A wavy line (∼) — IEC 60417-5032, indicating on a rating plate that equipment is suitable for alternating current.
Also known as: AC symbol, IEC 60417-5032, Wavy line symbol
Used on a rating plate to indicate that the equipment is suitable for alternating current only, and to identify the relevant terminals. Conventionally printed next to the AC voltage rating.
Indicates on the rating plate that the equipment is suitable for alternating current only, and identifies the relevant terminals.
Contexts: Electrical equipment
Is a single sine wave, defined in the IEC's graphical symbols for use on equipment, and marks a terminal, a supply or a rating as alternating current. On a power adaptor it labels the mains side; on a multimeter it selects the alternating range.
Contexts: Electrical equipment
Appears beside its direct-current counterpart on nearly every mains adaptor, and the pair is the fastest way to read what a power supply does: alternating in, direct out.
Contexts: Electrical equipment
A single horizontal wavy line, curving up then down like a flattened letter S on its side.
The pair used on rating plates and power supplies to distinguish which kind of current a terminal expects.
