Do you know from what serial number done this new board revision?
That is unknown at this stage.
Should be visible through the vent holes though.
For those asking for the serial number: DP8C1532014XX
@ wizzy = this is the serial number that from this and after they fixed the issue?
Today I received the DP-832 that I have ordered before one month.
I can't break the warranty tape to see inside and I can't to see well inside via the side holes because it was afternoon.
I worked with this without any load for an hour and push the sense of temprature from the side holes. I write maximum temperature 65°C with ambient 27-28°C.
For the next two hours with loads and no loads the temprature was 58-65°C.
The serial number is DP8C1533014XX.
Before I receive the psu, ask from Owon Dealer to my country to confirm me that this psu hasn't this issue. They contacted with Owon Service Depatrment in Germany and the answers that gave them was "We have fixed that problem and your mentioned product has not that problem".
Tomorrow with the light of day, I'll try to see better via the holes and perhaps take a good photo from this area of board.
