TTi MX100TP triple power supply teardown and review

<< < (3/11) > >>

MarkL:  Nice teardown and review.
I have been using my MX100TP periodically for the last 10 months, and it's always worked well.  I ran a few simple checks on the load and noise , and as in your review, everything was as advertised.
I had been looking for a nice 3 output power supply and didn't really fancy the Rigol 832 series, so I picked this up instead (for a lot more money).  And, I feel that it was worth it.

thanks again.

Robaroni:
Mark,
Thanks, great review! As I said when you directed me here, I was thinking about the HMC4083 but it's a little anemic in the power dept. but it's really compact.

I think I'll go with the MX180TP.

Well I got the MX180TP (it was drop shipped from England). The literature specs it as having chans. 1 and 2 as 5 digit current and voltage but guess what? It's a mistake in the literature! I do a lot of low current uC work so I really wanted the current resolution. I got an apology from TTI, a thank you for telling them about it and a promise to correct it - just switched it for the 100TP. From what I saw on the 180TP this is a very well thought out supply. I really like the simplicity of the front panel controls and the meter is easy to read. You also have the option to reverse the display with a black background which I actually like more but we'll see when I really start to beat this supply up. Usually I find when you're working on a project and everything is going wrong that's when little snigly things bug you the most, like waiting for my Tek scope to update SPI and I2C bus data.
Anyway if you want a high resolution readout get the 100T (chan 1 only) or 100TP NOT the 180T. The other thing is the 180T has one supply that maxes out a 5.5V. I think the 100T is more versatile in that all the supplies are 35V at 3A. So if you're working with +/- 12 volts you don't have voltage above 5.5V if you need it on the 180T. The 180 does have more power out but it's above what I need most of the time, it's your choice both are very good.
The other thing that bugs me a lot is noise. I'll dump a test instrument if it's too noisy, my Agilent 34410a whined unbearably so I replaced it with the 34465 which is whisper quiet for those times when it runs all day doing histograms, I guess I wasn't the only one who complained to Keysight because they addressed the issue. Anyway you can barely hear the fan in the TTI, nothing worse that a noisy fan running all day in a supply.
Nice size but at 13+ inches could be a little shorter if it's sitting on your bench, mine sits on a shelf above the bench.
I'll try to update my views when I run this supply a month or so to add to Mark's great review. I definitely think this is better then the Rigol's, it does cost a lot more but didn't Dave recently blow up his 832? Maybe it doesn't cost that much more after all!

Apologies for bumping up this thread, but the MX100T model (with no USB, LAN, GPIB, RS232, etc) does NOT come with a USB. Thus,  it looks like the MX100T lacks the ability for FW updates !

Am I correct ?

I just looked at AMI's site and I'd say that unless you have a USB port on the back you can't update the instrument. Probably have to send it in for updates.

What is your firmware version? If it's 104 than it's the latest.
