FIELD: electrical engineering.
SUBSTANCE: device contains a power source for the operation of an element for controlling a technological process in a system for controlling a technological process; and a stabilized power source. In case of interruptions in energy supply from the specified power source to the element for controlling a technological process, the stabilized power source supplies energy for a period of time that is less than interruption threshold time, thereby preventing a false start of a shutdown function of the specified element for controlling a technological process.
EFFECT: preventing interruptions in power supply to an element of a system for controlling a technological process caused by instability in energy supply from a power source.
