Where can I find a voltage converter that will enable me to use 12V accessories in my cockpit? I have a 1980 model, and the 1980s and up are all 28V. What is the difference between a 12V system and a 14V system; or between a 24V system and a 28V system?
The aviation norm is to classify voltage by the charging value, while in cars it is classified by the battery value. A 14V charging system uses a 12V battery, and a 28V charging system uses a 24V battery.
Pilotdiscount.com is a good source for a fairly low-cost portable voltage converter for use with portable 12V devices. The price new is $59.95; lowest I’ve ever seen for a 28 to 14 (24 to 12) converter.
Here is the link. Note that there IS NO WWW PREFIX:
