Structure, W orking Principle and Technical Parameters

1. Structure and working principle
The structure of this unit is simple, mainly composed of the x-ray device, charger and bracket.

Working principle

The internal power of the device, after converted by the control wiring, is in one circuit sent to a boost device to generate a high voltage supplied
 to the anode of the x-ray tube, and in the other circuit, filament voltage is formed and supplied to the cathode of the x-ray tube. In this way, the x-ray
is generated.
