Are these load banks 400 hertz? They are for aircraft, and aircraft are 400 hertz.

It says. 1. General. The dunny load is designed to perform electrical loading tests on power plants rated either 28 volts or 120/208, 3 phase, 4 wire, 400 cycle A.C.. Both Dummy load systems (A.C. and D.C.) may be operated individually or simultaneously without influencing each other's loading capabilities

400 cycle = 400hz

In the manual, does it specify you can also use 60 hertz, (cycles)?

Those are big bucks. Better off selling to someone who will use it for load banking ground power gens and buy yourself a nice civilian load bank with the proceeds. I won one of those a few months ago. Had the paid inv and then the gov took the thing back.

The gov took it back after you paid for it? Have you picked it up? Will it work with a Mep 005a? What did you pay for yours? I paid right at 400 with the taxes and fees. Thanks Bernard

What are the civilian load banks going for?

Same one as you have. Never got to pick it up the gov backed out of the sale. They can do that. Not the first time it happened to me. I use big 3 phase heaters to load bank bigger gens. Couple thousand for a real load bank. If the 400hz one you have is in good working shape you should have no prob getting that for it.

Will this one work for my MEP? I'm not looking to do lot of load testing just trying to check a few things on my MEP. I love the design and the portability of it but will part ways with it if it wont work with my setup. Thanks Bernard

Maybe. Your gen is 60hz not 400hz. The load bank you have is intended for aircraft ground power testing.

In message #3 you showed us a picture of the manual. That's the reason I asked in message #5,"In the manual, does it specify you can also use 60 hertz, (cycles)?
So you tell us, what does it specify?

Resistive load banks shouldn't care what frequency is applied.

What about the fan motors, relays, lights and all the other goodies in the load bank?

The only information I can find is on the directions and diagram on the inside of the lid. I have looked for a manual but havnt been able to find one yet

Is ther not a data plate on the side of the Load Bank that has reference to the proper TO needed for the equipment?

Yes. It looks like it's going up for sale!

Unless you test a bunch of DC power generation, I don't think you can use this load bank. It is primarily for 400 hertz gen set testing. And for gen sets you have never seen, let alone heard of. I spent 20 years in ADA, who only use 400 hertz gear, and could not use this load bank. We had 416 volts/ three phase 400 hertz gen sets. If you are going to buy it to resale, do it. But you can't use it.
This page reads all the fans and controls are 28 VDC. Loads are variable resistive. Will measuring have the same effects as delivering? I get that sending 400 HZ into a house wouldn't work but it seems a [FONT=higoim+times-roman,Times New Roman, Times, serif]resistive-reactive[/FONT] load should be okay for testing a 60HZ gen. Not saying it would work but thinking out loud. Might need to rig up a pretty potent transformer to power the controls and fans.
