so regular incandescent lights will be fine on 400HZ as they are a purely resistive load, i doubt you can lower the rpm enough to get a 60 hz output without causing issues, if you want to run anything "normal" besides lights like another person said best bet would be a dc to ac inverter on the dc output depending on its voltage. cool find though! i didn't know these wer a thing and i have a new mep gensets myself
wow that is insanely cool!! Is it true that they are only fuel efficient when operated at near full-to-full load? also would be great at remote places, you can use the exhaust heat in a co-gen recovery system for hot water/air - even more efficient then
It's driven off a reduction gear box. There is one compressor and one turbine in the engine, which spins at 52,000 RPM then is reduced to 8,000 to drive the generator. I would love to hear it down further to run a 60hz generator but that will probably happen well into the future.
@@Pyro15D from my looking around it will be hard, as 400hz will make the windings in the alternator alot smaller than on similar 60HZ equipment so most likely not enough power to drive a similar 60hz gen head, but gearing down to 3600 should be doable with some pullys or gears, ez is just a rectifier and a inverter since its only a few 1000w
Non 400 cycle electronics don't like the 400 cycle, learned that in the military after plugging a radio into the convenience socket on the Sentential Radar generator...
Tachometer inop is the fault. Without tach signal, the fuel control can't sense if engine is self sustaining. This is a single shaft simple centrifugal compressor so it is quite fussy on startup.
That's what I thought too, but according to the wire diagram on the unit, the tachometer signal doesn't interface with anything other than the gauge. There is a separate tachometer signal produced from the generator head and that goes to the control circuitry but that works since the starter shuts off automatically.
That's what I think too. I disconnected the cannon plug on the generator head because I didn't want it to generate electricity while I was digging through the wiring and when I went to start it, the starter didn't automatically shut off. I had to quickly flip the master switch to shut it down because the starter motor was still running and it was almost at full speed.
It's got a lot of potential. What a great little toy!
what a beauty

with this being higher output dc, it may be more effective to us a dc to ac inverter to achieve your desired 120-volt ac usage for this equipment
100a at 28v, only 2800 watts, maybe a 2000w inverter max accounting for losses. That's a noisy 2000w.

Very cool! I have often thought about playing around with a gas turbine engine, but what would i do with it? Question answered. Thanks for sharing!
Wow. Great project. Is the genny driven off a reduction gear or a separate power turbine?

Would you sell it?
A 24V inverter should work great with that, get a 3kW one.
It might be low on oil, etc.
there is nothing comparable to a turbine spooling up..

Doesn’t he tach reference for these units read another speed input for startup. The tach on the main panel is separate and just for indication
