Power to the people! We guarantee that you'll feel more powerful when you conduct your aircraft testing and servicing with the Bycan PS-28100 auxiliary power unit. Or at the very least, you'll be able to get your work done efficiently without running out of juice. This heavy duty APU plugs into your aircraft's APU connector and outputs 28 volts DC at 100 amperes. It's just what you need to test your landing gear and the filtered DC power is perfect for checking avionics equipment. When it's plugged in it automatically disconnects the battery to avoid drainage. This particular model uses 230 VAC, 50 Hz line voltage and has a Cessna style AN2551 plug. SkyGeek.com has been in business since 2003 as your 1-stop shopping source for aircraft equipment, parts, tools and accessories. This unit only works with 230 VAC vs 110 USA - it won't work in the USA as it is a European version.
