So after speaking with the guy from 400hz repair a little more and trying to sell him the load bank we established that mine is older since it has the 400hz fans. They changed to high voltage dc when covid made it impossible to get replacement fans. I am learning more.

Right. I actually did that already. I took a 10kw heat kit for a furnace and ran a fan across it and it worked really well but the load bank looks nice and clean.

Heck the fans will still be spinning 1200 rpm. Lol.

That's funny because the guy from 400hzrepair told me they are high voltage dc but they are 3 phase.

So here are a bunch of pics inside the bank. The only thing I see that might care about the hz is the transformer and what I believe are little rectifiers. Even the CT is 50 to 400hz. Any one see what I'm missing? 2PBFeet seems to be very electrically save. Do you see anything? Would the...

Definitely better than nothing!! Heck he did even answer a couple questions. I'm still dying to know what about it is only 400hz.

Yeah I guess a 10kw switch would be pretty big hu? Maybe I'll use breakers or something for the stages. Maybe I'll just try to sell it and wait until I can get the right one. I have kind of a bad habit of jumping before I look. The info was kind of hidden in the listing and I would have had to...

I reached out to 400hz repair and they at least answered me. I'm not getting any more than this though Well Sir, You purchased something that was specifically made for the Patriot Missile System. 400 HZ is the only Frequency that it works at and the input power that drives the LB is 115 phase...

Toggle switches. Not bolts

That is kind of my plan if I can't use it with its circuit board then use the coils with toggle bolts and an external fan. It is a nice load bank though so I would like to find a way not to butcher it. Lol

I guess the first time I try it I can use my 15kw gen and put it on 415 just to see how it likes the 60hz with everything else the same.

Thank you for this. I does look pretty similar and should be a start.

Copy that. Thank you for looking into it for me. Once I get some time I'll open it up and see if the fans are DC. They look like computer fans. After that I imagine I'll put some voltage on it and see what happens. I think it's kind of funny how much awesome documentation they have on things but...

I'm hoping I can either use it at a limited capacity or possibly modify it a little to use 60hz. Maybe I just sell it if not. I'm wondering if the heat coils will care about the 60hz. I can bypass all the electronics with toggle switches and run an external fan even if the heat coils will be...

Hello. I bought a load bank from the auction and it didn't have any part numbers and they conveniently didn't take any pics of the big 400hz stickers on it. I've since gotten my hands on the nsn. Here it isNSN 6150-01-486-6937 I still can't find any info about the thing except that it's a load...

I guess I don't know the answer to this question but I was watching the auction for these generators and couldn't figure out why the head looked so discolored on one with very low hours. The paint hadn't even been burnt off the exhaust manifold yet but the heads looked burnt. That machine also...

It did go okay. Thanks for asking. We got home yesterday. Long trip but I chose to risk towing the generator instead of taking my 40 foot trailer up empty. Luckily it towed beautifully with no issues

It's amazing how much knowledge is on this site..

The first time I saw that setup I was stumped for a while looking at it thinking if the contactor drew in it would be a direct short phase to phase. Then I got my hands on the schematic and realized what was going on.

Yes mostly. Like Rickf said above it probably doesn't have much load to start but not knowing the machine it's possible for it to draw quite a bit during start up. I agree that it probably will run it especially since these 803A's are really more of a 12k gen.
