Electronic Load

[George S.]

Just purchased one of these. Offered $45 and offer was accepted. They've sold 11 and have 1 more to move.

Interesting ... what do you do with that? Amplifier load testing or some other use?

 

[George S.]

Power supply testing. Have heard there are other uses like battery testing. More research is needed.

So, buy first and ask questions later?

 

[George S.]

No, I have power supplies to load test.

 

[George S.]

Last one is sold. Someone here get it?

 

[wattsabundant]

If it's an electronic load, It's not likely to be purely resistive. Probably a high frequency switching device. If that's the case it wouldn't be good for testing amplifiers.

 

[George S.]

Don, I was going to go back and find your post about using water heater elements and cut and paste it here. How did that work out for you? I think about it every time I walk past the plumbing section.
I'll probably eventually try something similar. I just don't yet have the knowledge or time to do so.

 

[wattsabundant]

The heating element works really good. If doing a 700 the elements would need to fully emerged in water. Otherwise they’ll quickly burn up. I V melted the plastic lid on the 5 gallon bucket.

Y’all know Don is actually a real mad scientist right?
Lol …in action

 

[George S.]

Spencer, I appreciate the photo! Do you use one element per channel for a 400 and two per channel for a 700?

 

[NeverSatisfied]

We were testing a couple 400’s that day but honestly I don’t remember the answer to your question. Hopefully Don will be along shortly with the information.

I hope that speaker wire is oxygen free...

 

[wattsabundant]

The heaters are slightly less than 8 ohms. The cables have dual banana jacks on the other end. For 4 ohm testing, 2 cables are plugged in to each channel. Zoom in on the photo and you’ll see the area that melted.

Cryogenically treated.

 

[George S.]

Thanks Don and Spencer. I'll eventually get one built. Yup, I see that melted plastic!

Hmmmm maybe I should get a dual 500, hook it to my water heater, and put Shpongle on repeat…….

Now that is in the spirit ofPhoenix.

Steam Shower upgrade…..lol.

And the cooling fan can heat the room. Bonus.
