ACDCs

ACDCs is a term used in electronics to refer to devices that can accept both AC and DC power, and in popular culture as a reference to the Australian rock band AC/DC. The two uses are unrelated but share the same abbreviations.

In electronics, AC/DC devices are designed to convert and regulate incoming power to stable DC rails. They may include rectifiers, filters, and regulators; many consumer adapters advertise "AC/DC" or "universal input" capability, accepting standard mains voltages (for example, 100–240V AC) and sometimes DC input such as battery sources. The design emphasizes safety, isolation, and efficiency.

In music, the band AC/DC formed in Sydney in 1973 by brothers Malcolm and Angus Young. Original vocalist Bon Scott contributed until his death in 1980, after which Brian Johnson joined. The group's high-energy guitar-driven hard rock became widely influential. Notable albums include Highway to Hell (1979) and Back in Black (1980), the latter becoming one of the best-selling albums of all time. The band's lineups have evolved, and their music remains a staple of rock radio and live performance playlists.

The term AC/DC is typically used with a slash in branding; references to it without the slash or in plural form are common in informal writing. The two contexts—electrical engineering and rock music—are distinct but share the same abbreviation.
