|
|
I'm looking for a source of approved relays for a project I'm working on that will need a field approval. The airplane is a Cessna 207 with a 12 volt system and it's getting a 200 amp alternator and a 60 Hz 2.5 kW 60 Hz inverter.
What I need are a DPDT 14 volt relay and a DPDT 120 VAC relay that I can use to get the switching logic I need to switch between ground and flight operations.
Actually I have space-qualified relays from Potter & Brumfield and Filtors Inc. but they are no longer made and never had any kind of FAA certification - only NASA and perhaps the USAF. They'll work fine but I can't document them for the feds.
The transmit/receive relay from an old Narco COM11 is one option but they come from the likes of Digi-Key and don't carry a PMA sticker unless you're Narco or King.
Any ideas?
