220v Amp/DAC on 240v UK supply...bad ?

[hendern88]

Hi there,

I'm getting the above which work off 220v not 240. Is it dangerous to run these from 240v or should I look to method of getting 220v.


Whats therefore the simplest way to convert 240v down to 220v.....

many thanks
Neil

Hi Neil,

Would not worry too much - our 220V is not always 220V anyway
Since all of the inside electronics are running on either 5V or 12V, its the transformer that'll take care of that.

If you're really not comfortable, replace the 220V transformer inside the unit with a 240V one.

Would it be wise to run these via some 240v to 220v adapter sockets....or is there no need to fear blowing/buring out the transformer.

thanks again
Neil

Neil,

I am afraid I am not familiar with the sockets you are talking about so I can't confirm or deny that.
If I remember correctly most transormers are rated 220-240V on their primaries anyway so I would not be worried.
Present tolerance is +/- 10% and most devices can easily cope with that.
Within the european union there's an agreement to gradually and transparantly standardize on 230V anyway (compromise between the UK and the main land ). This will have no significant influence for our 'every day devices' - ok, there'll be a slightly larger current flow which can slightly increase the amount of generated heat which in turn potentially influences the life span of the device but again, I would not dramatize this at all.

thanks mate,

The only real problems,given the variation in mains voltage at certain times of the day,has been with some Chinese imports,using 220V transformers,as part of valve PSU's,where the stepped up voltages to run the tubes has resulted in the rectifiers being run at or above their design tolerances.

I am not aware of anyone here or elsewhere reporting it as a problem with solid state gear.
