What is this? Caravan/4x4 related

Fez_uk · 21-09-2013, 13:46

Anyone know what this is?

Something overland/caravan/4x4 related I think?

Caravan hookup? Small 3 phase inverter?

R1cho · 21-09-2013, 13:53

looks like a 3phase inverter to me

Terranosaurus · 21-09-2013, 14:00

Its a 12v DC power supply/transformer - it says as much on the label

Primary 240v

Secondary 0v / 12v

Edit...
12V DC.. Oh its plenty powerful enough

Fez_uk · 21-09-2013, 14:43

my thinking it's for caravanning?

& Hook up to it? Don't know what the mains plug is for if used on a site

More for when your caravan is used at home I was thinking?

Normally that type of enclosure is made for industrial use, to give 110 V ac from 240 volt mains, for operating low powerered power tools.

Now this looks like it is probably used as a 24 Volts ac supply for power tools, now caution, it is most likely ac, and if used to power a caravan will probably cause untold damage to anything connected to it, so don't be too hasty.

To be able to use it, you would need a bridge rectifier, and depending on the transformer,it may be possible to double up the output to give 20 amps.,
Caution, the winding outputs will need checking first before connection.

Also when the 12 Volts is rectified to DC, the peak voltage will be 1.4 times 12 volts, which is close to 17 Volts, whilst this could be used for battery charging, there would be no over charge protection, and if left for any time, could fry the battery.

If it was mine, I would have a look inside to see if there was a rectifier, then consider a rectifier, and voltage regulation to limit the voltage to 13.8 volts, but it would require quite a bit of re- work.
The rectifier and other components would be better placed in a well ventilated enclosure as there would be quite a bit of wasted heat.

BUT DON'T rush to connect it without checking the output.

Not going to connect it, Want to sell it. But ain't got a clue what it is

Probably not caravan, yellow box enclosure looks like building site electrics.

I tried entering the serial number/ JMSEN/ JMSENE into google - no luck. Any part numbers on it or internally?

The fact it has a CE number on it means it is a proper piece of kit (also has been PAT tested).

I have a 12v florescent down lighter lamp, we use in the awning of the caravan, which has a large 3d style bulb in it, more like you would find in a Mains lamp. The guy we got it from said they were used on tripods on building sides that were open to the elements, or in non-water tight tunnels, where water cold be running all around.

I think that he also had a couple of those boxes for running the lights, but as I wanted my light just for the caravan, I did not really look much closer at the box.

So I think it is for Hazardous area lighting.

RobN · 22-09-2013, 17:08

The yellow box generally signifies "Safe" for use on site, normally converts 240v to 115v, etc.

Lazy-Ferret · 22-09-2013, 17:10

Here it is I think...

Yes that looks the same type, as I suggested yesterday.
The 500VA could be worth quite a bit then.
There must be a manufacturers name plate on it, or it can't carry a CE certificate of conformity.

Fez_uk · 22-09-2013, 17:37

no manufacturers name on it, Looks very similar to linked item.

But it seems to be a 12v version?
