Abstract
The present invention relates to a detection circuit for detecting that a power supply unit is connected to a wrong supply voltage. Said detection circuit comprises a first voltage divider () connected to the output terminals () of a rectifier () of the power supply unit, a second voltage divider () connected to a first power input terminal () of the power supply unit and to one of the output terminals () of the rectifier (), and a circuit breaker () connected to the first power input terminal () of the power supply unit and to an input terminal of the rectifier (), wherein at least one partial voltage of each voltage divider () is used a signal () for identifying the wrong supply voltage. The invention relates further to a method for detecting that a power supply unit is connected to a wrong supply voltage.
