AC/DC Adapters: Volts & Amps

[MrLip]

Hello.

I live in Thailand where the electricity voltage is 220 volts.

I have 2 AC/DC adapters:

a) The adapter that came with my POD (which was purchased in thailand) Input: 230V 50Hz Output: 9VAC 1200mA

b) The one that came with my ART Tube MP (purchased in the USA) Input: 120VAC 60Hz Output: 9VAC 800mA

I will not be using both of these products at the same time.

The ART's listed power requirement is: "9 VAC @ 700ma (typ)"

So my question is: since I won't be using both at the same time, would it be OK to use my POD adapter for my ART Tube MP?

I ask this because it would be easier to use the POD adapter instead of having to pass my 120V ART adapter thru a transformer.

Same output voltage, different amperes; is it safe?

I don't see any problem. The higher amperage is just a rating for the transformer itself and the device that's drawing. Since it's a higher rating, it should work fine, the transformer isn't going to burst into flames or anything.

Righto Emeric.

You can always use a transformer that has more milliamps, but not one that supplies less then is needed.

I thought I'd just add a bit as to why it's OK.

The adapter can supply up to 1200mA (1.2A). The unit (POD or Art) will draw 700mA. As Long as the unit doesn't draw more than the power supply can handle you're OK. Just remeber that current is not pushed down the line (ie you're not forcing a 700mA unit to accept 1200mA), it is pulled (the unit takes only what it needs.)

Sorry to answer the question a third time.
