Searching for AC+DC Power Analyzer recommendation (IT9121, GPM8310...)

(1/2) > >>

MaTkEOxjC:
I'm currently looking around for a AC(+DC) Power Analyzer and I did not find that much stuff in the forum so far. Kinda suprising.

I'd like to play a bit arounnd with AC power supplies.
Look at Power Factor, Crest factor, harmonics standby consumption, PFC, Inrush current.
Would be nice to be able to do some compliance testing in the future (EN 61000 Harmonics, EN 50564 standby consumption).
Maybe some DC analysis.
A graphical UI with waveform display would be nice. USB & LAN interface should also be present.

I've found a few devices which are interesting and fit my 2k€ budget;

* Itech IT9121 which is ~2000€ (IT9121E is €, but does not have the harmonics option)
* GPM-8310 is 1438€ or 1545€ (later with Digital-IO option)
The UI seems to be not fully intuitive and it cannot really measure inrush current apparently.
All prices with tax in Europe.

I also came across the Rohde & Schwarz HMC8015, but that's kinda above my budget.
Also they have some stuff locked behind software options which I dislike.

Just missed a Chroma 66205 on Ebay for 500€. This does not have a graphical UI but comes with a PC software.
New this ia also above my budget.

Has anyone one of the two devices and can tell me what they like/dislike about them?
Or some general thoughts? :)

Have you considered a DSO with a Power Analysis option ?
Do you already have current and differential probes ?

SDS804X HD with PA option ~$700

Yes, I considered that. I've got a MSO5000 with power analysis option, but missing the probes.
(Micsig CP2100B 380€+ DP10007 200€, in total that's just shy of 600€)
This might be an attractive option regarding the inrush measurement.

While this gives some parameters, it's also seems rather limited. Not sure how well it can integrated regarding short bursts during standby.

tautech:
IMO you need explore your DSO's capabilities further and NEVER disregard what additional probing solutions can provide for other projects.
A DSO without current and differential probes is severely under equipped to extract its full capability.

Using that logic, I should start buying a lot more stuff for the home lab no matter if it will ever get used or not.   

Depending on your skill set, maybe even roll your own software/hardware.   Shown using some funk transformer and LEM sensor to measure the power.
