Triple Output Bench-top power supply - Any requests?

Magnethicc

Hi Everyone,

I will be designing a high performance triple-output bench power supply and I was wondering if any of you have any information regarding your current benchtop power supply:

1. what do you like about it?

2. what do you don't like about it?

3. what kind of features is missing as of today and wish were available?

feel free to go nuts, any help is greatly appreciated!

    As is common with questions such as yours I find that replies (including mine) focus on the current project. One of my current projects is a switching supply for precision motor control  - its a buck regulator designed for very high efficiency and fast dynamic control of the output voltage.

    It works with anything from 10 - 60V input and may draw up to 10A from its supply, it is capable of 8.5 to 60V outputs at 6A (8A for short periods). The efficiency is between 90 and 96% for any combination of input and load above 0.5A. It has built in pull down for fast output voltage change with low or zero load.

    Now you can see the form of my PSU requirement - currently I'm using the AimTTi MX180 for the supply but it cant provide enough current at 60V. I'm using a Rigol DL3031A electronic load and a Keysight DAQ970A for data acquisition with a custom interconnecting box for current measurement.

    It's all controlled by a PC via Ethernet. 

    If I want to test at full input power I have to use a brute of a supply which has only manual or analogue control and can do 100V @ 28A.

    I want  a load which can simulate a motor type load and feed power back into the supply.

    A typical source meter can do all this but only at low power.

    Analogue modulation allows you to connect an existing programmable waveform generator.  A built in one would be fine but all to often these are poor second cousins to a decent signal generator. (You need triggering, slew rate control etc).

    A single box solution to this problem would great, but unlikely. I think Keysight can do it (just about) with multiple boxes but very expensive.

    So in the end I'll do the motor load testing with a motor !

    Could you explain you project a little - is it commerical, marketing, fun or something else.

    Please read    's information and arguments again carefully.

    I agree with him; I think similarly.

    BUT --- What is YOUR wish?

    You haven't answered any of the questions so far. Wink

    The real point is: what do you need for yourself? The thoughts and wishes of others are rather irrelevant.

    You have to choose what's right for YOU, what functions it should have, and then you have to calculate YOUR costs accordingly.

    It is handy to have a USB connector that can supply USB voltage and display how much current the load is consuming.
