Скачать или смотреть SZBK07 DC-DC converter with multiturn potentiometers

In this video I show you how to replace the built in potentiometers of the SZBK07 DC-DC converter for multiturn potentiometers. The multiturn potentiometers allow more precise current and voltage adjustment. There are two main things to keep in mind:
1.) Do not use different potentiometers. The original potentiometers are 100 kOhm, so use 100 kOhm replacement potentiometers.
2.) Be careful about the polarity of the replacement potentiometers! Those which I present have their wiper (output) pin at the end and not in the middle as most of the traditional potentiometers.
