since swtiching is automatically performed, the user need not be careful of handling. The two power circuits with the same specification can also be manufactured.
