Who is the OEM for this PSU? Multicomp MP711057

Does anyone know who the actual OEM is for this power supply?



Farnell are selling it under their Multicomp branding, model MP711057.

I'm sure I've seen an almost identical looking one under another brand name, but I can't remember where or what. Hoping I might be able to get the same thing for cheaper direct from AliExpress or similar. Unless it's crap, of course... ;D

HwAoRrDk:
Ah, thanks. :-+

Haha, I feel stupid now. I'd already looked at Owon, as I recalled a review of one of their PSUs on YouTube some time ago, but it was for the SPM series, so I discounted them as it wasn't the same. Should've actually persisted on that trail and actually looked at their website. :)

Seems one can get the Owon SPE3103 - appears to be the equivalent model to the MP711057 - on AliExpress for about £20 less.

Avoid - I got this Owon branded one (60V version of same PSU) for 90 quid on amazon (black friday) and it was so bad I returned it: https://www.amazon.co.uk/gp/product/B0C2CNYN2P

Way too noisy, both electrically and acoustically - had a look inside and it seems the main culprit is the rectifier diode and snubbers, which get stinking hot regardless of output power so need constant cooling, and there's also 100s of millivolts of switching noise spikes (see scope captures attached).

I really wanted this to be usable given the price and form factor but sadly it's not.

Not really.
from Farnell, £130.51 ( ex VAT ) does not include VAT.
from Aliexpress Total €107.99 Inclusive of VAT
I don't know where I can change the currency at Farnell, but if I calculated correctly, it would end up costing me over 200 Euros from Farnell.
