This e-mail from AAC arrived in my inbox the other day, and I still can't make any sense out of it.
Extracting DC from AC without magnetics - well - that's easy - it's called a diode. But extracting DC from AC without rectifiers and smoothing capacitors?
The whole thing seems like a bunch of marketing nonsense to me, and they are expecting us to replace our MCBs with these things that can supposedly decide within a millisecond whether an overcurrent situation is a fault of just an inrush?
Give me a fuse any day.
