I actually like it this way.

I see "300" on the photo. Of course it's not granted the rating is real. Only load testing and temperature measurement can tell the truth.

I see the psu allows setting separate CV/CC and OVP/OCP. I don't get why OVP/OCP are needed.

Hi,

My video review about this supply (In French)

Hello everyone.

I'm thinking about to buy this power supply. Owners ... after a few months of use … are you satisfied with this?
I am new in electronics and I want learn about repairing notebooks, phones, etc ... one important question is: Can I find the short on the circuit with this supply?   … or if the short is there the output is turned off fast and automatically?

RedSky:
I note there is now a rebadged Owon P4603 model on the market:

Multicomp MP710087

I have bought one, looks almost identical inside and out to the Owon.  Edit: Except this one has USB connectivity as well as RS232, and newer firmware

At $315 it's fairly well priced for us Aussies, even with its noted issues.
