Switchmode power supplies offer several significant advantages over traditional linear transformer power supplies.They are far more efficient than their linear counterparts. As they do not use power or mains transformers the equivalent power supply weighs considerably less than traditional types. Physical size is also reduced. Though the power supplies are supplied in a vented steel cabinet they must be installed within a secondary earthed cabinet as the 240V input terminals are exposed.
