Certain examples described herein relate to a removable unit of an additive manufacturing system. The removable unit is connectable to a base unit. When connected and operational, the base unit supplies a first voltage to the removable unit via a first power coupling. The removable unit has a power supply unit that converts the first voltage to a second voltage. The second voltage may power a number of low voltage components. The removable unit also has a power multiplexer. When the first voltage is unavailable the removable unit switches the power multiplexer to use a second voltage that is supplied from the base unit via a second power coupling.
