SPN5689A((BlacK) : 220v electricity usage, do I need a transformer? Or, I just need only 220v plug?

It plugs into a regular US wall socket. I doubt it would plug into another socket. I would be concerned that any alternate voltage going into it might fry whatever you're trying to change. I wouldn't even use a transformer.

NO! DC only. You would need a rectifier on the output of your transformer or just a DC power supply fed from your normal 120 VAC .

The mains transformer (to supply power) is separate from the amp unit. It has two primary windings allowing you to connect for 115V (parallel) for US or 220V (for Europe, for example). You will also need to connect the secondary HV (amp HV) and LV (tube heaters). It's not rocket science but if you have no idea which end of a screwdriver is the business end, you may want to give this amp a miss. (I believe that I left notes on connecting up the transformer on Amazon when I first purchased this baby). Additional connections are input/output - they're pretty obvious.

Hi, You should buy a step down transformer 220 to 120 but first you should check how many watts the appliance uses. The transformer you buy should have at least 50% more wattage than your appliance uses to be able to handle spikes on the usage which normally happen when the appliance starts.

These style transformers are for use on single phase circuits. Your dryer being 220v may require a two phase circuit. This time I would consult a licensed electrician. It's not necessarily a big deal (meaning a costly thing) but if the heater requires 220v two phase power, then that's what it needs. Many of those house fires like we've seen all winter on TV news are caused by mismatching wiring and heaters. Please, be safe and call a licensed sparky! Kia ora. GW

I thought about laying down some Ohm's Law, and the (current squared x resistance) heat loss thing, sorry. Lets just say that devising a step-up transformer circuit would be impractical, expensive, and maybe illegal in most jurisdictions. Having a 220/240V - 20 amp receptacle Installed or buying a 110V unit are your only choices.

Noo. U need transformer. Don't get this item it's not new . It is used . Trust me. Get new 1. Do not get it from here. Ali

An adapter is definitely needed- the UK plugs are much bigger with a 3 prong configuration. Also, their voltage is 220 so you need more than just an adaptive plug. I purchased an appliance that had a switch from 110 to 220 which made it easier for travel--then carried different plug configurations for travel through Europe.

Because I try to use a 220 volt adapter.Can only if the adapter without transformer(110->220)?

Hi Karthik, according to the manual that came with it, the product switches voltage automatically, so the only thing you will need is an adapter, NOT a transformer.

It just depends what you are plugging into it. A laptop for example, has a big fat brick type thing that is in the power cable, one side goes to laptop, the other goes into outlet. If you read the fine print on this black brick thing, it will say, input 110v - 240v, 50-60hz. So for this example, you need no converter. Take any of your portable electrics, and it will have similar info on it. You want to make sure it says 110v-240v, 50-60hz input. If it just says 110v input, you need a converter.

No, it is a relatively heavy consumer of energy and therefore impractical to build in a transformer into it. you will need a fairly heavy standalone transformer to run it off a 220V outlet, like Goldsource ST-500. Not worth the trouble in my view.

It sounds like you will NOT need a transformer but just a plug adapter. The power supply of your item is capable of any input voltage from 100v to 230v, and 50 or 60Hz. The US uses 120v and 60Hz so it will work there. The only consideration now is if you have the right plug shape to plug into US wall sockets. I have moved between Canada/US [120v/60Hz] and Europe and Australia [230v/50Hz], so I have some experience with this. All of my electronics that are marked this way worked in these locations (TVs, laptops, most modern chargers). So you don't need an active transformer like this, you just need a simple physical plug adapter like this: http://www.amazon.com/Ceptics-Grounded-Universal-Plug-Adapter/dp/B0080SE6H2/ref=sr_1_13?ie=UTF8&qid=1413903131&sr=8-13&keywords=ceptics

I live in the UK and used a transformer for mine for a while and it worked great. Not wanting a big transformer in the living room floor I went to my local Roomba dealer and found a 220v power pack that worked great and been using ever since without problem. The power is stepped down before it plugs into the base station already so it just uses a different step down plug.

Thomas . . . Simply plug the AC cord into an outlet. The transformer is part of the unit. No external transformer is needed.

Yes you will need a transformer. It is a great unit. You will be glad that you purchased it.

The voltage rating is 110-230v so you won't need a transformer as long as the voltage for the country you're in falls within that range (most do).
