Hi,
a colleage at my company obviously bought a hspy-300-03 via alibaba.
I don´t know the price but a short search showed offers around 450$.
Anyway he returns in a couiple of weeks and so did I pick it up.
When I read the printing on the cartonage I immediately knew I had a real quality device in my hands
On opening the Minus connector fell out of the box .... cleanly broken off .... great quality struff seemingly pressed from mud.
First impression ... well, ahem yes
Weird IEC-connector and even weirder adaptor without PE!
No CE sticker ... not even the fake chinese CE.
Second impression .... the casing is not folded to perpendicular shapes, but the front is slightly tilted in the horizontal ... and it doesn´t appear to me as if its related to the broken connector.
Anyway .... I opened it up to see the innards.
Large PCB on the second floor bends easily as there are several isolation slots across ... flimsy thing
Some inductances flying around .... mechanical construction leaves alot to desire.
Lets inspect the PE .... certainly not as it must be done ... just screwed to the IEC-connector fastening screw wo. washer and fixation et al. The lid of the casing also just relys on that 5 mashine screws will somehow make it through the laquer.
Small to almost non-existant isolation distances all over the place.
When my eyes fell on the big brown caps I first was positively surprised to see the well known NipponChermicon/UnitedChemicon logo ... well, until a closer inspection revealed that it were a case of blatant copyism .... Iron KingKong .... I almost fell from my chair LMAO
I admit I never heard of that ... KingKong caps I ´m still giggling.
KingKong even at the output ..... and of course bigger in value than healthy
The wiring also doesn´t look as if it could cope with teh specced 900W continuosly.
At that point I decided just to put that piece of crap back into its carton, place it aside and write a warning to my colleague rather to throw that thing into the garbage directly or at least to not switch it on, before taking it apart.
So far I'ld say the power supply is worth the money though it may be wise to ckeck the isolation clearances as I did.
No, I disagree fully.
A device which is inherently unsafe, which is a possibly lethal accident waiting to happen, is certainly not worth any money at all.
Just keep off of that crap ... and best return the garbage back to it´s sender.
I´m beginning to think that dumb ol´ Trump might be right with his taxation plans against china
Taxes and customs can´t be high enough to prevent such crap beeing sold to decent countries.
Not to think of what useful could have been built from those now wasted resources.

Calvin
KingKong ... I still can´t get it
