Almost all electronics have some components (eg capacitors) that get "charged up" when the device is first powered up.
This means they draw a short 'burst' of current when they are first plugged in or powered on by a relay. This is the "inrush" current.
It matters because relays, switches, plugs/sockets and circuit breakers etc may all have a limit to the highest inrush current they can handle, as well as the maximum 'running' current.
In some cases you will not be able to add another fixture to a circuit because it will go over the maximum 'inrush' current, even though it will not reach the maximum 'running' current (max. power)
For me it's clear the inrush current, but it's a little confuse if I need to have all my electrical system prepared for 50A. What happened if I have 24 S4 units power it at the same time!
I'm looking for led equipment and I'm very interesting in this S4 -because all the equipment that already have it's S4- Could you give a little bit more orientation?
