Cockpit electrical power

Any good?

For the moment, I use a “big” transformer 220v to 24v, it provide the power for a static inverter ( to get 26v and 115v 400hz, used for resolver), the 24v is used also for general illumination.
For some electronic device (like landing gear sequence), I use a power supply from a old personnal computer (5v and 12v).
Nice week-end

So how do you power up your cockpit? Anyone have a solution that can plug into a wall socket?

This is how we put power on WH779 beats having to use our 28v aircraft battery’s that don’t last long…

Advance Switch Mode Power Supply 28v DC 100A

Model F20006

Input Voltage 184-264v AC(20A Max)45-65 Hz

Output Voltage 27.2v DC(Can be Increased or decreased via O/P Adjust pot)Set at 28v DC

Output Current 100Amps 2.725 Kw

As the others have said, 2 12V car batteries will do the trick or a 24V truck battery. They will not last long though without external power, in my cockpit I have a large 28V power supply (turned down to 26V) which I bought off the net and which I plug into mains power. When you get around to powering it up try and pull as many fuses for items that you won’t see but use power such as radios and pitot heaters.

This is ‘similar’ to my power supply although I paid a lot less for mine, just posting it up to give you as many ideas as possible.

Since even a type 100A or 100B inverter will draw about 12 amps at start up, I use two 12V batteries and a 24V “Startmaster” battery charger. (as already posted!)

XF382 at Coventry runs via a custom built transformer box which is mobile on a trolley. Second one built now as the first I obtained suffered a failure when used on another aircraft. That first unit was made specifically for the Hunter’s power requirements from a local chap who used to build transformers for industry and he was ex-RAF so knew what I required. Sadly I don’t have in-depth details of either to hand at the moment but it involved calculating current draw of all that is live on the Hunter (including inverters). I had to isolate the radio stuff though as they drew so much current and weren’t really needed within the Museum environment…

Inverters draw quite a lot on start up (10—15 Amps even for the small 100A or 100B types) so I use two 12 volt car batteries which can provide sufficient for the inverter and a “Startmaster” 24V battery charger to keep them topped up.

I have no idea :p basically looking for general ideas as to how other people power cockpits. Interior lighting mostly, maybe one or two inverters for artificial horizons. no-where near powering up myself, but maybe in the future.

How much of it do you want to power up? How many amps do the various circuits draw?
