I bought Logitech R20 speakers in the UK - 240V and wish to use in the US -110V. Will the speakers work if conected to the lower voltage. Will the speakers be damaged if connected to 110V supply

You need a 110v to 240 volt converter
google search
110V to 240V Step Down Up Transformer Voltage Electricity Converter Adapter

or
go to a local apple store and purchase a 110v 12W USB power adapter designed for IPAD 6

DON"T PLUG a 110V usb power adapter into 240V as smoke will come out of it and it will stop working

Buy a voltage converter transformer.

Check the mains input voltage on the printer. If it is 110v then you need a step down transformer 240v to 110v.

No you cannot as 220v will damage the 110v the Logitech. You need a stepdown transformer to reduce the voltage from 220v to 110v. and then you can safely plug the Logitech into this stepdown transformer.

Hi,

9 beeps means that the input voltage to the PC's power supply is incorrect, have you changed the switch at the back of the PC from 110 to 240v or vice versa. If the PC was not bought in the UK then it may be set to 110v in which case the voltage selector at the back of the PC needs to be changed to 240v. If there is no voltage selector would recommend changing the power supply.

If by changing the selector to the correct voltage it still beeps 9 times you are looking at a new power supply unit which you can buy from HP at a high cost or buy a used one from:

Hope this helps!!!

I think that Sony Bravia are sold with dual voltage, 110V and 220V. All 220V devices work also on British 240V network.

If an electronic device is not compatible with the 240V/220V network, then the PSU must be replaced.

In your case the unit should be dual voltage, compatible with 220/240V networks. Just ensure checking the user manual, or the tag at the back of TV.
All you need in that case is an adapter that can be purchased at any local electrical shop (eg. Curry's if you are in UK).

Regards.

There are two systems in use in the states
110v dryers are available that fit a standard 11v 15a socket
110/220v fit the oversize 'dryer' sockets, and they are two 110v phases 90 degreees apart
the motor runs of a single phase 110v.
there is 220v between the 'outside', the active lines of the two phases, at any time, but it is not useable to provide mechanical power as a single service, due to the complicated shape of the wave form when you add out of phase voltages together, but is ok to drive the heaters, they have no mechanical efficiency requirement
A 2 phase 110v heater it means 3kw can be supplied without a 30 amp circuit
but it becomes difficult to use a single phase 220-240v transformer to provide 2x110v 90degree 2 phase current unless you specially buy one in. .
High power applications in 220-240v are generally supplied by 415v 3 phase 60deg supplies,

Any transformer would be onsellable at the end of your posting, to your replacement, who would doubtless be in the same boat as you, with a heap of 'stuff' that needs to run.

UK Aus NZ may be sources of transformers, or dryers to suit.
check with Australian UK NZ suppliers as well as local Indian ones, as those countries are also nominal 240v single phase home suplies and they may have (1) the dryer, or (2)the transformer to suit the 110 2 phase dryer

This trimmer is only made to be used with 110V, we do not have this model in 240V. There is no way to stop the noise. If you would like to purchase a unit made for 240V please call 1-800-558-9441 and speak with one of the Andis customer service reps.

Thank you for purchasing Andis.

Hi , you will have to open the box and check for any fuses along the power input line, replace them if any and try it out but i strongly believe what happened there is that you fried the power supply in your subwoofer , there is no easy fix to this , you will need to replace the transformer and possibly check to see if the rectification circuit is damaged too, and the amplifier too. Good luck
