Power plug and charger

[Coast Iron]

I have a 2009 DA40 and want to plug it in to play with the G1000. I want to purchase the plug and charger. Please give me some advise!! Thanks in advance.

You will need to get a GPU like this one.

As a sometime electrical engineer, I couldn't see paying the exorbitant prices for an aircraft GPU. So I bought the Cessna plug on Spruce for $40 and an Omron 24V 10A power supply off EBay for $30. Wired them together and voila! Aircraft GPU for $70! I would trust Omron (a leading high-quality Japanese power supply and electronic components company) vs White Lightning. 10A is plenty to run my G1000 in the hangar. It may not be as pretty, but one-tenth the price!

If that URL is dead, search for Omron 24V 10A power supply

Sounds like a nice low cost solution for the DA40/180.

I don't think that will work on a DA42/62 which has a higher current draw. When the supply is first energized on a 42/62, and the G1000 is powering up, the hydraulic pump for the landing gear begins running until the pressure is restored in the landing gear system. If installed, the radar will also exercise its servos.

Another use of the GPU on a 40NG is to power the ECUs while downloading engine logs. I don't know, but the G1000 plus the load of the ECUs may exceed 10a.

And on every plane, accidentally turning on the pitot tube heater generates a high current draw (and may melt the cover).

I suppose someone can put a clamp meter on the DA40/180 and figure out how much current the G1000 alone is drawing.

I heard from a friend that you can use a 20 amp power supply to run avionics on a DA42 if you first pull the circuit breaker for the gear. No radar installed. Not a bad idea to pull breakers for the fuel pumps as well. Don’t forget to forget to push them back in when done.
