Abstract: A plug-in power supply wherein the mains plug unit is exchangeable in the form of a conversion plug system. The plug-in power supply includes a housing having a voltage transformer module for converting a mains voltage into the required low voltage, and an exchangeable mains plug unit with at least two mains plug pins. The plug-in power supply includes an exchangeable mains plug unit, and the housing includes at least two spring contacts which are electrically connected to the voltage transformer module. The mains plug unit includes at least two contact pins which cooperate with the spring contacts so as to establish an electric contact with the mains plug pins, and each contact pin is arranged in a separate recess.
