Overview
Owon P4305 Programmable Power Supply is a single-channel power supply with a 0-30V voltage and 0-5A current range. The minimum voltage it can set is 10mV and it measures and displays the output voltage with a resolution of 3 decimal places. This is one of the biggest features of this power supply.
It helps a lot when you are bringing up your hardware and can see current changes with a resolution of 1mA or optimizing the design for power consumption.
The power supply is fairly accurate, you will be able to see in the Part 1 video where I have to show the measurements using Fluke 179 multimeter.

Features
Part 1 gives an overview of various features of this power supply and shows measurement on Fluke 179 also.
PC Interface
Part 2 of the video is mainly about how to interface power supply using USB (Owon’s PC Software) or RS232 using SCPI Commands.
SCPI Commands
Measurement Commands
- *IDN? (read manufacturers details like name, product number, serial number, etc.)
