8 amp pwer supply for a fridge.

I'll be in there tomorrow. I have the 5amp mobitronics one for the 30l waeco but it gets bit warm when running the 45L explorer on a hot day so an 8amp bump with fan is a good deal for that price.

I was recently looking for a power supply, the small variable voltage thingys (to power the GPS while @ home) and I saw one model that was rated at 5amp or some thing! Yeah right 5 amp @ 3volts. Marketing bullshot :( It was only good for 1 amp @ 12volt).
Is your 8amp rated for 12volt, is it 12volt only or variable.
It sounds good though, it's fan cooled too!
Very small? like a pack of matches? smokes? 240l wheelie bin?

I'm with you jimbo,went down today and brought two one for me one for the old man. You dont know until you give it a go.

Jimbo,

Jimbo,
Sorry, bloody laptop mouse pads.
The power supply is a switchmode power supply. These have been around for a few years now and dont have the old heavy transformers. In my work we would use 12 volt power supplies rated 15 amp that were bigger than a shoe box and took two hands to lift them. The 15 amp switchmodes fit in your hand. Switchmode means its electronic instead of electrical, and if you remember the old ceiling fan controllers compared to the new ones, its the same principle. They are very reliable, but just give them ventilation because if you dont it will blow if its got a heavy load and possibly double or triple the output voltage which wont help the fridge.

Jimbo , what was/is wrong with the mobitronics power supply as per Waeco , for the 80lt the mobitronic mps50 --- ac input 100-240vac 50/60hz 3a
dc output 27vdc 6a 150w
dc battery input 12/24vdc 12a/6a
dc battery otput 12/24vdc 12a/6a

Jimbo ,too bloody expensive !!!! ?????? $99 brand spanking new from the fridge shop ,,ours was free when we bought the 80lt .

Jimbo,
The switchmodes are pretty reliable, but would unplug it during a storm.The ratings on good quality supplies are the true constant load rating, ie they can handle full 8 amps continuosly and can go to something like 150-200% for a short while. The one you have may only be rated at 5amps continuos. I just noted you state the supply is 8amp 65 watt. 65 Watts is 5.5amps. 8amps is 96 watts. ( power = current x volts ).
We use industrial high grade power supplies at work. A top of the line true 8 amp continuos load supply from the is around $170. Check out the powerbox web site as they have hundreds of supplies.

does this thing do the job of say, a Thumper (Fridge shop) but in a much smaller package? Went into supercheap today and the bloke didn't know what I was on about. Nor did I, come to think of it. I merely asked for a 8 amp power supply @$70 told him it was approx fag packet size. Presumably their own brand?

aaaaah. Like the aforementioned mobitronics gizmo? Think you can get those in Big W for $50. Could be wrong. Will check.
