What does the Alternating current symbol mean on chargers and power adapters?
On power adapters, chargers and electronic devices the wave marks the mains (AC) input rating, for example 100-240 V with this symbol and 50/60 Hz. A range like that means the adapter accepts any mains voltage within it. The output side that feeds the device is marked with the direct current symbol instead.
Does the Alternating current symbol mean the same on every appliance?
No. On IEC 60417 it means: Alternating current supply. On chargers and power adapters it means: Mains AC input on adapters and electronics.
What does the Alternating current symbol look like?
Single sine wave (tilde). It is also called “AC symbol”, “V~”, “tilde” and “~ symbol”.
Which standard defines the Alternating current symbol?
