装置の電源供給回路。 A power supply circuit for a large display device that has a set coil and a reset coil is used in a power supply circuit for a large display device that connects power to the preheat circuit and timer when a changeover switch is turned on, and to the display tube circuit when the timer operates after a predetermined period of time. The ON operation of the changeover switch connects the set coil, and the disconnection operation connects the reset coil.
It has an electromagnetic relay that is turned on by excitation of a set coil and turned off by excitation of a reset coil, a timer motor, and a clutch coil. and a timer that turns on after the motor has been energized for a predetermined time and turns off when the clutch coil is energized;
A power supply circuit for a large display device, characterized in that a power supply is connected to the display tube circuit in response to turning on of the timer.
