OWON P4305 Lab Power Supply Review (6): Final Tests, Menus, RS232 & Wrap-Up

[@BobMellor1954]

Hi, thanks for the final review; I use a cheap linear PSU from China, it provides 0 - 15V at 5 amps max; so far the unit has proved to be reliable.

[@robertssmorgasbord]

You're welcome! Most power supplies, even the cheapest ones form China, usually work out of the box. I guess I was really unlucky with that unit. Anyway, if it still runs after 10 years you can call it "quality" ;-)

Great Review. Very informative. Will love to see a similar review for Rigol DP711

[@robertssmorgasbord]

Thanks for the praise! Unfortunately I currently don't need a second lab power supply, and I don't want to shell out 350 bucks for a RIGOL DP711 just to review it. But maybe RIGOL sees this and sends me a demo unit ;-)

What's the Rigol rival for Owon P4305 you mentioned at the end of the video?

[@robertssmorgasbord]

@@mrv4757 That would be the Rigol DP711 (also 30V/5A/150W, but goes for about 350€).

Great finish to your review, seems an OK supply if your demands are not to high, I wonder if the RS232 issue can be fixed with some stout cable and a cap ?...cheers.

[@robertssmorgasbord]

Thanks! And yes, the RS232 issue should be easy to fix by botching a 1uF capacitor onto that serial interface board. Something I'll probably do as soon as the warranty period is over. But then I'll need a proper USB to RS232 converter, 'cause the Chinese one won't take the negative voltages :-)

Bye :D

[@robertssmorgasbord]

Yeah, somehow that became my trademark :-)
