An automatic exposure control device used to terminate the exposure after a desired exposure has been reached.
17. main circuit
Supplies the x-ray tube with properly modified power.
The alternating current is supplied to buildings; usually supplied in three phase power cycle, also called incoming -line current.
19. main switch
The switch that generates the power to the x-ray tube.
