Power supply for home lab - do I really need a R&S?

(1/22) > >>

FranciscogGomez:
Hello everyone,
A couple of weeks ago I sold my cheapy single-output power supply for good beacuse it is time for me to buy a more decent power supply for my home lab. it will be used mainly for my personal project but also on project from work (HO). These are the requirements:
Hard requirements

* two or three independent outputs
* Protections: OCP & OVP
* Voltage accuracy: <=10mV
* USB or ETH port for basic controlling
Mild requirements

* Sequencing/programmable feature (it's a nice plus)
* Lightweight. (Linear power supply is not a hard req.)
* Price: ~500EUR & ~800EUR 
I have narrowed down my list to the following table:


The best option that I have is the GPP-4323(dark green) but my "professional-side" inner voice it is telling me that the NGE-100 series is a good option for me as well. (realistically, a used one)

I want to debunk the need of a power supply from Rohde & Schwarz and for this, I need your help.
so my question is:

* has anyone bought a power supply from the NGE-100 series  and regretted it?
* if so, could you tell my why?
Cheers
Francisco

Dear Sr. Gomez:

Very fine and detailed post.

We can assit you better if you can precice your applications and experience:

eg: you are Beginner, amateur radio, techincial, emgineer, ?

uses: Testing and developing microcontrollers?
General analog circuits?
Batterty charging?

As a hobbyest since 1950s and Electrical enginer since 1968, we always used HP, Lambda, Tek dual or triple linear supplies with analog meters.

We have paid $US 10..50..75..and $250 max.

We found thewm on epay, Ham radio fleas, local asds like craig list etc.

We have no idea for the Chinese or Rhode and Schwartz you seem to be prefering.

We are wary of fancy digital controlled PSU as they are no as reliable or robust compared to simple linear.

Bon chance


Jon

Hello,

Here is PSU from UNI-T: https://eleshop.eu/uni-t-udp3305s-power-supply-5976.html
I ordered that one two days ago, it should get delivered this week :)
People sad good things about that PSU, and it checks most your requirements, and price is great.

Ice-Tea:
Minor remark: if you're actually looking for a 10mV accuracy on your DUT, you kinda need remote sensing. Otherwise, that 10mV is just a number on a screen ;-)

nctnico:
I'm missing the Keysight E36313A from the list. A rather unique feature is that it has two current ranges so it can measure low currents more accurately compared to other PSUs.
