230v

230v

I believe the product standard used to be a lot higher. Off load I thought it was about 270V.
If someone has an older model it could be suppling more than 230V.

Edit - there was a thread here three years ago with some of the details. My post #25 refers.

The pictogram is defined in the standard, so I assume putting it on the outlet is a prerequisite for compliance.
You've made me think, perhaps the issue is all about too little load.
The standard allows a no-load transformer voltage of 275V
Maybe the issue is, with a 1W toothbrush charger, the voltage could be higher than the charger is rated for?

Agreed, 'Off Load' the Output Voltage could be higher than the 'Nominal 230v' expected.
I recall investigating a supposedly faulty unit and recording 246v but under load that would drop back a bit to within specified limits?
I don't have a copy of the product standard but there would also be a tolerance (+/-) on the output.

With a transformer.

Neither the rated supply voltage nor rated output voltage of a shaver supply may exceed 250 V AC The no-load output voltage is not to exceed 275 V and the difference between the no-load output voltage and the output voltage under load shall not exceed 20 % of the load output voltage.

There it is in B&W cant argue with that ....... thanks mainline, hope that answers the OP's query!
