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) https://youtu.be/lUjqdLF8L-8 |

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? |

I note there is now a rebadged Owon P4603 model on the market: Multicomp MP710087 https://au.element14.com/multicomp-pro/mp710087/dc-power-supply-1ch-60v-3a-180w/dp/3227421 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. |
