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 swit ch so that I had both a primary and a back up 14vdc output. Protect the c ircuit with a circuit breaker, and you are all set. You can also use a Ki ng 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 a re 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, David Vorsas Radial Rocket N385BV From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectr ic-list-server@matronics.com] On Behalf Of Andy Hawes Sent: Wednesday, January 04, 2012 5:18 PM Subject: AeroElectric-List: 14 volt bus / voltage regulator? Looking for a voltage regulator recommendation: I need a small 14 volt bus bar in order to service ray allen servos and may be 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 recommendat ions, or tips on how to go about servicing disparate voltage components, I' m much obliged -- Thank you, Andy This message has been processed via your triumphgroup.com e-mail address. ________________________________ Message 2 _____________________________________ Time: 02:08:23 PM PST US Subject: Re: AeroElectric-List: 14 volt bus / voltage regulator? From: Andy Hawes ok, that sounds like the ticket =8B thank you. I found this part number afte r 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& l ang=en&site=us&keywords=102-2273-ND&x &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?
