Abstract
A power supply for a photomultiplier is provided, the power supply including: a charge pump configured to generate a first high voltage for the photomultiplier; a DC/DC converter configured to generate a second high voltage for the charge pump; a first control loop configured to control the charge pump and/or the DC/DC converter, the first control loop being controlled by the first high voltage; and a second control circuit configured to control the DC/DC converter, the second control circuit being controlled by the second high voltage. A radiometric measuring device for measuring a filling level and/or a limit level of a product in a container is also provided. A method of supplying power to the photomultiplier is also provided.
