Hi All, can anyone tell me which model engels will run on 24v and 12v, the old green lidded models were only 12v I believe. Mine is a 29l grey model with dark lid but off hand dont know exact model/date (bought it 2nd hand). Want to run it in my truck which is 24v and would rather not have to fit a reducer to bring it back to 12v if not necesary. thanks..

I'm pretty sure they are 12v DC and 240V AC. Haven't heard of any Engel having a 24V input, then again - I may be wrong.

Does the truck have 24 volt batteries or is the 24 volt achieved by 2 x 12v or 4 x 6V batteries being wired in series. If the latter, you could steal a feed from one of the 12 volt batteries or two of the 6V.

If the truck is not a toy 4WD Nissan or Tojo but a real one, read large and imposing, then I would assume its a work vehicle and constantly on the move. If so stealing the 12V from one of the batteries should not pose a problem.

Hi John

yep its a mitsi 8 tonne. Has 2 x 12v. I have used that method (running off the 1st battery direct) previously and in fact thats how my CD player is running, however I know from past experience the battery that has the 12 volt draw on it always seems to last a lot less time than the one on the 24v side. The new Engels will run direct on 24v, thats what the website says anyway

I think the older ones were either 12 or 24 not both.

Old dog - Old tricks but now with new knowledge re 24V.

As for "Toy Trucks" - safe at the moment and firmly in Tojo territory as hiding in Tom Price for a month.

Bit wet up here at the moment tho it was interesting to see the guy in Karratha do a flotation test on his PLaydo in the Turner River last night.

Best pic ever saw was two blokes sitting on the roof rack rack of their swept away Tojo P/C 47 series in the middle of a river with fishing rods and XXXX in hand. Classy act!

John L G,

PLEASE PLEASE don't run a fridge of the centre tap of a 24v system to get 12v without making other alterations. i.e. It is not correct to say "so stealing the 12V from one of the batteries should not pose a problem".

It WILL create problems, unless the battery voltages are equalised. Redarc sell a device to do this. If the level of charge in each battery is not balanced by an external device, the batteries do not do this all alone - unlike when they are in parallel. One battery will be overcharged and die of being boiled dry, the other battery will die because it is undercharged.

The other alternative is run 12v items via a 24v/12v reducer, but draw is limited by the devices capacity, unlike the balancing device that allows high current draw which is then balance back over time.

There are many comments on this in other threads for more details.

Thanks Derek,

That's not an exhaustive model list.

Mine is an olive green lid 27l model from around 1979. Model MRFT-530-A4 .

The internal inverter specs say 12v input, output 20v AC. The label on the input plug says 12V/240V, so though I'd prefer to run on 24v and have the ability to do so, I'll be leaving mine on the 12v.

It's not that hard to search the Engel website and find info out direct from the source. www.engelaustralia.com.au then go to products then to past products. I found mine listed there, confirming the specs above.

I was under the impression that most of the models were 12, 24 and 240 Volt. I am pretty sure my 40L will handle one of either of the 3 voltages

Zapper,

all current Engels from the 17 upwards all support 24v.

As you dont know age of yours prob best to contact Engel with serial number and check before you fire it up. no pun intended!!

this link may help but they are not the worlds quickest email reply service!
