I have a data logging system at a remote site which runs from a 12 vdc deep cycle battery. A solar panel keep the battery nicely charged.

I need to add a 24 vdc supply to power a few 4-20 milliamp loop powered sensors.

Any suggestions for a quality supply that would take 12 vdc and turn it to 24 vdc?

I'm guessing I would need a few hundred milliamps for my three sensors.

I'm not looking to build anything, but an off the shelf device that won't break the bank.

Thanks,
Steve
