24 volt supply needed ?

[makeitfit]

Help needed please.
All you sparky types I have hit a snag on the supercharger install
I just found out the electro clutch thingy is 24v :doh Is there any way I can utilise my twin battery setup to join them up for this task only?
Cheers

Surly theres a way of converting it to 12, have you even tried it on 12? It might still activate.

Not yet, didn't even think of it :doh I'll zap 12 up it tomorrow :thumb2

12-24v dc-dc converter would be easiest but £ depends on the amps it needs. I can't see it being easy to link up the batteries and keep the split charge for your winch battery but I'm no auto electrician:nenau

I like that idea :thumb2 I'll see if it's rated, ta

can you put a test meter on the clutch coil and let us know the resistance, might be able to figure out some options then.....

Yep I'll do it tomorrow :clap

Couldn't see it eating many amps tbh.

As a guide,.. 12V air con electro clutches can measure around 4 ohms or so, that's around 50 watts.
Your SC clutch has to handle some 10~30 HP?, so I'd expect the clutch electro mag. to be fairly substantial.

Coil resistances in single figures are probably the order of the day, tomorrow will tell.......

It was talked about a few months back, as someone had occidentally got a 24volt winch, and the practicalities were a nightmare. I think in the end it was decided it would be easier to get a second 24v alternator and bolt it onto the engine.

Depending on the current drawn, and like rayf3262, I would expect it to be somewhere around the 4 to 8 amp mark, as a pure guess, then your easiest way would probably be to use something like this... (They are not cheap though)

and this one is a bit cheaper

dc to dc converter found on on the net £25 quid 84wats max out put should do the trick i think maplins also do them bt havnt had a chance to check

Yes there is... More later if required....
BUT you will also need a method to charge the 2nd battery whilst running. Best not to go there unless this is the only option, but you could test it at 24 volts for short periods, to see if it works before going to huge expense.

BUT better to have a DC -DC converter if you can get the power.:thumbs
There is one on ebay 240 watts BUT... The motor is an inductive load and could destroy a simple converter, so choose more power than you need.

pete if you know anyone with a decent meter you could temp run it on 2x 12v linked to see what sort of current it will pull.

 

[solarman216]

as with most electro magnetic devices the initial pull in is high current but to hold it there is a lot less, so my answer would be a small gel battery arranged via relay's to do the initial pull then switch to 12v to hold it there, a thought any way, Rick

Have you tried it then:nenau

Not done anything today, I've been working
Tomorrow I hope :thumbs
