Variable Voltage Power Supply Modification

Описание к видео Variable Voltage Power Supply Modification

This Drok 24V/20A power supply is great to power my Cobra 29 radio that can handle 15+ volts DC. However, the 10K voltage adjusting potentiometer that came with it is far too sensitive. So I bought a ten turn 10K potentiometer to make the adjustment about ten times less sensitive. This way if I bump the knob the voltage won't jump so much. Prior to doing the modification if you just bumped it with your hand, the voltage could change by as much as +/- 4vDC. And I know how real life works, so I wanted to change this as soon as possible to avoid catastrophe. I'm just sharing the simple steps I took to make this happen and make the power supply more useable in my mind.
