IM IN LONDON. I PURCHASED AROMA RICE COOKER THROUGH AMAZON.120V RICE COOKER. How to use it here in London?


Look on the information label to see how many amps it draws at 120 volts. Multiply the amps by 120 to get watts. Next you'll need to get a transformer that will handle the watts when changing 240 volts to 120 volts

Led wiring diagram on 240V AC


Is Led 120V or 240V?
For 120V you need a neutral wire.
240V generally does not have neutral wire.

Hello,

I will accept the second option which is getting transformer.

Go ahead and get a transformer in order to step up the voltage. This is better than hooking up the 120V AC to the master inverter.

In summary, get a transformer to step up the voltage.

I hope this is clear now....

Good luck.

Hi. I have a charger for 18v Dewalt Li-Ion (dc9130 120v 60hz) and I'd like to find a circuit diagram so I might be able to convert it to use with 240v 50hz. So I probably need the diagram for the 240v one...


most chargers will fuction on 240/50 hz, look closely at the writing on the charger, it may say. I have laptop chargers and have used the overseas with no problem, that being said, you might try contacting dewalt and asking them if you can do it. Like I said, it probably already will work without doing anything. i have seen some devices (amplifiers mostly) that have a switch on the bakc to switch voltage, ( I don't recall ever seeing a switch to change line frequecny though), hope this helps a bit

Can a 240 volt outlet be ran off this breaker and can a 240 volt electric baseboard heater be wired to it or should i use double pole breaker?


You need 240 breaker:
Notice that your 240V breaker is twice as wide as regular 120V breaker.
Notice that both switches are tied together on 240V breaker, making this a double-pole breaker.

Can you put a aussie 240 volt plug on an US battery charger


Look at the specs on the label, if it says that the charger is capable of taking a 240v input then you can change the plug and use it at 240v with no problem. If it says 120v then you won't be able to, you'll want to use a transformer or some other 240 to 120v supply.

I have a ups system that i am feeding with 240 vac phase to phase and both phase to ground readings are 120 vac but when i go to battery power i get 240 vac phase to phase and 1 phase to ground i get 220...


No, I don't think there is anything wrong. Your UPS seems to have a single phase 240V output, which seems to be "floating" (no or only a weak ground reference).
Just be aware that you can only power 240V equipment from it. If you need 120V for some devices _and_ if the UPS provides sine wave output, you could use a step down transformer for this purpose.

Electrical how to make it to 120v.


The drive motors for the washer and dryer run off 120 VAC, but the heating circuits require 240 VAC in order to work. You will need to have a 240 VAC outlet installed in order for the appliance to run properly. There is no conversion for this. This is the way the appliance was made.

Dewalt charger


Ok, for easy way, you can just put a 1~2A diode in series of the input 240v power wire, so the after voltage would be around 120v, but for precaution it is better that you put two diode in series, it will give you same result. In addition, I have already tested it on a similar charger, it works fine.
p.s: I do have a similar one that is also 110v, I compared it with other 240v one. They worked same.
