Hi there. I have two panel mount 24v relays which are driven by 24v switch panel. Both relays when energised turn on a dc-dc converter 24 down to 12v then the loads connected to each relay are 12v loads. Problem I have is when both switches are turned on then one back off the relay stays...
A tiny DC to DC buck converter board is useful for many applications, especially if it could deliver currents up to 3A (2A continuously without heatsink). In this video, we will learn to build a small, efficient, and cheap buck converter circuit.
