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.
- 150W maximum output power
- High resolution： 1mV / 1mA
- Low ripple/noise
- Overvoltage/over current protection
- Multi-directional cooling system with smart fan
- 3.7 inch TFT LCD display
- Support RS232 & USB interface & SCPI Programming
- Dimensions: 117mm(L) × 194mm(H)× 295mm(D)
Part 1 gives an overview of various features of this power supply and shows measurement on Fluke 179 also.
Part 2 of the video is mainly about how to interface power supply using USB (Owon’s PC Software) or RS232 using SCPI Commands.
