Looking for a voltage regulator recommendation:

 

 I need a small 14 volt bus bar in order to service ray allen servos and maybe a couple other 14 volt devices.  I will be running a 28 volt system and would prefer to have a separate 14 volt bus.  If anyone has any recommendations, or tips on how to go about servicing disparate voltage components, I’m much obliged  --

 

 Thank you,

 

 Andy

Ray Allen makes a 12V regulator just for 28V aircraft, P/N REG-1.



Otherwise we've installed something like this for 12V items:

These days you can't really get by without a few 12V outlets.



When we had the luxury, we've gone so far as to install a complete 12V battery and alternator, but that was on a turbine with lots of spare drive pads.

Andy, 

  

I used a Collins PWC-150.  It has two independent channels, either of which will handle all of the Ray Allen servos.  I put an "on-off-on" toggle switch so  that I had both a primary and a back up 14vdc output.   Protect the circuit with a circuit breaker, and you are all set.   You can also use a King KA-39, although if I remember correctly, it is only one channel.  Either unit is available on E-bay for around  $100 or less.  Most avionics shops are littered with these units. 

  

On a side note, I just powered up my panel, everything works, no smoke, no components changed color, and no thermal events! 

  

Good Luck,

ok, that sounds like the ticket — thank you.  I found this part number after matching up the converter specs you gave me with DigiKey that should save you a few bucks if you need this again in the future:

 

 http://search.digikey.com/scripts/DkSearch/dksus.dll?WT.z_header=search_go&lang=en&site=us&keywords=102-2273-ND&x=20&y=15

 

 digikey part number:  102-2273-ND  this is a smaller device and 12.5 amperage output.

 

 Just wondering if you guys use an inline fuse with this type of device?  Or would you rather have a breaker available to the pilot just in case the device ever has an issue in flight?

 

 Thanks for the recommendation  --  

 

 Andy
