Is there a better power supply option for $700?
(1/11) > >>

I am doing some research into purchasing a power supply.  I've narrowed it down to Instek GPP-4323 (LAN)

I need a power supply for basic general needs and for learning basic electronics stuff.  Some of the uses would be for.

Working with microcontrollers Arduino etc.
Working on current sensing and voltage sensing circuits.
Working with and designing operational amplifier circuits.
Charging all sorts of batteries.
Working with smaller servomotors.
General electronic needs.
Repair work with voltage injection etc.


My reasons for selecting this particular power supply.

I like GW Instek.
Seems to have decent specifications.
Low ripple.
Decent response time.
Is able to function as a load (as far as I understand although it is limited in capacity)
Seems to have a pretty decent user interface and layout with extra buttons for convenience.

I am looking for the community's help in making this decision.   Also would love to hear from anybody that has actually used this particular power supply and there experiences.

I am looking primarily for something new not used off of eBay.

This power supply is probably way overkill for the needs that I have but I believe in buy once cry once approach to purchases.

If there is something in this particular price range that is better I would love to hear about that as well.

I would like to thank everyone in advance that contributes to this post.

Thank you.

Getting a good quality PS for development work is a good decision, many folks don't and suffer the consequences!!

The GPP-4323 is an excellent choice, we have one and use it. Having 4 controllable outputs is a plus in many uses, and the EL is also a nice somewhat unique feature is this price range. This supply is accurate, stable, WO overshoot on Startup and Stop/Unplug, so good to use with sensitive low voltage circuits.

We also have the SPD3303X (have 3), however these don't have 4 outputs, and only 2 are fully controllable. This is a good supply for the $, but lacks the features of the higher $ GPP-4323. Siglent has introduced a new PS series, but no reviews yet, and availability uncertain.

Best,

If I had that money to spend on a PSU, I'd have no problem purchasing another EEZ BB3:

Thank you for such a detailed response.  I had a few follow-up questions.  The load feature,  what is the maximum that it can be used for?  Would it handle something like 12 V at 3 A? 

What is something that you dislike about this power supply?

Thank you for the recommendation.  I tried researching the price on Google.  It seems like a very convoluted buying experience.  Also it's made in Croatia so how is warranty work going to work?

I'm sure it's a wonderful unit with better specs but just not for me.
