FIELD: electricity.
SUBSTANCE: invention is attributed to the field of electric engineering. Essence of invention: secondary switched power supply comprises: voltage converter, microcontroller, two digital-analog converters, analog-digital converter, automatic brightness adjustment amplifier, key unit, voltage multipliers, interface. The device performs automatic adjustment of amplifiers output voltages depending on ambient temperature with simultaneous control of automatic brightness adjustment current and alteration of photocathode voltage generation mode depending on brightness level on the photocathode.
EFFECT: extension of electron-optical converter illumination dynamic range, control signals generation without using external circuits, decrease in device overall dimensions.
