Hi everyone, I have a question. I have an industrial machine that runs on three phases without an N. I need to upgrade this machine by adding another machine and connecting it to the same control cabinet (signals need to be picked up). However, my machine runs on 220 V and needs an N. There…
In a power supply unit, I found an electromechanical part that I had never seen before and whose function is completely unclear to me. It is a Hoefer 500xt power supply (google for pictures) Inside is a part with two "wings" that hum when switched on and wave back and forth at a 50Hz rate….
Hello, Why are max. values for cables in amperes, but for resistors in watts? Don't cables also heat up due to their resistance? What's different about this compared to wire-wound resistors, where amperes are the deciding factor for cables? And a completely different question: With potentiometers, the maximum possible power (usually 2W) decreases the further…
Good bye, I wanted to build my own (adjustable) table and am stuck on an electrical/mechanical problem. I'd like to have the table raise and lower from a certain height at the push of a button. Is there a DC motor that I can use to set the end positions from 50cm to 100cm? PS:…
