TTi MX100TP triple power supply teardown and review

<< < (6/11) > >>

Robaroni:
I've had this supply for a couple of years now and it works extremely well. Every once and awhile I get a turn on failure but I just do a quick restart and it's fine. I opted for the MX100TP because I do a lot of low current work and I wanted the extra precision on channel 1. I have several other supplies so I don't need the high current. I have an old HP 6632B (one of the best supplies ever made) on the rack too but the TTI is quieter and when a supply is running for days in a set up that makes a big difference to me.

I really think this MX100TP PS is a Best In Class for low power setups ;D

MX100TP Power Supply covers all my needs. So you've remoted this PS thanks to a computer, but how did you proceed ? I mean by software. Did you use an excel sheet ? Maybe could you show a printscreen ?

I've written a bunch of GPIB utilities in perl and bash that read/write data to instruments, and there's another bash script which does the stepping and outputs to a CSV file.  I usually read the CSV file into octave for more computation and/or plotting.  The utilities run on linux and are all command-line driven, and they use the linux-gpib driver for all the underlying communication.

I'm sure it's underwhelming given the fancy GUI packages available today, but I've been using it for at least 15 years and unmotivated to change since it works.

The unit came with a CD that has:

  IVI Driver
  LXI Discovery Tool
  National Instruments Driver
  TCP Example Program
  TTi Firmware Update Utility
  USB Driver

  (and user manuals in various languages)

These are all windows bits, so I can't vouch for how well they work.  But at least supported GUI option(s) are available.

These jumpers look ok to me.  I measured the binding posts on the unit to be 20mm deep and exactly 4mm in diameter.  The metal contact sleeve inside the binding post is recessed about 3.1mm.

It appears that these jumpers are the ones with a contact cage that rotates?  If so, I'll add that I haven't had good experiences with them on any equipment since the contact between the cage and shaft can wear and become intermittent.  Maybe the ones I had weren't quality enough to last.  But after several frustrating events at high currents, I now only use fixed contact banana plugs, specifically the Pomona Model B stacking patch cords.

skYfIrE:
Hi MarkL,

So, you manage a voltage ramp via a csv file which is similar to Excel. I'll check how it will be obvious to proceed.

About my terminals, I'll use terminals from PJP. They have a website with a complete portfolio : http://www.electro-pjp.com/sites/default/files/catalogue_1.pdf but I don't know if they have a distributor in US. You have some options with many quality levels, it's up to you, you can ask a custom-made cable (even with NiAu coating) ;)

Evodad:
I know this is an old thread but I try to get an answer anyway  ;)

Some in this thread have said the MX100 is fairly quiet. My impressions from this Video tells me it is quite noisy ?
Just listen in the beginning before turning on and at the and when turning off.


Is the video misleading. Yes I am thinking about buying the MX100, but not if too much fan noise.
