I want to set up a transformer to allow me to switch the 12v Travel Buddy oven to be used on 240v when available. Would the following item be suitable, or does anyone have other suggestions (he says... holding his head, awaiting the barrage)?

Should be fine but a lot of extra work to make it safe to handle plus its somewhat overkill.

However the oven only draws 6-10 amps (depending on the model.)
I'd rather see you buy a supply already in a finger proof case.
Something along the lines of the 10 amp model here-

Thanks Malcolm. I looked at these. The unit draws around 10 amps. To create a better connection I could cut the plug off the 12v end and wire into a switch, yes?

I'd like to make this a permanently wired install (the oven manufacturer recommends doing this for the 12v for the oven anyway).

Cheers,

Mark

Hard to say without seeing what you are doing.
Presumably the 240v is just for caravan parks etc. I'd be leaving the adapter as a separate converter and just plug it it when needed 240v but I don't know how your truck is set up.

I have a battery charger which also has a dedicated 12v power supply maybe an option with a battery charger thrown in

Didn't think of that.

Hi Mark, first missile of the "barrage"...............

The product you instanced does not meet the Australianelectrical safety requirements. It is an offence to offer appliances for sale in Australia that do not meet these requirements.
It is clearly a power supply designed for mounting within computer or similar equipment and from a search I see that it comes from a large batch (1000 plus) of offered surplus manufacturing stock.

That is not to say that it would not serve your needs, but it has obvious safety inadequacies....... The 230v cable is not adequately secured and the 230v terminals are not adequately shielded against personal contact. Further, the 12v 'cigar socket' is certainly not capable of handling the rated 30A output, 10A at most. Even if you purchased this product you would need to attend to these matters.

Cheers
Allan

Thanks Alan, quite obvious that this isn't my area, eh?

Love the word "barrage"! It sounds so dramatic. One of my favourite quotes...

"A relentless barrage of ‘why’s’ is the best way to prepare your mind to pierce the clouded veil of thinking caused by the status quo. "

Probably more than a few on here will recognise it.

Cheers,

Mark

Don't get me wrong Mark, the product you were interested in would likely serve your needs. But if you use it, be sure to anchor the mains cord over its outer sheath and arrange a well-fixed cover over the terminals..... wouldn't want one of your loved-ones getting electrocuted, would we?

Cheers

My suggestion would be to get an old power supply from a computer and use that.

Have a look at this article here

I would also advise replace the ciggy plug and socket and using the Anderson connectors especially at 10A.

I run my modem/router and NAS drive from one of these when at home, in the van it just plugs into the 12V battery.

Well yes, there has been one such on my bench for some time.

But you better have some electrical skill before trying to modify one.

Have you tried a portable car fridge transformer? I have a Waeco fridge that comes with a transformer which is very handy for running a multitude of things that have cig plugs on 240v.

I love my Travel Buddy fridge one of the best purchases I've made for the back of the Troopy!
