Which DC Electronic Load To Get?

[steve1515]

Did anyone ever figure out how to get one in the US? I'm looking to get one as well.

On Amazon there was a seller called JUMO Trading LLC that had reasonable prices on the Maynuo 9712 with the M-133 USB interface cable but they weren't anywhere near $318.  Might be worth an email to JUMO (via Amazon) to see what they tell you.  In my experience JUMO was very, very responsive, YMMV.

Also saw this:

- don't know anything about this seller or if their price includes the M-133

+1 for Maynou (M9712C, 150V, 60A, 300W)
I where in contact with Maynou directly to get help on how to calibrate, they seemed open to direct purchase (but maybe they thought I was a company).
But if lots of people here are interested maybe Maynou would be interested too?

Thanks! I'll have to send a message to them.

They don't come calibrated when you buy them?
What is the process required to calibrate one of these?

[cosmos]

No worries,
It came calibrated, even had papers about it.

My M8811 also came calibrated, but the 5.5 digit DVM channel was slightly off (about 20 counts if memory serves) but still inside the specification.
I wanted to have it better than that, and it was very obvious it was off since the output voltage reading (later shown to be dead on) did not match the DVM.

It looks like I can find the M9812 on eBay for less than the M9712. Is there much difference in the two? They look identical.

[steve1515]

I've checked the specs on both the M9712 and the M9812 and they both look identical except that the M9812 has an LED driver test mode. I'm not really sure what that is since I can't find any documentation on it.

[steve1515]

So, I ended getting an M9712 from Amazon. I received it a couple of days ago, and it works nicely. 

One thing though. I'm not really sure I understand the CC+CV and CR+CV modes. Can anyone explain these to me?

If you do not yet have an exaxt need, likely the voltage and wattage features would be more useful than all other features.  I have 2 arrays, not as pretty, but have been doing the job very well.  Especialluly as loader for unknown power supply quality, I am prepared for them to be blown off.  But been 5 year for 1 and still stay strong.  My usage is almost daily for 1.

Yes, I second the Array 3710a  , I've been running it ragged and it never gets hot even at full load, 200W.  Its built like a tank and likely very durable as a unit, the software is very mediocre, at best.
