I just received an MCH K305D supply
http://www.ebay.com/itm/141991049197I am still waiting for the second one (I asked them to be shipped separately to avoid having to get them through UPS or FEDEX and have to pay the ridiculous fees.
The main problem I found is that the supplied cable's earth lead is not connected!!!!!!! I have lots of cables around, so no problem. But still, another indication that people must be careful with those cheap devices.
I did not have much time to do deep testing.
Just a quick earth test for the chassis, a quick test that no live wire goes to the chassis, a quick look inside for something obviously wrong and some quick voltage verification with a DMM.
Apart from the faulty cable all seems to work ok.
Anyone has experience with them? Anything else I should test for?
My guess from the separate earth lead is that they are floating and can be connected in series right?
