DPS3003 DIY Portable Lab Power Supply

TslaNovember 23, 2019March 2, 20240

In this post, I will show my DIY portable power supply. The PSU uses the DPS3003 module. This module is rated for voltages from 0-32V and currents from 0-3A. You can get other models with higher or lower voltage/current ratings. The input voltage, however, must be in the range of 6-40V and your maximum output voltage is limited to your input voltage. In my case, the battery provides around 16V to the input so the output voltage can’t go higher than that.

DIY Power and Power Factor Meter

In this post, I will show my DIY power/power factor meter. The module itself was bought(of course) I just put it in an enclosure and added some cables to make measurements easier. This way I have a handy and cheap tool for measuring the power and power factor of any device that I connect to it. This thing is no professional instrument with great accuracy but it’s good enough for doing some basic measurements.
