Abstract
The present invention relates to a supply voltage detection device (), in particular for at least one load, for monitoring a rectified mains voltage of a mains voltage supply () and for comparing a detected mains voltage value with a predetermined reference value, wherein, if the detected mains voltage value is lower than the reference value, switching to e.g. an emergency voltage of an emergency voltage supply can be effected by means of an electronic control system (). In addition, if a voltage limit value has been exceeded, the rectified mains voltage can be fed to an optocoupler () and a signal can be transmitted by said optocoupler for the duration of this excess, a duty factor that is dependent on the mains voltage value being determinable from the duration and the period of said signal.
