Providing dental X-rays needs a steady, high-voltage electrical supply to drive the X-ray tube. That power comes from the building’s electrical system and is delivered to the X-ray unit through a wall outlet. Inside the unit, transformers and rectifiers convert that mains power into the kilovolts and milliamperes required to generate X-rays. A battery pack might power some portable devices, but it can’t reliably supply the intense, continuous power needed for standard exposures. An on-site generator could supply power if mains aren’t available, but it isn’t the typical source for everyday dental radiography. Solar power, while possible as part of an overall system, ultimately feeds the same electrical grid through an inverter and storage, so the immediate power for the unit still comes from the wall outlet.
