Tronic:
Hi All
Just wondering if anyone has successfully used this power supply to grid charge a hybrid Toyota battery?
Thank you in advance

Hi All, i recently bought the HSPY-1000-001. Came with a nice chinese manual. Only this forum, had a tread on this power supply, and dpenkler posted some documents that helped me getting the device programmed. It took me way to many time, so i would like to share how i got it working.
You will find the info in the attached documents, the powerdc document is the dos batch file

Kind regards, hoping to help some future buyers!

Anybody else get tonnes of common mode noise on the output of these?

I picked up one of these a few months ago (the 1000V version) for a project I'm working on and until now hadn't even looked at the output noise as it was not at all critical for that. Last night though I tried to use it for something else and finally saw the output. I was blaming my circuit for a while until I started isolating things and realised that it was coming from the supply itself.

Basically as long as the mains plug is in, and even if the unit is off, there's a tonne of 50Hz present at the outputs. I've since idiot checked myself by plugging into every other power supply I have on hand and everything is nice and clean, but with the HSPY it's hum-town.

Yeah there are some Y-caps in dumb places, see an earlier post I made. If you get rid of them like I did then it doesn't hurt to put a film cap to earth from the output to fix some of the HF noise you're left with.

Are there any schematics floating around or did you just trace things out? I just popped the lid off mine thinking I might give it a tune up in a spare 5 minutes before work, but it's so densely packed around the output terminals I can't see much, and pulling it apart looks like a pain in the ass so I'm gonna go back to it later (hopefully without having to gut it and trace out too much)
