Re: 24 volt power supply in a 12 volt aircraft.



A cheap and simple solution might be to just buy a power supply that gives 24v from
a 12v input. For example Altronics sell a 'Car Laptop Power Supply' which provides
a choice of output voltages from 15v to 24v fully regulated at up to 3.5 amps (from
a 12v input) for only $49.95

Catalog number M8626

www.altronics.com.au

I should think other stores like DSE and Jaycar will have similar units on offer

Hi folks,

I have access to a very good aircraft radio, at a very reasonable price.
The problem is that the aircraft that needs the radio is a 12 volt system,
and the radio is 24volt.
Are there any reasonably inexpensive options? I guess we could add
another 12 volt battery, charge them in parallel, and take power off in
series. Are there step up voltage modules out there that would support a 5
watt transmitter?
